TELEPERM M process control system

The TELEPERM M process control system provides all functions required for process automation. It is highly suitable for the complete automation of continuous and discontinuous (batch) processes.

The TELEPERM M systems are divided into function units optimized for different tasks associated with process automation:

•AS automation systems

•OS operator systems

•CS and PROFIBUS bus systems



AS automation systems

The various TELEPERM M automation systems have different designs, ranges of functions and performances. The AS 235, AS 235 H and AS 235 K automation systems described in this catalog are proven and reliable. They can be configured within wide limits and coupled to a wide range of subordinate systems. The AS 235 H additionally has a redundant central unit and thus satisfies particularly high availability demands. The AS 235 systems can communicate with one another and with higher-level systems via the TELEPERM M CS 275 plant bus.

A wide range of TELEPERM M input/output modules is available for connection of the process peripherals (sensors and final control element systems. Some modules have their own processing features or can be configured application-specific.

The AS 388/TM and AS 488/TM automation systems (see Catalog PLT 112) use the SIMATIC M7-300 and M7-400 automation computers as the hardware platform and are compatible with the AS 235 system. They are appropriate for the extension of existing TELEPERM M systems or for the design of new systems.

The AS 388/TM and AS 488/TM systems can be operated on the PROFIBUS-TM plant bus. PROFIBUS-TM is based on the standardized PROFIBUS. The A operated on the CS 275 plant bus.

ET 200M distributed I/O systems with a comprehensive range of I/O modules can be connected to the AS 388/TM and AS 488/TM systems via one or two PROFIBUS-DP interfaces.



OS operator systems

The bus-compatible OS 525 (Catalog PLT 122) and WinCC/TMOS (Catalog PLT 123) operator systems are used for process communication. They communicate with the subordinate TELEPERM M automation systems and with SIMATIC S5-155U via the CS 275 plant bus or PROFIBUS-TM.

The operator systems can have a configuration variable from a single-user system up to a multi-user system - where the OS basic unit communicates with several terminals via a terminal bus - and can thus cover the complete range from low-end to high-end applications.

The PROGRAF AS+ configuring software is used for the AS 235, AS 235 H, AS 235 K, AS 388/TM and AS 488/TM automation systems and offers a wide range of support for documentation and configuring by means of a graphic functional diagram editor and an integrated database, amongst others.

Any single-user system WinCC/TM-OS-Single with RC license (Runtime+Configuration) is suitable as the configuring system for WinCC/TM-OS, and an OS 525 single-user system/terminal with OS 525-BIPRO configuring software for OS 525.

Plant bus

The plant bus is the central communication component of every distributed process control system. Two different bus systems are available for the TELEPERM M process control system, and can also be combined together within a system:

•CS 275

• PROFIBUS-TM The CS 275 plant bus which has been proven in many automa-

tion plants is predestined for communication between the AS 235, AS 235 H, AS 235 K and AS 488/TM automation systems and the OS 525 and WinCC/TM-OS operator systems. The CS 275 plant bus functions according to the token passing principle and can also have a redundant configuration. Several buses

can be combined together using bus couplers such that bus networks are produced corresponding to the plant structure. The bus system is provided with distributed control. The bus interface of each subsystem may take over the master function according to specific criteria.

The AS 388/TM and AS 488/TM automation systems and the OS 525 and WinCC/TM-OS operator systems can be connected to the PROFIBUS-TM plant bus. The PROFIBUS-TM is characterized in that it complies with the modern PROFIBUS communication standards to EN 50170 but also uses the TELEPERM M communication mechanisms of the CS 275 (AKS, BKS, MK PL/PS telegrams) at the user level (link between bus interface and application).

The PROFIBUS-TM plant bus also operates according to the token passing principle. It can be designed as an electrical or optical network. The two network instructions can also be mixed together. PROFIBUS-TM is preferably used for new systems or partial systems.

The CS 275 and PROFIBUS-TM buses can be connected together by a CS-L2 bridge, thus permitting linking of existing systems and new systems.

Note: Information systems, computers from other manufacturers, personal computers and gateways can be connected to the C plant bus. Personal computers with the Win TM software package can also be connected to PROFIBUS-TM.

Functions of the AS 235 system

The AS 235, AS 235 H and AS 235 K automation systems provide all I & C functions such as measurement, supervision, calculation, closed-loop control and open-loop control, also particularly taking into account batch processes. The automation systems also handle the tasks for local operation and monitoring, e.g. display, signalling, alarm output, process operation and logging.

The AS 235 and AS 235 K only differ in their design. The AS 235 system is fitted in a cabinet, the AS 235 K system in a wall housing. The AS 235 H system with a redundant central unit is provided for applications with particularly high availability demands.

A large range of dedicated function blocks is available for ing I & C tasks in the AS 235, AS 235 H and AS 235 K automation systems. “Programming” of the automation systems is thus made extremely simple since the function blocks present in the system memory need only be activated by entering configuring instructions and parameters.

In addition, the AS 235, AS 235 H and AS 235 K permit the use of additional languages for special tasks - such as optimization, startup and shutdown of open-loop controls - which are difficult to solve using the existing function blocks or the batch functions. The TML process language (TELEPERM M Language) is available for analog and binary processing operations, as well as STEP M control language already known from the SIMATIC industrial automation system. TML/STEP M can be used to define new function blocks optimally tailored to the respective task. Despite an extremely high degree of freedom, the clear and transparent “Block technology” is not relinquished. Frequently occurring block combinations can be combined into socalled Typicals and can then be used just like a single block.

A wide range of input and output modules is available for the AS 235, AS 235 H and AS 235 K systems as the interface to the process.

Intelligent I/O modules, e.g. modules which can carry out closed-loop control functions on their own, make it possible to configure a subordinate individual single-loop control level. This increases the availability of the automation system even further.

the

Further to this, the proce lar for power applications or distributed small systems by sys- tem-compatible coupling of SIMATIC components.

The AS 235, AS 235 H and AS 235 K systems have either one or two autonomous operation channels for local operation and monitoring. This means that the process operation keyboard, process monitor and printer can be connected to each of the two operation channels and carry out operation and monitoring functions independent of one another.

In addition to the standardized displays which are achieved by addressing the automation function blocks without carrying out any further configuring, the user can also configure free dis- plays. A standardized display is e.g. the loop display for operation of a control loop, a free display is the schematic representation of plant components (flowcharts) in their respective process status.

The local operation devices may be omitted when using central operation and monitoring in a network configuration.

Configuring

Configuring includes the incorporation of the automation structure into the automation system by using configuring instructions, by specifying parameters, by programming with TML and STEP M if applicable, and the feedback documentation.

This is possible either without an additional programming device/personal computer directly on the automation system (direct configuring, input/output using lists) or by using a PROGRAF AS+ engineering tool on a programming device/PC. Both configuring methods can be used

• locally for one automation system or

• centrally from one AS 235 system or one PC with

Performance characteristics

The AS 235, AS 235 H and AS 235 K systems are programmable automation systems of the TELEPERM M process control system based on function blocks. They have a different design and availability, but the same range of functions. The AS 235 K sys- tem is fitted in a wall housing, the AS 235 and AS 235 H systems are fitted in cabinets. The AS 235 H automation system has a redundant central unit to satisfy particularly high demands placed on the availability.

The systems can either be used on their own with local operation and monitoring, or coupled in system networks with central operation and monitoring.

System configuration

The automation sys

•A basic unit (AS 235, AS 235 H) or a basic system (AS 235 K)

•ES 100 K extension systems (wall housing) or extension units (for fitting in cabinets) as extension for configuring with input/ output modules.

Standard input/output devices enable local communication with the automation system during the configuring and commission- ing phases as well as during later operation. The following can be connected:

• 54-cm (21-inch) process monitors

• Process operation keyboard and configuring keyboard, max. 2 of each for 2 independent operating consoles

• Max. 4 logging printers

• 1 mini floppy disk unit for booting the system memory and for loading/saving the user memory.

Basic system/basic unit

The basic unit (AS (AS 235 K) mainly contains

• the power supply modules,

• the central processor module,

• a memory module with user memory with 4,000 Kbyte capacity and battery backup and

• the interface modules for the input and output devices and the CS 275 bus system,

each of which is redundant in the AS 235 H system. The central processor is microprogrammed and has a maximum

processing width of 32 bits. Three basic cycles are present for processing (125 ms, 1 s and background level). An acyclic mode can also be defined.

The basic unit of the AS 235 and the basic system of the AS 235 K each has 6 slots for I/O modules. No I/O modules can be plugged into the ba

The following can be fitted into the systems as standard:

•AS 235 Max. 90 I/O modules

•AS 235 H Max. 91 I/O modules

•AS 235 K Max. 108 I/O modules

The number of usable I/O slots with the AS 235 and AS 235 H can be increased by additional use of ES 100 K extension sys- tems:

I/O modules

There are the following group

• S ignal modules

• Function modules

• Calculation modules

• Coupling modules.

Signal modules are required for input and output of the process signals, usually without further processing (exception: adapta-

tion of characteristic with temperature measurements). Function modules (closed-loop control modules) and calculation

modules have additional performance features which are independent of the central unit of the automation system and which can be used to increase the total processing performance or the availability by transferring backup functions should the central unit of the automation system fail.

The calculation modules enable the configuring of individual user functions.

Coupling modules enable the connection of I/O modules over larger distances. They additionally enable use of non-intelligent I/O modules of the SIMATIC S5 programmable controller the ET 100U distributed I/Os for the automation systems.

Memory, configuring

The memory with battery backup of the automation systems is divided into:

•a system memory and

•a user memory. The write-protected system memory contains the software which

always belongs to the automation system, in the form of basic programs and function blocks. Far more than 100 standardized blocks are available for data acquisition, closed-loop control, open-loop control, calculation, supervision, logging, display and operation/monitoring.

Instead of programming the system with individual commands and carrying out the required program tests, it is only necessary in the TELEPERM M process control system to configure the complete function blocks in order to obtain a “user program”. In the simplest case, configuring means calling the function blocks with the keyboard, several times if necessary, and then assign- ing the respective linking instructions and parameters. The resulting application-oriented configuring data are then stored in the user memory.

Configuring is possible before the automation system is started up as well as during operation. It is possible to temporarily switch partial functions of the user system out of operation for this purpose.

Convenient configuring using graphic inputs is possible using the PROGRAF AS+ engineering tool which can be executed in a personal computer connected locally to the AS 235/235 H/235 K automation

system or centrally to the CS 275 bus system.

STEP M

In addition to the function blocks for binary processing, the AS 235/235 H/235 K systems can use the STEP M control language, without leaving the block configuration, in order to formulate extensive and complex open-loop control tasks.

TML language

The TML process language can be used in addition to the firmware blocks for special tasks. It can be used to format special function blocks and to implement particularly complex functions, e.g. for the mixing of binary value arithmetic and measured value arithmetic.

Operation and monitoring

The AS 235, AS 235 H and AS 235 K systems have either one or two autonomous operation channels for local operation and monitoring. This means that process operation keyboards, printers and process monitors can be connected in duplicate and operated using operation/monitoring functions which are independent of one another. Some of the local operation devices can be omitted in the cas a network configuration.

Scope of performance

The user RAM of the automation systems has a memory capacity of 4,000 Kbytes. This means that even one single system can already implement larger automation tasks. Even the data quantities encountered with extensive batch processes can be handled. If it is taken into account that various tasks occur mixed together, the performance is approximately as follows:

• 30 to 80 control loops

• 50 to 120 additional analog-value monitoring functions

• 5 to 15 sequential controls

• 100 to 250 logic controls

• Any number of flow charts (up to 8 colors) and individually designed logs.

Redundant path

Various system characteristics must be considered with regard to the reliability and availability of a system. The requirements for reliability are met by fault-tolerant (high-availability) systems while those for safety are met by fail-safe systems.

According to VDI/VDE 3542 the following applies: A system is fault-tolerant if occurring faults have no effect on its function. Fail-safe is the ability of a technical system to remain in a safe mode or to switch immediately to another safe mode in the event of a fault.

The AS 235 H automation system is a high-availability system with redundant central units operating with system clocks where execution of the planned automation functions is not interrupted by system faults.

The system operates according to the fault-tolerant 1-out-of-2 principle. The AS 235 H system is equipped with 2 identical central processing units for this purpose, the master unit and the slave unit (Fig. 2/1). Each of the two CPUs contains a power supply module, central processor, memory module for system software and user program as well as 1 or 2 interface modules for the I/O bus depending on the number of I/O modules connected. The user programs stored in the 2 memory modules are identical.

Process signals are always applied to both CPUs. Only one of these, the master unit, can output commands to the process via the I/O modules. The other operates in hot s

tandby mode and is always able to take over smooth control of the process should the master unit fail.

The fully-synchronous mode of operation of the two partial AS 235 H systems means that any assignment of the master is possible: master/slave or slave/master. Both partial systems are updated with the same information simultaneously because all input data are applied to both, meaning that online backup data transmission between the two partial systems is superfluous.

Central faults are detected very rapidly using a hardware comparator. This compares the redundant bus signals for each read or write operation of the central processors operating with synchronous clocks. Software test programs are started in the event of a fault in order to established its location.

The synchronous signals of the redundant I/O bus are checked for equality for selective areas of up to 13 I/O modules each and converted to the single-channel I/O bus of the standard I/O modules. Up to 3 selected I/O module areas can be supplied by the redundant I/O bus (A), a further 4 selected I/O module areas can be supplied by extending with a redundant I/O bus 2 (B). A strict division into fault limiting regions thus ensures

that single faults

can only have an effect within one selective I/O module area. The AS 235 H system enables maintenance and repair without

interfering with process operations. The corresponding partial system, irrespective of whether it is the master or slave, is removed from the synchronous operation. The partner system then retains the master status, or is assigned it automatically, and thus handles the active process operations. The disabled, passive partial system now operates completely independently, but without the I/O modules since these are required by the mas- ter.

This simplex operation with 2 independent systems enable

s new user programs to be configured, loaded or tested and to operate on the process either on a trial basis or permanently. This flexibility prevents undesirable down times in the process when changing the automation structure.

The backup of a passive partial system (transition from simplex to duplex operation with a slave system ready for operation) is initiated by the operator and is executed without influencing the online processing of the master system. It is terminated by automatic synchronization. The second partial system is then the slave and is ready to accept the master status at any time.

When connected to the CS 275 bus system, the redundant AS 235 H system re

sponds like a single participant.

The user software of the AS 235 H automation system is compatible with that of the AS 235 and AS 235 K systems, i.e. user configurations which have been generated on these systems and which function directly can also be used in the AS 235 H system without limitations.

Important note:

The AS 235 automation system has been optimized for high reliability and availability by means of fault tolerance and a non-interacting design. However, it does not belong – just like any other single or redundant programmable system – to the class of special fail-safe systems approved by independent testing authorities

(e.g. TÜV).

It is therefore important when automating processes or pro- cess sections relevant to safety to ensure that suitable subordinate interlocking circuits or protective systems are provided for these areas in the AS 235 H system as in the AS 235 / AS 235 K systems which make a dangerous operating state impossible should faults occur in the automation system.

Standard function blocks

Dedicated function blocks are present in the automation sys- tems to solve the control tasks. These are the so-called standard function blocks. The AS 235, AS 235 H and AS 235 K systems have the same standard function blocks for data acquisition, closed-loop and open-loop control, calculation and monitoring.

The standard function blocks present in the system software are activated by engineering tools using configuring instructions. The blocks are combined into an automation structure which is processed cyclically, and sometimes acyclically, by the central processor of the automation system.

The configuration of the automation structure is us

ually generated graphically using the PROGRAF AS+ configuring tool (see also page 2/9).

General

The AS 235 automation system is available in three different versions:

• AS 235 cabinet version,

• AS 235 H high-availability cabinet version and

• AS 235 K compact version. The I/O modules in the AS 235 and AS 235 H automation sys-

tems are in 6-

high subracks of the ES 902 packaging system, the extension units, which are only suitable for cabinet installation. A further 6 slots for I/O modules are available in the AS 235 basic unit.

The extension units are first installed in the basic cabinet of the AS 235/AS 235 H systems according to the numbers required for the respective automation task. If the basic cabinet is full, the remaining extension units are accommodated in the extension cabinet.

An AS 235 system can be fitted in this manner with up to 90 I/O modules, an AS 235 H system with up to 91 I/O modules. The number of available I/O slots can be increased to max. 114 (AS 235) or max. 103 (AS 235 H) by using additional ES 100 K extension systems.

In contrast to the AS 235 K automation system, the AS 235 and AS 235 H systems installed in cabinets are primarily designed for central configurations (Fig. 3/1b).

The main selection criterion for the AS 235 H system is its high availability.

The AS 235 K compact version is the smallest operable AS 235

automation system. It is fitted in a 15-

1) high subrack of the ES 902 packaging system (DIN 41494) which in turn is installed in a sheet-steel housing with degree of protection IP 21. The housing is designed for wall mounting.

The basic system of the AS 235 K has 6 slots for I/O modules. Up to 8 independent ES 100 K extension systems can be connected, thus increasing the total number of I/O modules to 108.

The ES 100 K extension systems can be installed up to 500 m away from the AS 235 K automation system.

For these reasons, the AS 235 K system is primarily suitable for distributed configurations (Fig. 3/1a) in small and medium-size plants or as a stand-alone system.

AS 235 automation system

The AS 235 automation system is the cabinet version of the range. It can be ordered in the form of two ordering units: basic cabinet and extension cabinet:

The basic cabinet is the main component of the AS 235 automation system. It contains all components required for the AS 235 system to function. It can therefore also be used on its own, i.e. without an extension cabinet.

The extension cabinet increases the number of slots for I/O mod- ules. It can only be operated in conjunction with the basic cabinet with up to 3 extension units. When using an extension cabinet it is possible to increase the number of slots for I/O modules in the basic cabinet (48) up to a maximum of 90.



Basic cabinet

The basic cabinet consists of the following main components:

Basic unit

The basic unit of the AS 235 automation system consists of:

• Subrack – For wire-wrap system 6DS9 026-8AB – For Maxi-Termi-Point system 6DS9 026-8AA

• Power supply subrack with – Slots for power supply and logic modules and – 6 slots for I/O modules

• Power supply module – DC 24 V / DC 24 V C79451-A3260-A25 – DC 24 V / DC 5 V C79451-Z1359-U9

• Alarm logic module 6DS1 901-8BA

• Central processing unit with – Central processor module 6DS1 140-8AA – EDC memory module 4000 Kbyte 6DS1 844-8FA – Backup battery for memory module W79084-U1001-B2 – AS 235 system software, version G 6DS5 323-8AG – Interface module for I/O bus 1 6DS1 312-8BB

• Interface module for mini floppy disk unit 6DS1 326-8BB

• Interface module for operation channel 1 6DS1 330-8CA

• Bus terminator module C79458-L445-B20

• Cable duct, 2

• Cover with wiring duct 6DS9 927-8AA

• Cable set for power supply and alarms 6DS9 908-8CA

high 6DS9 906-8AB

The subrack for the basic unit of the AS 235 system corresponds

to the ES 902 system and is 10

high. It is the supporting system for the other components of the basic unit, the interface modules for the local bus, and the I/O modules. The process signal lines for the 6 I/O modules are connected to the rear, the plug connectors are equipped with wire-wrap or Multi-Termi-Point connections.

If the process signal cables leading to I/O slot 6 are to the connected in the cabinets also using the Maxi-Termi-Point system, conversion is necessary using SAE cabinet connection elements. These must be ordered separately.

The power supply module C79451-A3260-A25 is used to supply the basic unit with DC 24 V. The DC 24 V supply voltage is filtered and additionally fused on this module. Two process operation keyboards and a mini floppy disk unit can be powered with DC 24 V via 3 sockets on the front of the module.

The basic unit is equipped with 1 or 2 alarm logic modules depending on the configuration of the automation system. The alarm logic module ML1 is assigned to the basic cabinet. The alarm logic module ML2 is only required if the AS 235 system consists of a basic cabinet and an extension cabinet and has a basic unit with wire-wrap pins. In the case of the basic unit with Maxi-Termi-Point system, the tasks of the alarm logic module ML2 are handled by the interface module for I/O bus 2.

The alarm logic modules monitor the voltages each) and +5 V as well as the I & C signals for overtemperature, door contacts, fan contacts and spare contacts, and trigger the current lamps.

The central processor is especially tailored to the processing of closed-loop and open-loop control tasks and to the TML programming language. It divides the RAM and differentiates access operations to

• the 1-Mbyte system RAM with battery backup for all fixed system data and programs,

• the 4000-Kbyte RAM with battery backup for all user programs and data and for variable system data, and

• the transfer memories of the interface modules for I/O bus, operation channel, mini floppy disk unit and local bus.

The memory module with can correct a 1-bit error when reading, and eliminate it in the memory cell together with the system software.

The interface module for I/O bus establishes the connection between the 8-bit central unit bus and the I/O bus. One or two of these modules can be plugged into the basic unit of the AS 235 system:

• The interface module for I/O bus 1 (A) supplies the I/O modules plugged into slots 1 to 5 of the basic unit and the 3 extension units of the basic cabinet. It is always required, and belongs to the standard delivery of the basic unit.

• The interface module for I/O bus 2 (B) must the ordered as an option. It connects slot 6 for I/O modules in the basic unit and the 3 extension units of the extension cabinet to the central processing unit via I/O bus 2 (B). It is therefore only required if slot 6 in the basic unit is to be used, or if an extension cabinet is used in addition to the basic cabinet.

Standard I/O devices

The standard I/O devices such as process monitor, process operation keyboard, configuring keyboard, mini floppy disk unit and logging/message printers are described in Section 5.

The interface modules for operation channel generate the RGB signals for the process monitors. They also have three 20-mA current loop interfaces to which the process operation keyboard or the configuring keyboard and 2 printers (logging and message printers) can be connected.

The interface module for operation channel 1 belongs to the scope of delivery of the basic unit and is always required. A second interface module is only required if 2 operating consoles are to be used via which operation and monitoring or configuring are to be carried out independently.

The combinations which can be ordered for the standard I/O devices comprise:

• PBT 65 process operation keyboard

• Configuring keyboard 6DS3 303-8AA with connecting cable, 1 m 6DS8 102-8AC

• Mini floppy disk unit with connecting cables for 6DS3 900-8AE signal transmission and power supply, 3 m each

Extension units

Depending on the complexity of the automation function, the capacity of the basic unit for I/O modules can be increased up to max. 90 slots by the addition of up to 6 extension units.

Extension units EE1 to EE3 are connected to the central processing unit via I/O bus 1 (A) and the interface module for I/O bus 1 (A). These extension units are accommodated in the basic cabinet. Extension units EE4 to EE6 are components of the extension cabinet and thus connected to the central processing unit via I/O bus 2 (B) and the interface module for I/O bus 2 (B).

An extension unit of the AS 235 automation system consists of a

high subrack with slots for 14 I/O modules (each 2 standard

6slots wide). 2 subracks with different process connections are available for

• Maxi-Termi-Point connections, pins 0.8 mm x 2.4 mm (recommended for direct connection of process cables) or

• wire-wrap connections, pins 1 mm x 1 mm (recommended for process cable connection via SAE cabinet connection elements).

I/O modules

The I/O modules are the process interface of the AS 235 automation system. They comprise signal modules and function modules, including calculation modules. See Section 4 for the properties, functions and Ordering data of the I/O modules.

The basic unit of the AS 235 system has 6 slots for I/O modules. A further 42 I/O modules can be accommodated in the basic cabinet by inserting into 3 extension units with 14 slots each. A further 42 I/O modules can be inserted into an additional extension cabinet with up to 3 extension units, thus enabling a total of 90 I/O modules per AS 235 system.

One ES 100 K extension system can additionally be connected per I/O bus.

During planning it should be noted that the 16 A with which each extension unit is fused must not be exceeded.

The I/O modules can be supplied coded, inserted and with labelled slots. Arrangement, designation and connection diagrams (including address data) are required from the orderer.

• Coding, inserting and labelling 6DS5 705-8AA for 1 I/O module

Power supply components

The standard DC 24 V power supply unit of the AS 235 system comprises:

• Power distribution subrack for DC 24 V 6DS4 407-8CA with slots for 2 bus converters UI, 8 automatic circuit-breakers, 1 supply diode, terminal and alarm strip, overvoltage protection

• Connection distributor for 20-m local bus 6DS9 207-8AA

• Flashing pulse generator 6DS1 922-8AA

• 3 cabinet power supply terminals C79165-A3012-D73

The power distribution subrack has separate automatic circuitbreakers for the basic unit and up to 6 extension units in the basic cabinet and the extension cabinets. The major functions of the power distribution subrack are:

• Supply of DC 24 V to a cabinet or a cabinet group

• Fusing of L+ and PM for the extension units and 24-V heat exchanger

• Separate supply of 2 bus converters with DC 24 V

• Combination of alarms as well as triggering of cabinet lamps and the cabinet row lamp (AS 235 H)

• Combination of cabinet lamps for the basic unit

• Generation of a flashing pulse for I/O modules of the TELEPERM ME process control system

• Supply of an external minutes pulse

• Connection distributor for 20-m local bus (e.g. for central configuring with PROGRAF AS+).

The DC 24 V supply is not redundant as standard. However, the power distribution subrack is prepared for a redundant supply of DC 24 V. A redundant supply of DC 24 V into the cabinet is also possible by installing a second supply diode and an extension set consisting of capacitor, a cable set and 2 cabinet supply terminals. These must be ordered separately.

The flashing pulse generator has 3 functions:

• Generation of a flashing signal which is required by the I/O modules of the TELEPERM ME process control system for alarm display (see Section 4 for modules)

• Signal lamp test using the LT key on the front panel (wiring optional)

• Electrical isolation of external time synchronization signals. The AS 235 can be synchronized using a minutes pulse.

Bus components

The TELEPERM M systems can communicate with one another via the CS 275 plant bus up to distances of 20 m (local bus) or 4 km (remote bus).

The local bus is redundant as standard. The remote bus can be redundant as an option.

Up to 9 participants can be interconnected as a local bus island via the 20-m local bus (each bus converter Ul counts as 1 participant). The total length of the connecting cables must not exceed 20 m.

Interface modules for 20-m local bus (e.g. N-AS and N-V.24) of local bus participants can be connected together at the front using cables 6DS8 201-8.. . These cables are only provided with a plug at one end. They must be connected 1:1 at the free end to the plug of the adjacent local bus participant. If a cable is not yet connected there, a front plug 6DS9 200-8AA is required in addition. The cable 6DS8 205-8.. with 2 plugs can be used as an alternative to the combination of cable 6DS8 201-8.. and front plug.

It is possible to connect a personal computer via the connection distributor for 20-m local bus in the power distribution subrack. It must first be integrated into the local bus via a cable connector 6DS8 201-8.. or, in the case of a remote bus connection, via a cable 6DS8 204-8LC / 6DS9 201-8CA (see connection unit). Central configuring and feedback documentation of the AS 235 can be carried out in conjunction with the PROGRAF AS+ engineering tool (cf. Section 2).

The AS 235 is connected to a single remote bus via the interface connection unit.

The AS 235 can also be operated on a redundant remote bus. 2 bus converters UI and 2 remote bus connector boards AF are installed in this case. The interface connection unit for redundant remote bus is required for the connection to a redundant remote bus.

AS 235 H automation system

The AS 235 H automation system is the high-availability cabinet version of the AS 235 range. In contrast to the simple cabinet version, the AS 235 H is of redundant design and operates according to the 1-out-of-2 principle.

More information on the topic of redundancy can also be found in Section 2, page 2/3 “Redundancy with AS 235 H”

It is possible to implement interruption-free operation with a fullyredundant basic unit, the I/O bus (redundant as standard), the I/O bus comparator and switchover modules, and redundant I/O modules.

The AS 235 H must be ordered in the form of 2 separate ordering units: the basic cabinet and the extension cabinet:

The basic cabinet is the main component of the AS 235 H automation system. It contains all components required for the AS 235 H system to function and is fitted with up to 3 extension units. It can therefore also be used on its own without an extension cabinet.

The extension cabinet is used to increase the number of slots available for I/O modules. It can only be operated in conjunction with the basic cabinet and can be equipped with up to 4 extension units. Together with the extension cabinet it is possible to increase the number of slots for I/O modules in the basic cabinet (39) to a total of 91.

The subrack for the central modules of the AS 235 H corre-

sponds to the ES 902 packaging system and is 10

high. It is the supporting system for the two central processing units, the comparator/coupling module and the interface modules for mini floppy disk unit, operation channel and 20-m local bus. The

high power supply subrack 6DS4 432-8AA accommodates

3the power supply modules required for the basic unit as well as the backup module.

The power supply module C79451-Z1359-U9 is used to supply the basic unit with DC 5 V. Each AS 235 H partial system is supplied from its own power supply module. The backup module compensates brief voltage dips in the DC 24 V supply.

The central processor modules of the AS 235 H basically correspond to those of the AS 235 system. The required clocks are no longer generated on the module itself but are supplied by the

synchronization module.

The interface module for I/O bus establishes the connection between the 8-bit central bus and the I/O bus. One or two of these modules can be plugged into the basic unit of each partial system of the AS 235 H system:

• The interface module for I/O bus 1 (A) is essential for partial systems I and II and is included in the delivery of the basic unit. Each of the two CPUs operating with synchronous clocks is connected to the I/O bus comparator and switchover modules (EAVU) of the basic cabinet via its own interface module and own I/O bus 1 (A). Both the two interface modules and the two I/O buses 1 (A) are redundant to one another. This enables two-channel, clock-synchronous triggering of the EAVU modules.

• The interface modules for I/O bus 2 (B) must be ordered additionally (one module for each partial system). The interface modules are only required if an extension cabinet is used in addition to the basic cabinet.

Each of the two partial systems has a synchronization module. The two modules are redundant to one another and linked together without feedback. Together with the comparator/cou-

pling module they constitute the central components of the

AS 235 H system responsible for the control, coordination and monitoring of the two partial systems. The synchronization module is also required for operation of a non-redundant basic unit.

Depending on the configuration of the automation system, the power supply subrack is equipped with one or more alarm logic

modules:

• Alarm logic module ML1 (basic cabinet with 1 partial system)

• Alarm logic modules ML1 and ML2 (basic cabinet with 2 redundant partial systems)

• Alarm logic modules ML1, ML2 and ML3 (basic cabinet with 2 redundant partial systems and extension cabinet).

The alarm logic models monitor the central processing units and the optionally used signal inputs for temperature monitoring, door contact, fan contact and spare contact. In the event of a fault, the cabinet lamps on the basic and extension cabinets are triggered via these contacts.

Standard I/O devices

The standard I/O devices such as process monitor, process operation keyboard, configuring keyboard, mini floppy disk unit, logging printer and message printer are described in Section 5.

No operation channel interface modules are essential if the AS 235 H is always operated and configured centrally. However, the use of an interface module is recommended for diagnostics. The operation channel interface modules must be ordered together with the standard devices.

In contrast to the AS 235 system, the process monitors, keyboards and printers in the AS 235 H are not directly connected to the operation channel interface module. The process motors are connected to the operation channel interface modules of the two partial systems via video relays. A video relay is assigned to each operation channel. The video relays ensure that the connected process monitors always display the same screen contents. The process monitors are connected to the active partial system when transferring to asynchronous operation. The video relays are also connected to the synchronization modules for this purpose.

The signal cables of the keyboards and printers are connected to the operation channel interface modules of the two partial systems via distribution cables.

The keyboard and printer distributors as well as the video relays are components of the parts set for operation channel switchover which belongs to the delivery of an operation channel. An additional printer distributor is required if a second printer is to be connected to an operation channel, and must be ordered separately (option).

Possible connections and a summary of connecting cables: see page 3/29 ff.

The combinations which can be ordered for the standard I/O devices comprise:

• Interface module for operation channel 1 6DS1 330-8CA (with redundant basic unit: 2 off)

• PBT 65 process operation keyboard

• Configuring keyboard 6DS3 303-8AA with connecting cable, 1 m 6DS8 102-8AC

• Mini floppy disk unit with connecting cables for 6DS3 900-8AE signal transmission and power supply, 3 m each

• Parts set for operation channel switchover C79165-A3012-D70

• In addition for operation channel 2: – Interface module for operation channel 2 6DS1 330-8CA

Extension units

Depending on the complexity of the automation function, the capacity of the AS 235 H can be increased up to max. 91 slots for I/O modules by the addition of up to 7 extension units.

The extension units EE1 to EE3 are connected to the basic unit via 2 separate, redundant I/O buses 1 (A). Each of these buses is connected to the CPU of an AS 235 H partial system via a separate interface module for I/O bus 1 (A). These extension units are fitted in the basic cabinet.

Extension units EE4 to EE7 are fitted in the extension cabinet. These are also connected to the CPU of an AS 235 H partial system via 2 separate I/O buses 2 (B) which are redundant to one another, each of which has its own interface module for I/O bus 2 (B).

An extension unit of the AS 235 H automation system consists of a subrack with slots for 13 I/O modules, I/O bus comparator and switchover module, and a DC 5 V power supply module.

When ordering the extension units it is possible to select whether the extension unit EE1 is to be delivered on its own, together with EE2, or together with EE2 and EE3.

The following components are supplied:

• 1, 2 or 3 subracks with slots for 13 I/O modules – For wire-wrap system 6DS9 002-8BB – For Maxi-Termi-Point system 6DS9 002-8BA

high 6DS9 906-8BB

The extension units are supplied directly with DC 24 V from the power supply subrack. Each extension unit is fused separately with 16 A on the power supply subrack. The DC 5 V supply is taken from the power supply module DC 5 V.

In addition to the I/O modules, the interface module for 20-mA local bus N-V.24 can be inserted into the I/O slots of the AS 235 H system. One interface module N-V.24 can be inserted per interface module.

Accessories for the extension units: see Ordering data “Further options for AS 235 H basic cabinet”.

I/O modules

The I/O modules are the process interface of the AS 235 H automation system. They comprise signal modules and function modules, including calculation modules. See Section 4 for the properties, functions and Ordering data of the I/O modules.

Up to 13 I/O modules can be inserted into each of the extension units (max. 3) of the basic unit. Please observe the max. thermal loading (see standard cabinets and accessories, page 3/23). A further 52 I/O modules can be inserted into an additional extension cabinet with up to 4 extension units, thus enabling a total of 91 I/O modules per AS 235 H system.

One ES 100 K extension system can additionally be connected per I/O bus 1.

During planning it should be noted that the 16 A with which each extension unit is fused must not be exceeded.

The I/O modules can be supplied coded, inserted and with labelled slots. Arrangement, designation and connection diagrams (including address data) are required from the orderer.

Fig. 3/6 Example of redundancy with

I/O modules (1-out-of-2 structure)

Redundant process I/Os

Some of the I/O modules are suitable for producing a redundant process I/O area and for thus implementing an interruption-free automation system.

When using corresponding software structures generated by the user, it is possible to detect and signal the failure of an I/O module, to disable the faulty module for system interventions, and to continue data transfer via the redundant I/O module. Thus faulty modules can be replaced without operation of the individual loop.

Since the system redundancy ends at the I/O bus comparator and switchover module (EAVU), the I/O modules which are redundant to one another must be arranged in different extension units.

Power supply components

The DC 24 V power supply unit of the AS 235 H system comprises:

• Power supply subrack DC 24 V 6DS4 428-8AA

with slots for 2 bus converters UI, 24 automatic circuit-breakers, 2 supply diodes, 6 sockets for DC 24 V, terminal and alarm strip, overvoltage protection

• Connection distributor for 20-m local bus 6DS9 207-8AA

• Flashing pulse generator 6DS1 922-8AA

• Cabinet power supply terminals C79165-A3012-D73

for single supply

• Cabinet power supply terminals, extension set C79165-A3012-D74

for redundant power supply

The power supply subrack has separate fuses for the two partial subsystems of the AS 235 H. The major functions of the power supply subrack are:

• Redundant supply of DC 24 V in the basic cabinet or in the

basic and extension cabinets

• Fusing of DC 24 V for keyboards, mini floppy disk unit and heat

exchanger

• Separate supply of 2 bus converters with DC 24 V

• Combination of cabinet alarms for the basic unit

• Supply of an external minutes pulse

• Connection distributor for 20-m local bus (e.g. for central con-

figuring with PROGRAF AS+)

• Monitoring of central processing units and signal inputs of

basic and extension cabinets by the alarm logic modules

• Generation of a flashing pulse for I/O modules of the

TELEPERM ME process control system and the EAVU modules

The flashing pulse generator has the following functions:

• Generation of a flashing signal which is required by the I/O modules of the TELEPERM ME process control system for alarm display (see Section 4 for modules). The flashing pulse generator has two channels. The flashing pulses of the two channels can be synchronized. It provides a lamp test for the fault display of those I/O modules which are supplied with the flashing signal (optional wiring).

• Electrical isolation of external time synchronization signals. The AS 235 H can be synchronized using a minutes pulse.

Bus components

The TELEPERM M systems can communicate with one another via the CS 275 plant bus up to distances of 20 m (local bus) or 4 km (remote bus). The local bus is redundant as standard. The remote bus can be redundant as an option.

The central processing units of the two partial systems of the AS 235 H are each connected to the CS 275 bus system via an interface module N-AS. The interface modules handle all duties connected with transmission, including occasional control of data transfer. Only the interface module of the partial system with the master function is active. Thus the AS 235 H system acts on the bus as an individual participant despite the 2 connections for modules N-AS on the bus.

Interface modules for 20-m local bus of local bus participants can be connected together at the front using cables 6DS8 201-

8.. . These cables are only provided with a plug at one end. They

must be connected 1:1 at the free end to the plug of the adjacent local bus participant. If a cable is not yet connected there, a front plug 6DS9 200-8AA is required in addition. The cable 6DS8 205-

8.. with 2 plugs can be used as an alternative to the combination

of cable 6DS8 201-8.. and front plug. It is possible to connect a personal computer via the connection

distributor for 20-m local bus in the power distribution subrack. If the connection distributor is not integrated into the local bus via a connecting cable 6DS9 201-8FC, it must first be connected to the interface module N-AS via a connecting cable 6DS9 201-8LC. Central configuring and feedback documentation of the AS 235 H can be carried out in conjunction with the PROGRAF AS+ engineering tool (cf. Section 2).

The AS 235 H is connected to a single remote bus via the interface connection unit. The AS 235 H can also be operated on a

redundant remote bus. 2 bus converters UI and 2 remote bus

connector boards AF are installed in this case. The interface connection unit for redundant remote bus is required for the connection to a redundant remote bus.

AS 235 K automation system

The AS 235 K automation system is the compact version of the AS 235 system. Both systems use the same central unit modules, interface modules and I/O modules. They also have the same range of functions.

The AS 235 K system is fully operable on its own without any extensions. Since the number of I/O modules which can be plugged into the AS 235 K system is limited to 6, however, the AS 235 K is usually used together with ES 100 K extension systems (see page 3/21).



Basic system

The AS 235 K automation system is available for AC 230 V and DC 24 V supply voltages. The basic system of the AS 235 K automation system comprises:

• ES 902 subrack – For AC 230 V C79451-A3260-A16 – For DC 24 V C79451-A3260-A17 each with power supply subrack with slots for power supply and alarm logic modules, 6 slots for I/O modules process connection panel for I/O modules 1 to 6, mounting plate with slots for 2 connector boards AF “Remote bus” and slots for 2 bus converters UI, power supply unit, cable clamping rail with 10 clamps

• Power supply module SV1 For AS 235 K with AC 230 V: – AC 230 V / DC 24 V C79451-A3260-A20 For AS 235 K with DC 24 V: – DC 24 V / DC 24 V C79451-A3260-A25

• Power supply module SV2, DC 24 V / DC 5 V C79451-Z1359-U9

• Alarm logic module 6DS1 901-8BA

• Bus terminator module C79458-L445-B20

• Flashing pulse generator 6DS1 922-8AA

• Interface module for mini floppy disk unit 6DS1 326-8BB

• Interface module for operation channel 1 6DS1 330-8CA

The subrack of the AS 235 K system corresponds to the ES 902 system and is 15 components of the basic system, the bus components, and the I/O modules.

The front of the subrack contains a process connection panel for the process signal cables with Maxi-Termi-Point connections (pins 2.4 mm x 0.8 mm). The rear of the process connection panel is wired to the base plugs X2, i.e. the process interfaces of the 6 I/O modules in the basic system.

Two power supply modules are used for the basic system:

• Power supply module SV1 One of the following modules is used depending on the selected supply voltage for the AS 235 K: – C79451-A3260-A20 (AC 230 V / DC 24 V) or – C79451-A3260-A25 (DC 24 V / DC 24 V). Both designs are equipped with 3 sockets via which 2 process operation keyboards and a mini floppy disk unit can be powered with DC 24 V.

• Power supply module SV2 The power supply module SV2 (C79451-Z1359-U9) converts DC 24 V into DC 5 V for the central processing unit and the I/O bus interface modules.

The alarm logic module monitors the 24-V voltages L+ and PM, the +5-V voltage and the optionally used signal inputs for temperature monitoring, door contact and spare contact. Error messages via these signal inputs as well as further system messages trigger a flashing LED and a relay of the module at the same time. This common alarm can be switched via this relay to an external signalling lamp for another signalling device.

The flashing pulse generator has the following functions:

• Generation of a flashing signal which is required by the I/O modules of the TELEPERM ME process control system for alarm display. The flashing signal is fused in the flashing pulse generator

• Lamp test for the fault display of the I/O modules which are supplied with the flashing signal

• Electrical isolation of external time synchronization signals. The AS 235 K can be synchronized using a minutes pulse.

1) If I/O slot 6 is used, the interface module for I/O bus 2 (B) is required in addition. See AS 235 K functions for Ordering data.

Error Detection and Correction

EDC can correct a 1-bit error when reading, and eliminate it in the memory cell together with the system software.

The interface module for I/O bus establishes the connection between the 8-bit central unit bus and the I/O bus. One or two of these modules can be plugged into the basic system of the AS 235 K:

• The interface module for I/O bus 1 (A) supplies the I/O modules

plugged into slots 1 to 5 of the basic system and/or the interface modules for the ES 100 K extension system. It is always required.

• The interface module for I/O bus 2 (B) is only required if slot 6

in the basic system is to be used. It must be ordered as an option.

Standard I/O devices

The standard I/O devices such as process monitor, process operation keyboard, configuring keyboard, mini floppy disk unit and logging/message printers are described in Section 5.

The interface module for operation channel generates the RGB signals for the process monitors, including the CVS signal. It also has three 20-mA current loop interfaces to which the process operation keyboard PBT or the configuring keyboard and 2 printers (logging and message printers) can be directly connected.

See page 3/29 for possible connections of standard I/O devices and a summary of connecting cables.

The interface module for operation channel 1 belongs to the scope of delivery of the basic system and is always required. A second interface module is only required if 2 operating con-

• In addition for operation channel 2: – Interface module for operation channel 2

I/O modules

The I/O modules are the process interface of the AS 235 K. They comprise signal modules and function modules, including calculation modules. See Section 4 for the properties, functions and Ordering data of the I/O modules.

The AS 235 K has slots for 6 I/O modules. Slots 1 to 5 are connected to the central processing unit via I/O bus 1 (A). Slot 6 is connected to I/O bus 2 (B). As a result, the interface module for I/O bus 2 must be inserted if slot 6 is to be used.

The number of slots for I/O modules can be increased up to a maximum of 108 by connecting up to eight ES 100 K extension systems.

The I/O modules can be supplied coded, inserted and with labelled slots. Arrangement, designation and connection diagrams (including address data) are required from the orderer.

• Coding, inserting and labelling 6DS5 705-8AA for 1 I/O module

Interface module for ES 100 K

The interface module for the ES 100 K links the I/O bus of the AS 235 K basic system to the I/O bus of the ES 100 K via a cable. Interface modules are required in both the AS 235 K basic system and the ES 100 K extension system.

The interface module for the ES 100 K can be inserted into any slot for I/O modules in both the AS 235 K and the ES 100 K. A maximum of four interface modules for a total of four ES 100 K extension systems can be plugged into slots 1 to 5 in the AS 235 K.

The I/O bus 2 (B) only supplies slot 6. Therefore a further four ES 100 K extension systems can be connected serially to the interface module inserted there. The use of slot 6 requires that the interface module for I/O bus 2 (optional accessory) is inserted.

Bus components

1) This cable is only suitable for connection to the process operation key-

board or the signal distribution unit. A cable 6XV2 167-8B.. (order separately) is required for the direct connection to the basic unit of the AS 235 K system (operation channel).

2) Interface module for operation channel 1 is included in the basic system.

ES 100 K extension system

Up to eight ES 100 K extension systems can be connected in order to supplement the 6 I/O module slots in the AS 235 K system (max. 4 systems per I/O bus). Extension of the AS 235 system by the ES 100 K extension system is also possible.

Each ES 100 K system has space for 13 I/O modules. The number of I/O modules per AS 235 K automation system can therefore be extended to 108 (104 slots in the ES 100 K + 4 slots in the AS 235 K).

The extension systems can be connected with a cascade or radial configuration. The total cable length must not exceed 500 m.

An interface module 6DS1322-8AA is required for the coupling in both the basic system and the extension system. The interface module can be inserted into any slot for I/O modules in the AS 235 K and ES 100 K systems. Slot 1 should be preferably used, however.

The ES 100 K extension system is available for AC 230 V and DC 24 V. It consists of:

• ES 902 subrack, 15 U high – For AC 230 V C79451-A3260-A3 – For DC 24 V C79451-A3260-A4 each with power supply subrack, 13 slots for I/O modules, process connection panel for I/O modules, power supply system, cable clamping rail with 10 clamps

• Power supply module SV1 For ES 100 K with AC 230 V – AC 230 V / DC 24 V C79451-A3260-A20 For ES 100 K with DC 24 V – DC 24 V C79451-A3260-A25

• Interface module for ES 100 K 6DS1 322-8AA

The subrack corresponds to the ES 902 packaging system and

high. It contains slots for the power supply module, an

is 15 alarm logic module, and the interface module for ES 100 K and 13 I/O modules.

The subrack also contains a process connection panel with 576 pins 2.4 mm x 0.8 mm in the Maxi-Termi-Point system.

A power supply module is required for the extension system depending on the selected supply voltage of the ES 100 K:

• C79451-A3260-A20 (AC 230 V) or

• C79451-A3260-A25 (DC 24 V).

The same power supply modules are also used in the AS 235 K system.

The alarm logic module 6DS1 901-8AA can the ordered as an optional accessory. It monitors the 24-V voltages L+ and PM, the optionally used signal inputs for temperature monitoring, door contact, fan contact and spare contact, e.g. if the ES 100 K extension system is installed in a TELEPERM M standard cabinet and if cabinet messages are to be detected or cabinet alarm lamps are to be triggered.

An alarm detected in the ES 100 K system is not transmitted to the central processing unit of an AS 235 K automation system, however. Therefore it does not lead to the output of an alarm text on the process monitor.

Standard cabinets and accessories

The AS 235 and AS 235 H automation systems can be delivered in 400 mm or 600 deep standard cabinets with or without a heat exchanger. The following standard ordering configurations are available:

• Standard cabinet without heat exchanger, degree of protection IP 20, cabinet depth 400 mm

• Standard cabinet without heat exchanger, degree of protection IP 20, cabinet depth 600 mm

• Standard cabinet with heat exchanger, degree of protection IP 54, cabinet depth 600 mm

Options, to be ordered in addition:

• Upgrading set for standard cabinets, degree of protection IP 10 to degree of protection IP 20

• Fan subassembly

In the cabinets with degree of protection IP 20, heat dissipation is by means of through-ventilation. The outside air circulates through the cabinet and dissipates the produced heat. The disadvantage of this type of heat dissipation is that dirt may be deposited if dust is present in the ambient air. This disadvantage does not occur in cabinets with heat exchangers. The max. permissible thermal load is 700 W at an ambient temperature of 40 °C.

In the cabinets with heat exchanger (degree of protection IP 54), the air within the cabinet and outside remain separated. These cabinets must be used if the ambient conditions deviate from the permissible values as a result of rough operating conditions. Examples include the chemical industry, iron and steel industry, mining, and plants exposed to salty atmospheres. The max. thermal load is 1000 W at an ambient temperature of 40 °C.

The standard cabinet can be used either without forced ventilation or provided with one or two fan subassemblies depending on the permissible thermal load of the cabinet, the desired design and, especially, the I/O modules used.

The fan subassembly 6DS9 943-8AA is used for forced ventilation. This subassembly contains three fans whose speeds are monitored, as well as an electronic fuse.

In cabinets with heat exchangers, the fan monitoring functions of the fan subassemblies and of the heat exchanger are connected in series. The failure signal LK is connected to the basic unit.

Each standard cabinet has 2 thermostats to measure overtemperatures. See the following pages for configuring guidelines concerning the permissible thermal load.

The basic cabinets are always delivered without side panels and partitions since they can be installed individually, as double cabinets, or in a cabinet row depending on the location and the size of the system. Extension cabinets are supplied with one partition. The side panels and partitions must be additionally ordered as required.

Basic and extension cabinets can also be supplied as a double cabinet screwed together with a low-impedance connection.

A cabinet row lamp can be fitted into the top bezel panel of the first cabinet when installing cabinets in rows.

The rooms in which the cabinets are installed should be sufficiently large (ceiling height approx. 3 m). They should also be dry and dust-free. Air-conditioning must be provided if necessary.

Permissible thermal loading, configuring guidelines

Standard cabinets without forced ventilation

Basic and extension units fitted in standard cabinets can be operated without fans if

• the cabinet thermal load P cabinet unit temperature is not exceeded and

• a heat loss greater than 150 W does not occur in any extension system.

If many I/O modules are used with a high heat loss, these should not all be fitted next to one another but distributed amongst the various subracks in order to prevent heat accumulation. P is usually not achieved in the extension cabinet even with the full configuration of 42 I/O modules. An exact determination of the total heat loss is only required with a non-typical module configuration (many I/O modules of the same type, modules with more than 8 W heat loss).

Standard cabinets with degree of protection IP 20, with forced ventilation

Extension unit with > 150 W/subrack Basic and extension cabinets whose thermal load (without fan

subassembly) is not exceeded must be provided with forced ventilation if an extension unit is configured with I/O modules such that the heat loss of this subrack exceeds 150 W. At least one fan subassembly must then be provided between the basic unit GE and the 1st extension unit EE1 (in the basic cabinet) or between the 4th and 5th extension units (in the extension cabinet).

Cabinet thermal load > 350 to 450 W, < 700 W If the thermal load is between 350/450 W (depending on cabinet

ambient temperature) and 700 W, and if 150 W is not exceeded in any extension unit of the cabinet, at least one fan subassembly must be provided between the basic unit GE and the 1st extension unit EE1 (in the basic cabinet) or between the 4th and 5th extension units (in the extension cabinet).

A 2nd fan subassembly must be provided if an extension unit is additionally configured with I/O modules such that its heat loss exceeds 150 W. The 2nd fan subassembly must be fitted above the 3rd extension unit EE3 (in the basic cabinet) or above the 6th extension unit EE6 (AS 235, extension cabinet) or above the 7th extension unit EE7 (AS 235 H, extension cabinet).

permissible depending on the

s max

Standard cabinet with heat exchanger

The standard cabinet with heat exchanger can be operated without an additional fan subassembly if the total thermal load of 350/450 W (depending on cabinet ambient temperature) is not exceeded in the cabinet and if 150 W is not exceeded in any extension unit.

The standard cabinet with heat exchanger is operated with a fan subassembly if the total thermal load is < 700 W and if 150 W is not exceeded in any extension unit. The fan subassembly must be fitted between the basic unit and the 1st extension unit EE1 (in the basic cabinet) or between the 4th and 5th extension units EE4 and EE5 (in the extension cabinet).

If the thermal load in one of the three extension units exceeds 150 W or if the total thermal load exceeds 700 W, a 2nd fan subassembly must be fitted between the 2nd and 3rd extension units EE2 and EE3 (in the basic cabinet) or between the 5th and 6th extension units EE5 and EE6 (AS 235, extension cabinet) or between the 6th and 7th extension units (AS 235, extension cabinet). A maximum thermal load of 1000 W is then permissible.

Process signal cables, information on cable routing

The process signal cables should be screened installation cables for industrial electronics with color-coded conductors twisted in pairs and combined into bundles.

Highly suitable are SIMATIC cables with a conductor cross-section of 0,5 mm² (conductor diameter 0.8 mm). In these cables, 8 pairs of twisted conductors, each identified by different colors, are combined into a bundle. The conductors of each bundle have a special ring identification in order to differentiate the bundles.

Process cables (< 60 V) must always be routed separately from power cables and high-voltage cables (> 60 V) (minimum spacing 20 cm). Depending on the plant it may be necessary to use a spacing of 1 m where large sources of interference are present.

If this spacing is not possible, the cables must be routed in metal protective tubes or in closed metal ducts with a continuous electrical connection. These must be earthed every 20 m.

Suitable overvoltage arresters for lightning protection must be provided when the cables enter and leave buildings.

Analog and binary signals must be routed in separate cables. Signal distribution cabinets and marshalling racks must be fitted

between the process I/O peripherals and the TELEPERM M standard cabinet in the case of larger plants. These are suitable for cross-connecting analog and binary signals and to enable grouped connections with appropriate colors in the TELEPERM M standard cabinet as a result of corresponding marshalling connections.

Connections for process signal cables

The process signal cables must be inserted into the cabinet (AS 235 and AS 235 H) or housing (AS 235 K) of the automation system from below. Their screens must be connected to the cable clamping rails.

The process signal cables can be connected either directly, i.e. to the base plugs X2 of the extension units (AS 235 or AS 235 H) or to the process connection panel (AS 235 K), or also via cable connection elements SAE (only AS 235 and AS 235 H).

Direct connection of process cables

In the case of a direct connection, the process signal cables are directly connected to the base plugs X2 of the I/O slots (AS 235 or AS 235 H) or to the process connection panel (AS 235 K) using the Maxi-Termi-Point system.

Base plugs X2 with wire-wrap connections are not suitable for direct connection of process signal cables.

The slots 1 to 5 for I/O modules of the AS 235 basic unit can be wired using the wire-wrap system or the Maxi-Termi-Point system. Slot 6 can only be wired using the wire-wrap system. The process signal cables leading to these slots must therefore not be wired directly. They must be converted via cabinet connection elements SAE (Maxi-Termi-Point/wire-wrap).

Connection of process signal cables via cabinet connection elements SAE

Using cabinet connection elements (SAE) it is possible

• to marshall within the standard cabinet between the cabinet connection elements and the subracks,

• to convert the standard connection system (Maxi-Termi-Point or wire-wrap) into a different system or

• to connect process signal cables to the front.

If requested by the customer, the internal system wiring between the cabinet connection elements and the base plugs X2 of the subracks can already be carried out in the factory. If this is required, an SAE locating and labelling diagram as well as an SAE wiring list must be enclosed with the order.

2 basic elements are available:

• Cabinet connection element SAE 32/3 (6DS9 907-8BA) Process side: Maxi-Termi-Point pins

2.4 mm x 0.8 mm

Internal: Wire-wrap pins 1 mm x 1 mm.

• Cabinet connection element SAE 32/1 (6DS9 907-8AA) Process side: Maxi-Termi-Point pins

2.4 mm x 0.8 mm

Internal: Maxi-Termi-Point pins

2.4 mm x 0.8 mm

The cabinet connection elements are mounted by latching into the SAE bars on the left side of the cabinet.

Any length of cabinet connection element blocks can be produced. The bottom basic element in each case is secured using 2 Fillister head screws.

A pair of labelling cards is required for each group of 4 basic elements to label the front and rear pins. 2 types of labelling are possible:

• For numbering of the 32 pins of a basic element from 1 to 32 or 32 to 1 (labelling cards 6XP1 846 and 6XP1 847)

• For identifying groups of 8 pins of a basic element by A to H, e.g. for cables with color codes for 8 conductors (labelling cards 6DS9 906-8DA).

The basic elements are numbered with the corresponding labelling strips according to the selected labelling cards:

• For labelling cards 1-32/32-1 for continuous or block-by-block numbering of the basic elements (labelling strips 6XP1 856)

• For labelling cards A-H/H-A for continuous or block-by-block numbering of the groups of 8 (labelling strips C79165-A3012-C99)

Additional elements are available for the two basic SAE elements and enable either screw terminal connections or plug connections at the process end. The additional elements are plugged onto the basic elements.

Summary

This section lists the available input and output modules of the TELEPERM M range. A detailed description of all modules (including those which are no longer available) with photos, functional diagrams and complete technical data can be found in Internet at:

http://www.ad.siemens.de/teleperm

in the section "Process I/Os - TELEPERM M".



Summary

The I/O modules constitute the interface of the automation system to the process. I/O modules of the TELEPERM M process control system are available for all common process signals, transmitters, final control elements and automation tasks associated with process engineering.

The I/O modules are divided into:

• function modules with autonomous functions independent of the central unit,

• signal modules (input/output modules without central-unitindependent interventions in the process) and

• counter modules.

Design

The I/O modules are designed as double-height plug-in modules with a front panel width of 30.48 mm. The front panel contains the module fuse, LEDs for diagnosis and error messages and – depending on the type of module – controls, test sockets or a plug for connection of a configuring device (configurable modules).

The I/O modules have 2 base plugs, the I/O bus interface and the process interface.

The modules are divided into 4 areas which are separated from one another by constructive measures and circuit features. Area 1 contains the hardware for non-reactive interfacing to the I/O bus of the automation system. This part is supplied via the I/O bus (= 5 V bus). Area 2 contains the interference suppression and protective circuits for the process signals. These prevent interfering signals from being transferred to the automation system via the process cables as well as the destruction of modules by overvoltages. Area 3 contains the power supply circuit of the module, area 4 the function-dependent processing circuit.

In the AS 235 system, a specific slot address is unequivocally assigned to each I/O slot. There are two types of I/O modules as far as addressing is concerned:

• I/O modules with jumper/slot addressing

• I/O modules only with jumper addressing

I/O modules with jumper/slot addressing should preferably be operated with slot addressing. The I/O module is then automatically assigned the slot address when inserting.

The slot address should be set on the I/O modules only with jumper addressing using the corresponding jumpers prior to inserting the module.

I/Omodules

Measures to prevent interference, short-circuit and overload

Great attention has been paid to an interference-proof and overvoltage-resistant design of the process interface.

The socket boards are divided into screening areas which are separated from each other by grounded surfaces. These screening areas attenuate and decouple the noise signals from the process such that the processing circuits of the I/O modules and the central unit are not influenced. All process inputs/outputs are provided with overvoltage protection circuits. Their overvoltage resistance of 1.5 kV at 1.2 requirements of the IEC standard 255-4, Class II and they function correctly up to a noise voltage of 1 kV and 1 MHz.

The CE certifications apply if the TELEPERM M installation guidelines are observed.

All analog and binary outputs are short-circuit-proof and overload-proof.

Power supply

The I/O modules only require DC 24 V as the supply voltage. All auxiliary voltages required by the module are generated by its own switched-mode power supply unit. Thus each I/O module can function on its own as long as the redundant DC 24 V system voltage is present.

As a result of the stand-alone supply and fusing of each I/O module, the modules are largely non-reactive with respect to the power supply. All internally generated voltages are monitored. Voltage failures lead to an alarm in the system. Failure of the module fuse is signalled by the separate alarm voltage the supply bus.

Module response upon failure of the automation system

Failure of the automation system (hardware fault, user configuration in stop status, central processing unit in stop status) is detected by the I/O modules.

The function modules have backup modes which enable operation independent of the central unit. The output modules (signal modules) react to a reset either by retaining the last output value or by switching to the safety setting. The desired reaction is configured on the module.

Monitoring, alarms

The functions of the modules connected to the I/O bus of the automation system as well as their interaction with the automation system are monitored by several mechanisms. Each I/O module monitors its own internal functions and signals e.g. power failure, blown fuse, hardware fault in module electronics to the automation system via the associated driver block.

The module for the I/O bus interface of the automation system detects missing or incorrectly addressed I/O modules as well as multiple addressing on the I/O bus. Faults in the firmware of the module are also detected and signalled by special acknowledgment procedures between the function modules and their drivers. The maintenance staff are specifically guided towards the location of a fault by means of alarms on the monitor and printer, lighting-up of cabinet lamps and LEDs on the front panels of the modules.

• High-availability, autonomous power supply for each I/O module; integrated power supply for transmitters

• Modules can be replaced during operation

• Comprehensive self-test routines on the modules

• Mutual test in dialog with the associated driver

• Fault diagnosis using I & C alarms, channel-specific up to the transmitter or final control element

• Tailored driver block for each type of module

• High electromagnetic compatibility; field inputs and outputs destruction-proof to IEC 255-4, Class II

• Selectable backup response of modules

• Configurable modules for processing independent of central unit

Configurable I/O modules

Function modules generally have a configuration which is defined by their firmware and which can be modified to a certain extent by plug-in jumpers (e.g. inversion of manipulated variable, internal/external definition of setpoint etc.).

The standard system software of the AS 235 automation system also contains driver blocks for configurable function modules from the device spectrum of the TELEPERM ME process control system for power plants. In this case, the firmware of these modules contains an interpreter which processes a user configuration generated using defined blocks. This user configuration is produced on a personal computer in the STEP M (BG) language, loaded into the module via a serial interface, and stored in an EEPROM.

This principle enables the implementation of highly flexible, individual concepts on the modules for process-oriented preprocessing with direct intervention into the process whilst bypassing the automation system. Likely applications are e.g. balanced backup structures or particularly time-critical process operations.

An example of a configurable signal module is the analog input module 6DS1 731-8RR for temperature signals. The required data on the type of transmitter, measuring range, cold junction etc. must be defined by configuring for the input channels (max. 32, basic module and 2 extension modules). The configuring data for this module are stored in a flash-PROM. The STRUK-AS 220 EA program is required for loading/configuring (see page 4/6).

I/O modules from other systems

I/O modules from other systems can be operated on the I/O bus of an AS 235 automation system via existing parallel and serial links (see Section 7).

The following modules can be connected:

• SIMATIC S5-115U digital and analog input/output modules, fitted in ER 701-1 and ER 701-2 expansion racks

• SIMATIC S5-135U/155U digital and analog input/output modules, fitted in EU 183U, EU 184U and EU 187U expansion units

• Digital and analog input/output modules of the ET 100U electronic terminator

The respective interface module for the coupling occupies one I/O slot.

These modules are addressed via the driver blocks for analog and binary input/output which are present as standard in the AS 235 automation system. The analog drivers are equipped with special, parameterizable operating modes for SIMATIC S5 modules. Limit monitoring functions in the driver software are used for measured-value monitoring functions which are missing on the SIMATIC S5 modules or which operate with limits other than those common in the TELEPERM M system.

Communication between TELEPERM M and SIMATIC S5/S7 automation systems is possible using the coupling module 6DS1 333-8AB (page 7/8) and the 3964 R/RK 512 procedure.

Selection criteria for I/O modules

There are various criteria for selecting the most suitable I/O modules for a particular application; these criteria must be evaluated depending on the respective application. The selection of either TELEPERM M or SIMATIC S5 modules is made easier for the planning engineer by the following decision criteria:

• Preprocessing on the module Only signal modules from the SIMATIC S5 range without preprocessing (non-intelligent) can be used.

• 230 V peripherals In contrast to TELEPERM M, the range of SIMATIC S5 modules also contains input/output modules for signals up to 230 V.

• Backup response In the event of a fault in the automation system, a fault in the coupling, or faults in the expansion unit, SIMATIC modules always enter the safety status (0 V, 0 mA), whereas the planning engineer can select for the TELEPERM M output modules whether the last value is to be retained or whether the safety value is to be output.

• Transmitter and measuring range monitoring The monitoring functions for measuring range limits which are not present in the SIMATIC S5 modules to the same extent as in the TELEPERM M modules are implemented in the special operating modes of the driver blocks in the automation system so that they are also available when using SIMATIC S5 modules.

Power supply, earthing

The different earthing concepts of the two systems must be observed when using TELEPERM M automation systems and SIMATIC S5 expansion units together. An automation system is always part of a so-called "0-V island" which is earthed via a single connection to the central earthing point (with the central 24-V supply). In the SIMATIC S5 expansion unit, the each module is directly connected to the frame and via this to the local earth.

In the case of coupling between TELEPERM M automation systems and SIMATIC S5 expansion units, it must be ensured that the screen of the connection cable does not destroy the earthing concept of TELEPERM M. Isolating power supply units must be used in the expansion unit, or DC 24 V/DC 24 V converters with electrical isolation must be provided if necessary.

Lightning protection with distributed configuration

The use of SIMATIC S5 modules in distributed, serially-coupled EU expansion units makes it possible to protect the transmission lines using appropriate overvoltage arresters.

Function modules

Function modules have their own functions which are independent of the central unit. They possess backup modes which permit operation independent of the central unit.

Some of the function modules are configurable. The firmware of these configurable modules contains an interpreter which pro- cesses a user configuration made up of defined blocks. This user configuration is generated on a personal computer using the STEP M (BG) programming language, loaded into the module via a serial TTY interface, and stored in an EEPROM. The STRUK-AS 220 EA program is used as the configuring aid for this purpose (see page 4/9).

• S closed-loop control module, two-channel, configurable,

6DS1 411-8RR

Configuring

STRUK-AS 220 EA configuring program

STRUK-AS 220 EA can be used to configure the configurable I/O modules on a programming device/PC (with MS-DOS operating system). The programming device/PC must be connected

• via a built-in TTY interface and the cable 6DS8 170-8AD to the TTY interface of the I/O module (direct coupling) or alternatively

• integrated via a local bus interface module N-AT and a cable for 20-m local bus into the CS 275 plant bus (central coupling).

Special requirements for module configuring via the CS 275 plant bus:

• AS 235 system software version G.1 or later

• Vacant user memory (RAM) at least 300 byte (memory is made available again following configuring).

The complete configuration including all application parameters can be stored on diskette and thus loaded into a replacement module if necessary. New settings, and the associated possibility of making mistakes, are therefore unnecessary. The replacement module is immediately ready for use.

PBT 65 process operation keyboard

The 4 authorization stages have the following meaning:

• S tage 1: keyboard "OFF", no operation possible

• S tage 2: process operation keyboard "ON"

• S tage 3: configuring keyboard "ON"

• S tage 4: configuring keyboard and process operation key-

board "ON".

A 4-digit password which can be individually modified is assigned to each authorization key. The last authorization stage selected is automatically present when the PBT 65 process operation keyboard is switched on. Transfer to a different authorization stage is only possible if the appropriate password is known. The authorization stage set is indicated by a yellow LED integrated in the corresponding key.

Test mode

The PBT 65 process operation keyboard has an integrated test mode. The test functions include initialization and deletion of the LCD, EPROM, LED, LCD, RAM, interfaces, testing of the authorization memory, and resetting of passwords.

PBT 65 process operation keyboard

The PBT 65 process operation keyboard is used:

• To enter operating data

• For process operations (modification of operating modes, values and statuses)

• To select area, group and loop displays

• To acknowledge messages and horn alarms.

It is possible to connect an additional configuring keyboard.

Design

The PBT 65 process operation keyboard consists of a desktop housing with

•dust-proof and slash-proof touch pad keyboard,

• LCD unit and

• keyboard electronics.

At the rear there are connections for the configuring keyboard, the automation system and the DC 24 V power supply.

In order to achieve the degree of protection IP 65, it is neces- sary to protect the rear connections against dust, splashing and gases. A keyboard attachment i

s available for this purpose as an IP 65 kit. Without this kit, the process operation keyboard corresponds to the degree of protection IP 20.

The two-row LCD unit of the process operation keyboard can display 40 characters in each line. The top line is used for mes- sages, the bottom line for the variable inscription of the 8 keys located below it. The background can be illuminated if neces- sary. The background illumination is automatically switched off if no operations are made for a longer period of time.

Mode of operation

The functions of the process operation keyboard are enabled in 4 authorization stages and selected using authorization keys identified by key switch symbols and a password.

Mini floppy disk unit

The mini floppy disk unit is required for booting, loading and archiving the RAM contents of an AS 235 using floppy disks.

The mini floppy disk unit is a desktop unit with 3-m long connection cables for data transmission and power supply.

The data media are 5.25" floppy disks, double sided, high density (DS-HD).

Mode of operation

The drive interface of the mini floppy disk unit is matched to the central processing unit by the interface module. The data are exchanged sector by sector by direct memory access (DMA). This ensures rapid data access and little loading on the central processor.

Since the drive of the mini floppy disk unit is not equipped with a head load function, the read/write head always rests on the floppy disk when the drive is locked using the lever. To prevent high wear and possible damage to the read/write head or the floppy disk during permanent operation, the lever should either be opened immediately following an archiving or loading procedure, or the floppy disk should be removed.

The AS 235, AS 235 H and AS 235 K automation systems are connected together and to other automation systems and operator systems of the TELEPERM M process control system via the CS 275 bus in medium-sized and large plants.

Central process control is carried out using the OS 525 and WinCC/TM-OS operator systems. SIMATIC PC or other AT-compatible personal computers, PG programming devices and computers from other manufacturers can be connected to the bus system for higher-level tasks.

Sequential transfer of data between the individual participants is in time-division multiplex mode. Participants within a local area or a cabinet group are connected over distances of up to 20 m by a local bus. A remote bus connects distributed systems over distances of up to 4 km.

A redundant design of the bus line increases of the availability of the CS 275 plant bus. The remote bus network can be extended to a maximum length of 3 x 4 km using bus couplers.

Local range

4 line signals are used in the local range. The data are transmitted sequentially on one data line. A second line transmits the clock, the third is used for synchronization. The fourth line is required to switch over data transmission to channel A or B of the redundant local bus. The wired-OR technique is used with the local bus for coupling.

The interface modules for the local bus have a redundant local bus interface. They are connected together with one cable in which the local bus is redundant.

The max. length of the local bus cable is 20 m.



Design

The CS 275 bus system consists of

• a local bus which is always redundant and

• a remote bus which can be either of single or redundant

design.

If e.g. automation systems are to be connected together via a local bus, the following are required for

interface modules for 20-m local bus

•

participants:

(cf. table on page 6/5)

•

-1 cables 6DS8 201-8..

• 1 front plug 6DS9 200-8AA. 2 interface modules N-AS are required for the AS 235 H system.

These are handled as one participant, i.e. the same bus address is set on both interface modules.

Up to nine CS 275 modules can be coupled together as a local bus island via the 20-m local bus. If this local bus island is connected to the remote bus, each of the bus converters UI (max.

2) is also counted as a participant (cf. Figs. 6/3 and 6/4). The cable connectors are provided at one end with a front plug

for connection to the interface module for 20-m local bus, the other end of the cable is prepared for the connection and is soldered to the front plug of the next interface module. Only one front plug is required for the n-th local bus participant. This is soldered to the free end of the cable. The single front plug is not required with an additional remote bus coupling. It is replaced in this case by the front plug of the cable 6DS8 204-8.., 6DS8 205-8.., 6DS9 201-8CA or -8FC.

With a remote bus connection, the AS 235 H is always delivered with a cable 6DS9 201-8FC with 5 plugs instead of a combination of two connecting cables (6DS8 204-8../6DS9 201-8CA + 6DS8 201-8..).

The cable 6DS8 205-8.. with two plugs can be used for the pointto-point connection of two local bus participants as an alternative to the combination of cable 6DS8 201-8.. and front plug.

Local bus cables which have to be routed more than 2.5 m out of cabinets must be laid in a separate, screened/earthed cable duct.

The various interface modules for 20-m local bus are listed in the following table. Catalog PLT 130 contains a detailed description of the individual modules.

Remote range

Transmission takes place via a coaxial cable at distances up to 4 km. The coupling to the remote bus is non-reactive.

Remote and local buses can be connected by bus converters. In this way, individual AS or OS systems or groups located in one area and connected by a local bus can exchange information with more distant individual systems or groups. The complete plant bus carries the same information.

Two autonomous plant buses are connected together via a bus coupler so that only the information intended for the other bus is transferred.

Single remote bus

An AS 235 or AS 235 K system is connected to a single nonredundant remote bus via the interface module for 20-m local bus N-AS and a bus conductor UI. Two coupled interface modules N-AS are used in the AS 235 H system.

A cable 6DS8 205-8MB is required in this case with the AS 235 K system. This is provided with 2 front plugs for connection to the interface module N-AS and the bus converter UI. The connection distributor AV is omitted in the AS 235 K.

The cable 6DS8 204-8.. with 3 plugs is used for the single remote bus with the AS 235, and connects the N-AS to the bus converter UI and the connection distributor AV. An alternative is the cable 6DS9 201-8CA with 4 plugs which is provided for the redundant remote bus. One plug remains unused in this case until a redundant design is made if required.

The AS 235 H is also provided with the cable 6DS9 201-8FC with 5 plugs for a single remote bus connection. This connects both N-AS modules to the bus converter UI and the connection distributor AV. One plug remains initially unused. An alternative is a combination of cables 6DS8 204-8.. and 6DS8 201-8.. .

A connector board AF "Remote bus" is required to connect the remote bus cable. The coaxial cable connection to the connector board AF has a fixed connection to the bus converter.

Connection distributor AV

The connection distributor AV (Order No. 6DS9 207-8AA) has a vacant plug connection to the redundant 20-m local bus for the connection of configuring aids (e.g. personal computer with the PROGRAF AS+ engineering tool). It must be connected to the local bus via a cable for this purpose.

Bus converter Ul

A bus converter is required to connect individual participants or a local bus with several participants to a remote bus. It performs continuous signal conversion between the local bus and the remote bus or vice versa without intermediate storage. The coupling is inductive and non-reactive.

Possible locations:

• AS 235 and AS 235 H basic cabinet

• AS 235 K basic system

• Remote bus connection unit

• Bus coupler

• Remote bus connection subrack. See Catalog PLT 130 for detailed information on the bus con-

verter.

Connector board AF "Remote bus"

The remote bus cable is connected to the bus converter via the connector board AF "Remote bus". The board is provided with a terminating resistor which can be activated using a jumper. The resistor is activated in the first and last bus participants.

Overvoltage protection

The participants connected to the remote bus can be extensively protected against destruction by overvoltages by means of the coarse and fine overvoltage protection units.

The coarse protection limits high-voltage signals of high power to the arc voltage. The coarse protection is able to handle brief peaks in the kA range. It is installed where the remote bus enters the building. The fine protection reduces the residual voltage which passes the coarse protection down to a value between the internal conductor and the screen of the remote bus cable which is harmless for the amplifier of the inductive coupler in the bus converter. The fine protection is fitted on the connector AF.

The transmission rate and thus the cycle time can be varied with a serial coupling. However, the selected data transfer rate has an influence on the maximum distance which can been covered.

The driver blocks required for the various links are contained in the standard software of the automation system.

This section only deals with direct coupling. The summary table lists all available interface modules for cou-

pling with other systems, together with the most important features of the modules.

All interface modules are operated in a slot for I/O modules. An important feature for differentiation is the type of coupling

(parallel/serial):

• With a parallel coupling, the interface module 6DS1 321-8AA

transfers all bus signals between the automation system and the coupling partner – with the exception of the level conversion signals TTL-RS 422-TTL – in real-time mode. The driver blocks directly access the I/O modules in the connected expansion unit with a parallel coupling.

• With a serial coupling, the interface module

s themselves han-

Coupling of other systems

The interface module 6DS1 333-8AB can be used to couple other systems (e.g. scales, data acquisition units, process chromatographs) if the system has an appropriate interface, i.e. 20-mA current loop interface (TTY) and 3964 R / RK 512 procedure. Other procedures and protocols require especially produced firmware. However, detailed knowledge of the module hardware, the interface to the automation system, and the driver blocks is required in this case.

We would be pleased to recommend software companie appropriate know-how for the generation of this firmware.

dle the data transfer with the coupling partner. Data transfer is via the transfer RAM of the interface module with a serial coupling.

When selecting the interface module suitable for the respective application, the following factors may be important in addition to the type of coupling partner:

• The distance to the coupling partner

• The topology of the system

• The earthing concept

• Measures which may be needed for lightning protection. Since the parallel coupling is not electrically isolated and the

RS 422 system used permits a maximum difference of 7 V between the earth potentials of the coupling partners, it is recommendable to use a serial coupling for longer distances within buildings and for links between different buildings. As a result of the lower number of conductors in the cable and the electrical isolation, this facilitates any protection measures

for static and

dynamic differences in potential (earthing, lightning protection).

The SIMATIC S5-115U I/O modules provide the user of the TELEPERM M process control system with a further comprehensive range of I/O modules for optimizing the field connections.

Of major advantage is that signal voltages up to 250 V can be used with these I/O modules, and that the coupling level otherwise required with TELEPERM M can be omitted. However, intelligent SIMATIC S5 I/O modules are not suitable for operation on AS 235 automation systems.

The following are required to couple the AS 235 automation sys- tems to SIMATIC S5-115U I/O modules in the ER 701 subrack for

extension units:

• Interface module for

SIMATIC S5 expansion units 6DS1 321-8AA

• CC/EU interface module IM 310 6ES5 310-3AB11

• Terminator 6ES5 760-0AA11 An ER 701 subrack can be directly connected via each of the

two channels of interface module 6DS1 321-8AA. Further central or distributed expansion units can be connected to this (see Catalog ST 50). The number of SIMATIC S5 I/O modules which can be coupled to an interface module is limited, however, by the maximum addressing volume of 2 x 256 bytes (256 bytes per channel).

Notes:

cannot

• An ER 701-3 subrack

be used instead of the ER 701-2.

• The first half of the address area of each channel of the inter-

face module (128 bytes) is reserved for digital inputs and outputs and must not be used for analog inputs and outputs.

Up to 6 interface modules 6DS1321-8AA with a total of 12 usable channels can be operated per AS 235 automation system.

The interface module can be inserted into any slot for I/O modules of an AS 235 automation system or ES 100 K extension sys- tem. The module has two bit-parallel RS 422 interfaces via which direct access (without intermediate storage) is possible to the SIMATIC S5 I/O modules. The CC/EU interface module IM 310 is used for the coupling at the SIMATIC end. This is inserted into slot 7 of the ER 701-2 subrack for extension units.

Max. 2.5 m

(central coupling)

The maximum distance between the interface module 6DS1 321-8AA and the last expansion unit is 500 m with a dis- tributed coupling.

Data transfer between the central processing unit of an A automation system and the SIMATIC S5-115U I/O models is han- dled by the driver blocks AA and AE for analog values and the drivers A110 and E 110 for binary values.

The maximum permissible difference in the

potential between

the AS 235 automation system and the expansion unit is 7 V.

SIMATIC S5-135U/155U I/O modules

The SIMATIC S5-135U/155U I/O modules provide the user of the TELEPERM M process control system with a further comprehensive range of I/O modules for optimizing the field connections.

The following are required to couple the AS 235 automation sys- tems to SIMATIC S5 I/O modules of compact design in EU 183U expansion units:

• Interface module for

SIMATIC S5 expansion units 6DS1321-8AA

• Connecting cable 721 6ES5 721-0..

• CC/EU interface module IM 310 6ES5 310-3AB11

• Terminator 6ES5 760-0AA11 An EU 183U expansion unit can be directly connected via each

of the two channels of interface module 6DS

1 321-8AA. Further EU 183U expansion units can be connected to this either centrally or distributed. EU 184U and EU 187U expansion units can only be connected centralized (see Catalog ST 50). The number of SIMATIC S5 I/O modules which can be coupled to an interface module is limited, however, by the maximum addressing volume of 2 x 256 bytes (256 bytes per channel).

Note: An EU 185U or EU 186U expansion unit cannot be used instead of the EU 183U. The EU 185U / EU 186U are only partially suitable for coupling. They can only be used if they are directly operated as the only unit without central expansion.

Up to 6 interface modules 6DS1321-8AA with a total of 12 usable channels can be operated per AS 235 automation system.

The interface module can be inserted into any slot for I/O modules of an AS 235 automation system or ES 100 K extension sys- tem.

The module has two bit-parallel RS 422 interfaces via which direct access (without intermediate storage) is possible to the SIMATIC S5-135U/155U I/O modules. The CC/EU interface module IM 310 is used for the coupling at the SIMATIC end. This is inserted into slot 3 of the EU 183U expansion unit.

The maximum distance between the interface module 6DS1 321-8AA and the last expansion unit is 500 m with a dis- tributed coupling.

Data transfer between the central processing unit of an AS 235 automation system and the SIMATIC S5-135U/155U I/O modules is handled by the driver blocks AA and AE for analog values and the drivers A110 and E 110 for binary values.

The maximum permissible difference in the

potential between

the AS 235 automation system and the expansion unit is 7 V.

Interface module for SIMATIC S5 expansion units

The interface module 6DS1 321-8AA is a compact subassembly, double height (2 standard slots). The module has:

• 2 bas e plugs for

– I/O bus interface, 48-contact male connector – Power supply, 64-contact male connector

• 2 parallel interfaces for connection of expansion units of the

S5-115U, S5-135U and S5-155U programmable controllers to SIMATIC S5 I/O modules, 50-contact front plugs in each case

Mode of operation

The interface module 6DS1 321-8AA enables direct, parallel read/write operations on the I/O modules of the S5-115U, S5-135U and S5-155U programmable controllers without intermediate storage. It matches the I/O bus of the TELEPERM M process control system to that of SIMATIC S5.

The TTL levels of the TELEPERM M I/O bus are converted into

symmetrical levels of the R

S 422 interface.

The addressing volume of 2 x 256 bytes for I/O modules of the S5-115U, S5-135U and S5-155U programmable controllers is

mapped in the I/O addressing volume of 4 Kbyte of the AS 235/ AS 235 K/AS 235 H automation systems. This means that a TELEPERM M address is assigned to each SIMATIC S5 address.

In certain cases it may be advantageous to assign autonomous parts of an automation program to a subordinate automation level. There is less loading on the automation system, and valuable calculation time can be saved. This is especially important in the case of automation tasks with short cycle times which may place a heavy loading on the calculation capacity of a proces- sor. Subordinate programs can also be developed and tested independently of other program sections.

The following are required to couple the AS 235, AS 235 H and AS 235 K automation systems to SIMATIC S5-115U, S5-135U and S5-155U central controllers and SIMATIC S7-300 and S7-400 automation systems:

6ES7 441-2AA02-0AE0

The interface module 6DS1 333-8AB can be inserted into any slots for I/O modules of an AS 235 automation system or an ES 100 K extension system. A SIMATIC S5/S7 central controller can be connected to each of its 2 channels.

A screened, four-conductor cable twisted in pairs is used for data transmission. The maximum distance between the interface module and the central controller is 1000 m. Data transfer is sequential via a coupling link with 20-mA current loop. The channel-specific transmission rate can be adjusted in steps:

Tran smission rate Max. coupling line length 300, 600, 1200, 2400 bits/s 4800 bits/s 9600 bits/s

1000 m 500 m 300 m

Data transfer between the AS 235 central processing unit and the interface module 6DS1 333-8AB is handled via the S5KS and S5KE driver blocks in the automation system. The 3964 or 3964 R transmission procedure (selectable) is used for data transmission between the interface module and the SIMATIC S5/S7 central controller.

RK 512 is used as the protocol. The SIMATIC S5 sends or fetches the data by means of messages. The TELEPERM M interface module is the passive participant in the communication. S7 central controllers operate with SEND/RECEIVE and S5 analog-value format.

Interface module for SIMATIC S5/S7 central controllers

The interface module for SIMATIC S5/S7 central controllers, 6DS1 333-8AB, is a double-height compact subassembly. The front panel width is 30.48 mm (2 standard slots). The module has 2 base plugs for the I/O bus interface and two serial interfaces for connection of a SIMATIC-S5/S7 central controller.

Mode of operation

The data arriving in parallel via the I/O bus of the automation sys- tem are stored cyclically in the transfer memory (RAM) of the interface module for SIMATIC S5/S7 central controllers. The SIMATIC S5 central controllers can read the transfer memory using fetch messages. The transmitter section of the interface module reads the data from the transfer memory, supplements them into a complete message, and output

s this via the serial

interface to the SIMATIC S5/S7 central controller. Messages transmitted by the SIMATIC S5/S7 central controller

are tested for reliability in the receiver section of the interface module, and the data contained in them are stored in the transfer memory. The automation system cyclically reads these data from the transfer memory.

The SIMATIC S5 I/O modules and the ET 100U electronic terminator provide the user of the TELEPERM M process control sys- tem with two further comprehensive ranges of I/O modules for optimizing the field connections.

Binary and analog input/output modules can be connected:

• I/O modules of the SIMATIC S5-115U programmable controller I/O modules which can be connected in the ER 701-2 or

ER 701-3 expansion racks (cf. page 7/4):

• I/O modules of the SIMATIC S5-135U and S5-155U programmable controllers

I/O modules which can be connected in the EU 183U, EU 185U or EU 186U expansion units (cf. page 7/6):

• ET 100U electronic terminator

The ET 100U electronic terminator (see Catalog ST 50) enables direct connection of transmitters, final control elements, valves and lamps in the immediate vicinity of the process. Cabling and assembly costs can be greatly reduced by the omission of junction boxes and as a re

sult of the serial two-wire connection to the

programmable controller. Digital and analog I/O modules with intrinsically-safe inputs and

outputs are available for the connection of devices in potentially explosive atmospheres.

• The IM 318-3 interface module (6ES 5 318-3UA11) in the expansion units; the adapter casing 6ES5 491-0LB11 in addition with the 701-2 expansion subrack.

The interface module 6DS1 327-8AA has 2 connections with 1 plug for 2 lines. Up to 32 devices can be connected in any sequence to each connection. Up to 3 interface modules 6DS1 327-8AA are permissible per AS 235 automation system.

A line may be up to 3000 m long up to the last device. However, the distances which can be covered depend on the type of cable used and the selected transmission rate.

Interface module for ET 100U

The interface module for ET 100U, 6DS1 327-8AA, is a doubleheight compact subassembly. The front panel width is 30.48 mm (2 standard slots).

The module has 2 base plugs for the I/O bus interface and the power supply, as well as a front plug (4-contact male connector) with screw terminals for lines 1 and 2.

ET 100U electronic terminators, ER 701-2 and ER 701-3 expansion racks and EU 183U, EU 185U and EU 186U expansion units can be connected to each line in any order. The total cable length up to the last device must not exceed 3000 m.

The front panel of the interface module has a slot for inserting a configuration EPROM submodule. This is required when connecting ET 100U electronic terminators.

Mode of operation

Up to 3 interface modules 6DS1 327-8AA can be inserted into any I/O bus slots in an AS 235 automation system. Each module occupies

The interface modules adapt the I/O bus interface to the serial SIMATIC S5 interface. In this manner, analog and digital input/ output modules of the ET 100U electronic terminator or the S5-115U, S5-135U and S5-155U programmable controllers can be connected to an AS 235 automation system.

If SIMATIC analog input modules are used, linearization of the characteristic and compensation of the cold junction temperature must be carried out by the user for non-linear transmitters and thermocouples.

Following application of the supply voltage after briefly switching off the mode switch on the module and following elimination of an interruption in the transmission cable on one of the two lines, the interface module carries out a configuration operation in which it stores an image of the connected SIMATIC S5 peripheral devices and used I/O modules in its main memory.

The configuration data for the connected SIMATIC S5 expans units are determined by reading the configuration lists in the expansion units, and for the ET 100U electronic terminator by scanning the configuration EPROM submodule generated by the user. The configuration data are the reference data for the interface module.

The AS 235 automation system communicates with the SIMATIC S5 peripheral devices via an intermediate memory on the interface module. Both the automation system and the processor of the interface module store transfer data in this memory.

The processor of the interface module cyclically processes the connected SIMATIC S5 I/O modules, transfers the output data entered by the automation system to the SIMATIC S5 output modules and updates the input area in the intermediate memory by scanning the SIMATIC S5 input modules.

Data transfer between the interface module and the SIMATIC S5 peripheral devices initiative always originates in the interface module.

The data are protected by 1 or 2 test bytes depending on the set transmission rate (cyclic BGH code).

If a plug on any SIMATIC S5 device is disconnected, the trans- mission line to the other devices is not interrupted (party line).

Ordering information

Individual components/options and complete systems

When ordering, a differentiation must be made between individual components/options (e.g. I/O modules, printers) and complete systems (AS 235 standard configurations defined by ordering units).

All individual components/options are subject to individual testing. With complete systems, the interactions of the individual components in the system network is proven in a system test.

Ordering of complete systems (AS 235 standard configuration)

Complete systems can be configured from a selection of defined, functionally divided ordering units, and ordered using an Order No. (e.g. 6DS2 124-7CC31-0D). The scope of delivery of such AS 235 standard configurations coded in the second and third blocks of the Order No. is reproduced exactly in the component li additions of type "But without ..." is therefore impossible.

The complete systems defined by an Order No. can be supplemented or modified by additional options. Operation of the options into the system test of the complete system must be agreed upon separately.

Ordering of options

When ordering options, a differentiation must be made between "Options with assembly" and "Options without assembly".

The options with Order No. and quantity must be listed in the order. Please enclose additional information required for order processing in the form of arrangement, designation and connection diagrams.

• Options with assembly "Options with assembly" comprise mechanical components,

connection elements, modules or devices which can be fitted in the cabinet and wired and labelled if necessary, including side panels and partitions.

The customer-specific designation and wiring of cabinet connection elements SAE 32, the coding and insertion of I/O modules, and the inscription of subracks necessitate additional data when ordering (arrangement, designation and connection diagrams). If, for example, appropriate data for the I/O modules is mi assembly".

• Options without assembly "Options without assembly" are loosely supplied mechanical

components, connection elements, modules or devices, e.g. input/output devices, connecting cables or also side panels and partitions if these are to be assembled on site.

When ordering input and output devices and their connecting cables, we recommend that you enclose an arrangement diagram.
