System Description

2.1.2 Coupler/Controller (1)

The Coupler/Controller forms the link between the fieldbus and the field devices with their I/O functions. All control functions required for the faultless operation of the I/O functions are carried out by the Coupler/Controller. The connection to different fieldbus systems is established by each of the corresponding Coupler/Controller, e.g. for PROFIBUS, INTERBUS, CAN, MODBUS etc. In this way a change of the fieldbus system is possible.

The programmable fieldbus controller 750-833 combines the PROFIBUS DP functionality of the fieldbus coupler 750-333 with the functionality of a Programmable Logic Control (PLC). Programming of the application is done with WAGO-I/O-PRO in accordance with IEC 61131-3, covering all 5 programming languages. The programmer can access all fieldbus and I/O data.

Characteristics and use of the Controllers:

• The use of decentralized control can better support a PLC or PC

• Signal pre-processing reduces fieldbus transmissions

• Complex applications can be divided into multiple tasks

• Tasks can be prioritized

• Peripheral equipment can be controlled directly, resulting in faster system

response times

• Programmable response in the event of a fieldbus failure

• Simple, self-sufficient control

2.1.3 I/O Modules (2)

In the I/O modules, the incoming process data is converted. Corresponding to the different requirements, special I/O modules are available for a variety of functions. There are digital and analog inputs and outputs and modules for special functions (Counter modules, Terminal blocks for encoder and resolvers and communication modules).

2.1.4 End Module (3)

A End Module is needed for faultless operation of the node. The termination module is always placed as the last module in order to obtain a termination of the fieldbus node. This module has no I/O function.

Installation

2.2 Installation

2.2.1 Safty notes

ESD (Electrostatic Discharge) The modules are equipped with electronic components which may be destroyed by electrostatic discharge.When handling the modules, ensure that the environment (persons, workplace and packing) is well grounded. Avoid touching conductive components, e.g. gold contacts.

Attention

Switch off the system prior to working on bus modules!

2.2.2 Mechanical Installation

All system components can be snapped directly on a carrier rail in accordance with the European standard EN 50022 (DIN 35).

Attention

Ensure that the carrier rail is fastened with countersunk head screws or blind rivets as the snap-on foot of the I/O components extends onto the carrier rail.

The installation is simple and space saving. All modules have the same shape to minimize the project commitment.

The reliable positioning and connection of the coupler and the individual I/O modules is made using a tongue and groove system. Due to the automatic locking, the individual components are securely seated on the rail after installing.

Installation

Self-cleaning power jumper contacts conduct the supply voltage for the field side. They are located on either side of the modules. The female contacts on the right-hand side of the fieldbus coupler and the bus modules are designed as spring contacts to protect against accidental contact. Male contacts are located on the left-hand side of the bus modules.

Fig. 2-4: Power Jumper Contacts g01xx00d

Danger

The power contacts are sharp-edged. Handle the module carefully to prevent injury.

Pos. 1

Pos. 2

Attention

Please take into consideration that some bus modules have no or only some power jumper contacts. The design of some modules does not physically allow assembly them in rows as the grooves for the male contacts are closed at the top.

The data contacts are designed as self-cleaning gold spring contacts which automatically produce a secure connection.

Fig. 2-5: Data contacts p0xxx07x

Warning

Do not connect the I/O module to gold spring contacts in order to avoid soiling or scratches!

2.3 Electrical Installation

2.3.1 Wire Connection

Conductors with a cross section of 0.08 to 2.5 mm² (AWG 28-12) can be connected using a CAGE CLAMP connection to achieve a vibration resistant, fast and maintenance free connection. To actuate CAGE CLAMP enter an actuation tool in the opening above the connection. Following this, enter the conductor in the corresponding opening. The conductor is clamped securely with the removal of the actuation tool.

Electrical Installation

Fig. 2-6: Inserting conductor end p0xxx06x

The clamping force adjusts automatically to the cross section. The full surface of the CAGE CLAMP pressure is applied against the conductor without damaging it. Conductor deformation is compensated for and self-loosening is avoided. The transition point between the conductor and the CAGE CLAMP

is protected against corrosive influences. The connection can be made quickly and is also maintenance free, saving the costs for a periodic checking of terminal connections.

Two carrier rail contacts responsible for the electrical contact between the grounded carrier rail and the controller, are fitted underneath the coupler/controller.

Attention

Ensure a perfect contact point between carrier rail contacts and carrier rail. The carrier rail must be grounded.

1 – Power supply System 2 – Power supply Field-side

The power supply on the field side is electrically isolated from the system supply. In this manner sensors and actuators can be supplied and fused by a separate voltage source.

If a non-regulated power supply is used for the coupler/controller electronics 24 V voltage supply , it must be filtered through a capacitor (200 µF per 1 A load current). To this effect a back-up capacitor module (Order-No. 288-824) was developed for the WAGO-I/O-SYSTEM. This module serves to regulate a noisy 24 V DC voltage supply, to keep the ripple voltage within specified limits. The cause for these fluctuations could be a voltage interruption on the primary side, a secondary side overload or the switching of ”non quenched“ inductance or capacitance.

Warning

The supply modules + and – which are permanently integrated on the buscouplers, can be supplied with 24 V DC only. 120 V AC and 230 V AC can only be supplied via modules 750-609, 750-611 and 750-612!

Warning

The ground (earth) field side contact should be disconnected when testing the isolation. Otherwise the results could be wrong or the module could be destroyed.

WAGO-I/O-SYSTEM 750 D R A F T PROFIBUS 2001-02-27

Power supply

2.4.1 System supply voltage

The system supply voltage (24 V DC) is filtered with a voltage regulator before powering the coupler electronics as well as to the internal bus. Electrical isolation from the external fieldbus system depends on the type of Coupler/Controller.

The internal bus includes the internal communication between the coupler/controller and the bus modules as well as the power supply for the bus modules. The power supply is limited to a maximum value. This value depends on the type of Coupler/Controller. If the sum of the internal power consumption of all bus modules exceeds this value, it is necessary to add additional internal system supply modules (Order-No. 750-613).

The control electronics in the bus modules are powered by snap-fit mounting the bus modules using the internal bus contacts. A reliable contact is assured by the gold plated, self cleaning slide contacts. The removal of a bus module will cause an interruption in communication to the following bus modules. The coupler/controller identifies the interruption point and displays a corresponding fault message.

Warning

Removing or inserting the I/O modules with the voltage applied can lead to undefined conditions. For this reason only undertake work on the I/O modules when isolated from the power supply!

D R A F T WAGO-I/O-SYSTEM 750

2001-02-27 PROFIBUS

2.4.2 Supply Voltage Field Side

The voltage is automatically supplied when the I/O modules are snapped together. Self-cleaning power jumper contacts (P.J.C.s) ensure safe connections. The current capacity of the power contacts is 10 A max.

The PE contact is a preceding ground (earth) contact corresponding to the standards which can be used as a protective earth. The contact has a leakage capacity of 125 A.

Warning

Produce a low impedance connection from the carrier rail to the PE contact point in the switch cabinet.

Attention

Depending on the I/O function, some modules do not have P.J.C.s. It is important to note this when assembling a node. Many modules require field side power, many do not. Please review the circuit diagrams of the individual modules. An additional power supply module may be necessary. Refer to the individual terminal/module data sheets!

WAGO-I/O-SYSTEM 750 • 15

Power supply

When adding a power supply module, the field supply is always interrupted at the power contacts. From this point a new power supply is made, which can also include a potential change. This feature guarantees a high degree of system flexibility.

3.1.1 Description

The fieldbus coupler 750-333 displays the peripheral data of all I/O modules in the WAGO-I/O-SYSTEM 750 on PROFIBUS DP.

In the initialisation phase the bus coupler determines the physical structure of the node and creates a process image from this with all inputs and outputs. I/O modules with a bit width smaller than 8 can be combined to form one byte in order to optimise the address space.

In addition the possibility exists to deactivate projected I/O modules. In this manner the physical structure of the node can be individually designed with regard to the peripheral signals, without undertaking any changes to an already existing control application.

The diagnosis concept is based on an identification and channel based diagnosis in accordance with EN 50170. Thus it is not necessary to program modules for the evaluation of manufacturer specific diagnosis information.

The station address (decimal) is determined using two rotary switches on the electronic module.

ADDRESS

Fig. 3-5: Setting the station address g012102d

The switch „x1“ determines the units position of the address. The switch „x10“ determines the tens positions of the address. Valid station addresses are between 1 and 99. The coupler also permits the station address 0.

The station address is taken over by the fieldbus coupler after switching on the device (initialisation phase). Adjustments of the switch have no effect during operation.

3.1.2.6 Configuration interface

The configuration interface used for the communication with WAGO-I/OCHECK or for firmware upload is located behind the cover flap.

3.1.3 Operating system

Following the configuration of the master activation and the electrical installation if the fieldbus station can start up the system.

After switching on the supply voltage the coupler performs a self test of all functions of its devices, the I/O module and the fieldbus interface. Following this the I/O modules and the present configuration is determined, whereby an external not visible list is generated. This list includes an input and an output area on which is represented the fieldbus RAM of the protocol chip.

In the event of a fault the coupler changes to the "Stop" condition. The "I/O" LED flashes red. After a fault free start up the coupler changes to the "Fieldbus start" status and the "I/O" LED lights up green.

3.1.4 Process image

3.1.4.1 Local process image

After switching on, the coupler recognises all I/O modules plugged into the node which supply or wait for data (data width/bit width > 0). In nodes analog and digital I/O modules can be mixed.

Note

For the number of input and output bits or bytes of the individually activated on I/O modules please refer to the corresponding I/O module description.

The coupler produces an internal process image from the data width and the type of type of I/O module as well as the position of the I/O modules in the node. It is divided into an input and an output data area.

The data of the digital I/O modules is bit orientated, i.e. the data exchange is made bit for bit. The analog I/O modules are representative for all byte orientated I/O modules, i.e. those where the data exchange is made byte for byte. These I/O modules include for example the counter modules, I/O modules for angle and path measurement as well as the communication modules.

The data of the I/O modules is separated for the local input and output process image in the sequence of their position after the coupler in the individual process image.

Note

A process image restructuring may result if a node is changed or extended. In this case the process data addresses also change in comparison with earlier ones.

D R A F T WAGO-I/O-SYSTEM 750

2001-02-27 PROFIBUS

3.1.4.2 Allocation of the input and output data

The process data is exchanged via the PROFIBUS with the higher ranking controls (master). A maximum of 128 bytes of data is transmitted from the master to the coupler or from the node to the output data. The coupler responds by returning a maximum of 128 bytes input data to the master.

Modules are configured when projecting the node which can be taken over from a hardware catalogue of the configuration programs. The information covering the possible modules is contained in the GSD files.

The coupler generates an internal mapping in accordance with the installed and configured settings of the node, in which the allocation of the input and output data is determined in the local process image with the position in the PROFIBUS DP Telegram.

3.1.5 Configuration

The configuration of the node is performed in accordance with the physical requirements of the fieldbus coupler and I/O modules.

The fieldbus coupler or the process data channel is to be configured on the first slot. The other slots are configured in accordance with the physical requirements of the I/O modules. Here only I/O modules with process data are relevant. The supply modules without diagnosis, bus internal system supply module and the termination module are to be ignored for the configuration because they do not provide any process data.

One or tow modules are entered in the hardware catalogue for each I/O module. The module appear as 750-xyz ..., for example 750-400 2 DI/24 V DC/3.0

For all binary modules an addition is made to the entry *750-xyz .... When us-

ing these denominations the coupler adds the binary information to the current

module in a byte which was previously opened with 750-xyz .... The use of a

„*“ module is only permitted when the number of channels is less than or equal to the remaining bits in the previously opened byte. The binary I/O modules combined in a byte can be arranged at separate locations, i.e. binary I/O modules with a different signal type or also byte orientated I/O modules can be connected between.

In order to be able to individually arrange the scope of connected periphery units independent of the control program, it is possible to parameterise I/O modules in the configuration table as „not connected“. In this manner process data still present is filtered for the individual module and not transferred on the PROFIBUS DP to and read by the periphery units.

3.1.5.1 GSD files

Under PROFIBUS DP the features of the modules are defined by the manufacturers in the form of a GSD file (unit basic data).

Structure, content and coding of this unit main data are standardised and made available to the user allowing to project optional DP slaves using the project units of various manufacturers.

Further information

The PNO provides information about the GSD files of all listed manufacturers.

3.1.8 Configuration and parameterisation of I/O modules

3.1.8.1 Digital I/O modules

All binary I/O modules contain parameterisation information extended by 3 bytes, to serve, amongst others, for identification on the internal bus and the structure of the mapping table. With diagnosis capable terminals the diagnosis message can be suppressed or released for a channel or module. Binary outputs offer the alternative to switch to parameterisable substitute values in the case of a master failure.

Note

For simplification the tables only show the article number for the module designation. The module „750-400“ thus corresponds to the module „750-400 2 DI/24 V DC/3.0 ms“

1. The "I/O" LED generates a fault display with the first blink sequence (approx. 10 Hz).

2. The first pause is followed by the second blink sequence (approx. 1 Hz). The "I/O" LED blinks four times and thus signals the fault code 4 (internal bus data fault).

3. The third blink sequence follows the second pause. The "I/O ERR" LED blinks twelve times. The fault argument 12 means that the internal bus is interrupted after the 12 I/O module.

3.1.11 Fault behaviour

3.1.11.1 Fieldbus failure

A fieldbus failure has occurred when the master is switched off or the bus cable is interrupted. A fault in the master can also lead to a fieldbus failure.

The red "BF" LED lights up.

The failure of the fieldbus can activate the parameterisable substitute value of the I/O modules. During projecting of the inputs and outputs a substitute value can be laid down for each channel.

Fieldbus coupler / controller • 71

Fieldbus coupler 750-333

Substitute value strategy

Minimum value 0 0 or 4 mA, 0 V

Maximum value 1 20 mA, 10 V

Substitute value 0 or 1 0/4 ... 20 mA, -10 ... +10 V

Stop internal bus Behaviour determined by I/O module

Value (bit orientated) Digital output modules

Value (byte orientated) Analog output modules

The value is entered in the output process image by the coupler. With I/O modules with byte orientated data width, e.g. the pulse width module, the substitute value is determined via the value area.

As soon as the fieldbus is active the process data is transmitted and the output correspondingly set in the nodes.

72 • Fieldbus coupler / controller

Fieldbus coupler 750-333

3.1.11.2 Internal bus fault

An internal bus fault is created, for example, if an I/O module is removed. If this fault occurs during operation the output modules behave in the same manner as an I/O module stop. The input process image is set in accordance with the projected strategy.

The "I/O" LED blinks red. The slave generates a detailed fault message.

Once the internal bus fault has been overcome the coupler starts up automatically in accordance with the parameterised restart routine. The process data transfer is then restarted and the outputs reset in the nodes.

Fieldbus Controller 750-833

3.2.1 Description

The programmable fieldbus coupler 750-833 combines the PROFIBUS DPfunctions of the fieldbus coupler 750-333 with that of a programmable logic control (PLC). The application program is created with WAGO-I/O-PRO in accordance with IEC 61131-3. The programmer has access to all fieldbus and I/O data.

• Load relief for the central controls using decentral processing units

• Dividing complex applications into individual testable units

• Programmable fault reaction in the case of a fieldbus system failure

• Load relief of the communication system PROFIBUS DP by signal proc-

essing

• Reduction of reaction times by direct access to the periphery (without hav-

ing pass through the fieldbus system PROFIBUS DP)

• Autarcic smallest scale controls (station address 0)

• Use for decentral and central control

• Programmable in accordance with IEC 61131-3 in all 5 languages: IL, LD,

FBD, ST and SFC

In the initialisation phase the bus coupler determines the physical structure of the node and creates the process image of all inputs and outputs on this basis. I/O modules with a bit width of less than 8 can only be grouped to one byte in each case in order to optimise the address space.

It is also still possible to deactivate projected I/O modules. In this manner the physical structure of the node can be individually structured with reference to its periphery signals, without touching an already existing control application.

The diagnosis concept is based on the identification and channel based diagnosis in accordance with EN 50170. In this manner it is not necessary to program modules for evaluation of the manufacturer specific diagnosis information.

• Max. process data length 128 Byte (input and output process image)

• Automatic recognition of the transmission speed on the PROFIBUS of

9.6 kBd to 12 MBd

• All I/O modules from the WAGO-I/O-SYSTEM 750 are supported

• Configuration modules can be parameterised as wildcards.

• Parameterable substitute value for each channel

• D-Sub 9 pole bus connection

3.2.2.5 Station address

The station address is determined via two decimal rotary switches on the electronic module.

ADDRESS

x10

Fig. 3-16: Creating the station address g012102d

The switch „x1“ determines the unit position of the address. The switch „x10“ determines the tens position of the address. Valid station addresses lie between 1 and 99.

Fieldbus coupler / controller • 81

Fieldbus Controller 750-833

The station address is taken over by the fieldbus coupler after switching on the device (initialisation phase). Adjustments to the switch during operation have no effect.

Note

After Power-On the station address 0 causes the run-up of the controller and start of the PLC functions, without the fieldbus being active. Using this function an autarcic small scale control can be realised using the WAGO-I/O-SYSTEM 750

3.2.2.6 Configuration and programming interface

The configuration and programming interface is located behind the cover flap. This is used to communicate with WAGO-I/O-CHECK and WAGO-I/O-PRO as well as for firmware uploading.

The switch is a push/slide switch with 3 settings and a hold-to-run function.

From top to middle position Stop program processing (STOP)

(Lower position, bootstrap) (For original loading of firmware,

Push down (e.g with a screwdriver)

Hardware reset All outputs and flags are reset; variables are set to 0 or to FALSE or to an initial value.

The hardware reset can be performed with STOP as well as RUN in any position of the operating mode switch!

Attention

If outputs are set when switching over the operating mode switch from RUN to STOP they remain set! Switching off on the software side e.g. by initiators, are ineffective, because the program is no longer processed.

(An operating mode is internally changed at the end of a PLC cycle.)

Note

With "GET_STOP_VALUE" (library "System.lib") WAGO-I/O-PRO 32 provides a function which serves to recognise the last cycle prior to a program stop giving the user the possibility to program the behaviour of the controller in case of a STOP. With the aid of this function the controller outputs can be switched to a safe condition.

3.2.3 Operating system

3.2.3.1 Run-up

The controller runs-up after switching on the supply voltage or after a hardware reset. The PLC program in the flash memory is transferred to the RAM. The "I/O" LED flashes orange.

The controller then checks all functions of its modules in a self test, the internal bus and the fieldbus interface. Following this the I/O modules and the present configuration is determined. At the same time a list is generated which is not visible from outside. This includes an input and an output area, which shows on the fieldbus RAM of the fieldbus RAM. This is followed by the initialisation of the system. The variables are set to 0 or to FALSE or to an initialisation value given by the PLC program. The flags retain their status . The "I/O" LED blinks red during this phase.

Following a fault free run-up the controller changes over to the "Fieldbus start" mode. The "I/O" LED lights up green.

Fieldbus coupler / controller • 83

Fieldbus Controller 750-833

A PLC program does not yet exist in the flash memory when delivered. The controller runs-up as described, without initialising the system. It then behaves as a coupler.

3.2.3.2 PLC cycle

The PLC cycle starts following a fault free run-up when the operating mode switch is in the top position or by a start command from the WAGO-I/O-PRO

32. The input and output data of the fieldbus and the I/O modules as well as the times are read. Subsequently the PLC program in the RAM is processed followed by the output data of the fieldbus and the I/O modules in the process image. Operating system functions, amongst others, for diagnosis and communication are performed an the times actualised at the end of the PLC cycle. The cycle starts again with the reading in of the input and output data and the times.

The change of the operating mode (STOP/RUN) is made at the end of a PLC cycle.

The cycle time is the time from the start of the PLC program to the next start. If a loop is programmed within a PLC program the PLC running time and thus the PLC cycle are extended correspondingly.

The inputs, outputs and times are not updated during the processing of the PLC program. This actualisation occurs in a defined manner only at the end of the PLC program. For this reason it is not possible to wait for an event from the process or the elapse of a time within a loop.

3.2.4 Process image

3.2.4.1 Local process image

After switching on the controller recognises all I/O modules connected in the node, which are waiting for or transmitting data (data width/bit width > 0). In nodes analog and digital I/O modules can be fitted mixed.

Note

For the number of input and output bits or bytes of the individual switched on I/O modules please refer to the corresponding description of the I/O modules.

The controller generates an internal local process image from the data width and the type of I/O module as well as the position of the I/O modules in the node. This is divided into an input and an output area.

The data of the digital I/O modules are bit orientated, i.e. the data exchange is made bit by bit. The analog I/O modules are representative for all I/O modules which are byte orientated, in which the data exchange is also made byte by byte. These I/O modules also include, for example, counter modules, I/O modules for angle and path measurement as well as communication modules.

Fieldbus coupler / controller • 85

Fieldbus Controller 750-833

The data of the I/O modules is separated for the local input and output process image in the sequence of their position after the controller in the individual process image.

Note

If a node is changed or extended this may result in a new process image structure. In this case the process data addresses also change in comparison with earlier versions.

Fieldbus Controller 750-833

3.2.4.2 Allocation of the input and output data

The process data is exchanged via the PROFIBUS with the higher ranking controls (Master). A maximum of 128 byte of data is transmitted from the master to the controller, or node to the output data. The controller returns a maximum of 128 byte input data as a reply to the master.

The modules are configured when projecting the nodes. These modules can be copied from a hardware catalogue by the configurations programs. The information covering the possible modules is saved in the GSD files.

The controller generates an internal mapping in accordance with the installed and configured settings of the node, in which the allocation of the input and output data is determined in the local process image with the position in the PROFIBUS DP Telegram.

3.2.5 Configuration

The configuration of the node is performed in accordance with the physical requirements of the fieldbus controllers and I/O modules.

The fieldbus controller or the process data channel is to be configured on the first slot. The other slots are configured in accordance with the physical requirements of the I/O modules, whereby only I/O modules with process data are relevant. The supply modules without diagnosis, the supply modules without diagnosis, the bus internal system supply module and the termination module are to be ignored during configuration, as they do not provide any process data.

2 or 3 modules per I/O module are entered in the hardware catalogue. The modules appear as

750-xyz ..., e.g. 750-400 2 DI/24 V DC/3.0 ms. and PFC 750-xyz ..., e.g.. PFC 750-400 2 DI/24 V DC/3.0 ms.

The identification PFC 750-xyz ... states that the module concerned is exclusively processed by the internal control application. Its process data is not transmitted via the PROFIBUS-DP to the master or to the higher ranking controls.

Fieldbus coupler / controller • 87

Fieldbus Controller 750-833

Alos the entry *750-xyz .... is listed for all binary modules. When using this

identification the controller adds the binary information of the current module

in a byte previously opened with 750-xyz .... The use of a „*“ module is only

permitted when the number of channels is less or identical to the remaining bits in the previously opened byte. The binary I/O modules combined in a byte may be at different locations, i.e. binary I/O modules of a different signal type or byte orientated I/O modules can be connected between.

In order to configure the scope of the connected peripheries individually and independent of the control program, it is possible to parameter the I/O modules in the configuration table as „not plug fitted“. In this manner the process data still on the PROFIBUS DP can be filtered for the individual module and not transmitted to the periphery or read by it.

With the 750-833, after configuration of the connected periphery, the memory area is configured due to the variable arrangement of the fieldbus variables. For this the identification

1 byte PFC outputs, 2 byte PFC outputs to 64 byte PFC outputs

is available for the input image as well as

1 byte PFC inputs, 2 byte PFC inputs to 64 byte PFC inputs

for the output image.

By optionally combining the existing modules it is possible to project the required length on the fieldbus variables for PROFIBUS-DP.
