1.4 Beckhoff Identification Code (BIC)

The Beckhoff Identification Code (BIC) is increasingly being applied to Beckhoff products to uniquely identify the product. The BIC is represented as a Data Matrix Code (DMC, code scheme ECC200), the content is based on the ANSI standard MH10.8.2-2016.
Fig.1: BIC as data matrix code (DMC, code scheme ECC200)
The BIC will be introduced step by step across all product groups.
Depending on the product, it can be found in the following places:
• on the packaging unit
• directly on the product (if space suffices)
• on the packaging unit and the product
The BIC is machine-readable and contains information that can also be used by the customer for handling and product management.
Each piece of information can be uniquely identified using the so-called data identifier (ANSIMH10.8.2-2016). The data identifier is followed by a character string. Both together have a maximum length according to the table below. If the information is shorter, spaces are added to it. The data under positions 1 to 4 are always available.

Further types of information and data identifiers are used by Beckhoff and serve internal processes.
Structure of the BIC
Example of composite information from item 1 to 4 and 6. The data identifiers are marked in red for better display:
BTN
An important component of the BIC is the Beckhoff Traceability Number (BTN, item no.2). The BTN is a unique serial number consisting of eight characters that will replace all other serial number systems at Beckhoff in the long term (e.g. batch designations on IO components, previous serial number range for safety products, etc.). The BTN will also be introduced step by step, so it may happen that the BTN is not yet coded in the BIC.
NOTE
This information has been carefully prepared. However, the procedure described is constantly being further developed. We reserve the right to revise and change procedures and documentation at any time and with­out prior notice. No claims for changes can be made from the information, illustrations and descriptions in this information.

Basic Function Principles

4 Basic Function Principles

The analog input terminals
• KL3444 and KL3448 process signals in the range between 0 and 20mA
• KL3454 and KL3458 process signals in the range between 4 and 20mA
with a resolution of 12bits (4095 steps). They can supply the sensors from voltage fed in via the power contacts. The power contacts can optionally be supplied via the standard supply or via a power feed terminal with electrical isolation.
Process data output format
In the delivery state the process data are shown in two's complement form (integer -1 corresponds to 0xFFFF). Other presentation types can be selected via the feature register R32 (e.g. signed amount representation, Siemens output format).

5 Mounting and wiring

5.1 Instructions for ESD protection

NOTE
Destruction of the devices by electrostatic discharge possible!
The devices contain components at risk from electrostatic discharge caused by improper handling.
• Please ensure you are electrostatically discharged and avoid touching the contacts of the device directly.
• Avoid contact with highly insulating materials (synthetic fibers, plastic film etc.).
• Surroundings (working place, packaging and personnel) should by grounded probably, when handling with the devices.
• Each assembly must be terminated at the right hand end with a KL9010 bus end terminal, to ensure the protection class and ESD protection.
Fig.10: Spring contacts of the Beckhoff I/O components

5.2 Installation on mounting rails

WARNING
Risk of electric shock and damage of device!
Bring the bus terminal system into a safe, powered down state before starting installation, disassembly or wiring of the bus terminals!
Mounting and wiring
Assembly
Fig.11: Attaching on mounting rail
The bus coupler and bus terminals are attached to commercially available 35mm mounting rails (DIN rails according to EN60715) by applying slight pressure:
1. First attach the fieldbus coupler to the mounting rail.
2. The bus terminals are now attached on the right-hand side of the fieldbus coupler. Join the compo­nents with tongue and groove and push the terminals against the mounting rail, until the lock clicks onto the mounting rail. If the terminals are clipped onto the mounting rail first and then pushed together without tongue and groove, the connection will not be operational! When correctly assembled, no significant gap should be visible between the housings.
Fixing of mounting rails
The locking mechanism of the terminals and couplers extends to the profile of the mounting rail. At the installation, the locking mechanism of the components must not come into conflict with the fixing bolts of the mounting rail. To mount the mounting rails with a height of 7.5mm under the terminals and couplers, you should use flat mounting connections (e.g. countersunk screws or blind rivets).
KL3444, KL3448, KL3454 und KL345822 Version: 3.2.0
Mounting and wiring
Disassembly
Fig.12: Disassembling of terminal
Each terminal is secured by a lock on the mounting rail, which must be released for disassembly:
1. Pull the terminal by its orange-colored lugs approximately 1cm away from the mounting rail. In doing so for this terminal the mounting rail lock is released automatically and you can pull the terminal out of the bus terminal block easily without excessive force.
2. Grasp the released terminal with thumb and index finger simultaneous at the upper and lower grooved housing surfaces and pull the terminal out of the bus terminal block.
Connections within a bus terminal block
The electric connections between the Bus Coupler and the Bus Terminals are automatically realized by joining the components:
• The six spring contacts of the K-Bus/E-Bus deal with the transfer of the data and the supply of the Bus Terminal electronics.
• The power contacts deal with the supply for the field electronics and thus represent a supply rail within the bus terminal block. The power contacts are supplied via terminals on the Bus Coupler (up to 24V) or for higher voltages via power feed terminals.
Power Contacts
During the design of a bus terminal block, the pin assignment of the individual Bus Terminals must be taken account of, since some types (e.g. analog Bus Terminals or digital 4-channel Bus Termi­nals) do not or not fully loop through the power contacts. Power Feed Terminals (KL91xx, KL92xx or EL91xx, EL92xx) interrupt the power contacts and thus represent the start of a new supply rail.
PE power contact
The power contact labeled PE can be used as a protective earth. For safety reasons this contact mates first when plugging together, and can ground short-circuit currents of up to 125A.
Mounting and wiring
Fig.13: Power contact on left side
NOTE
Possible damage of the device
Note that, for reasons of electromagnetic compatibility, the PE contacts are capacitatively coupled to the mounting rail. This may lead to incorrect results during insulation testing or to damage on the terminal (e.g. disruptive discharge to the PE line during insulation testing of a consumer with a nominal voltage of 230V). For insulation testing, disconnect the PE supply line at the Bus Coupler or the Power Feed Terminal! In or­der to decouple further feed points for testing, these Power Feed Terminals can be released and pulled at least 10mm from the group of terminals.
WARNING
Risk of electric shock!
The PE power contact must not be used for other potentials!

5.3 Installation instructions for enhanced mechanical load capacity

Overview
The Bus Terminal system offers different connection options for optimum adaptation to the respective application:
• The terminals of ELxxxx and KLxxxx series with standard wiring include electronics and connection level in a single enclosure.
• The terminals of ESxxxx and KSxxxx series feature a pluggable connection level and enable steady wiring while replacing.
• The High Density Terminals (HD Terminals) include electronics and connection level in a single enclosure and have advanced packaging density.
Standard wiring (ELxxxx / KLxxxx)
Fig.14: Standard wiring
The terminals of ELxxxx and KLxxxx series have been tried and tested for years. They feature integrated screwless spring force technology for fast and simple assembly.
Mounting and wiring
Pluggable wiring (ESxxxx / KSxxxx)
Fig.15: Pluggable wiring
The terminals of ESxxxx and KSxxxx series feature a pluggable connection level. The assembly and wiring procedure is the same as for the ELxxxx and KLxxxx series. The pluggable connection level enables the complete wiring to be removed as a plug connector from the top of the housing for servicing. The lower section can be removed from the terminal block by pulling the unlocking tab. Insert the new component and plug in the connector with the wiring. This reduces the installation time and eliminates the risk of wires being mixed up.
The familiar dimensions of the terminal only had to be changed slightly. The new connector adds about 3 mm. The maximum height of the terminal remains unchanged.
A tab for strain relief of the cable simplifies assembly in many applications and prevents tangling of individual connection wires when the connector is removed.
Conductor cross sections between 0.08mm2 and 2.5mm2 can continue to be used with the proven spring force technology.
The overview and nomenclature of the product names for ESxxxx and KSxxxx series has been retained as known from ELxxxx and KLxxxx series.
High Density Terminals (HD Terminals)
Fig.16: High Density Terminals
The Bus Terminals from these series with 16 terminal points are distinguished by a particularly compact design, as the packaging density is twice as large as that of the standard 12mm Bus Terminals. Massive conductors and conductors with a wire end sleeve can be inserted directly into the spring loaded terminal point without tools.
Wiring HD Terminals
The High Density (HD) Terminals of the ELx8xx and KLx8xx series doesn't support pluggable wiring.
Ultrasonically "bonded" (ultrasonically welded) conductors
Ultrasonically “bonded" conductors
It is also possible to connect the Standard and High Density Terminals with ultrasonically "bonded" (ultrasonically welded) conductors. In this case, please note the tables concerning the wire-size width below!

Terminals for standard wiring ELxxxx/KLxxxx and for pluggable wiring ESxxxx/KSxxxx
Fig.17: Connecting a cable on a terminal point
Up to eight terminal points enable the connection of solid or finely stranded cables to the Bus Terminal. The terminal points are implemented in spring force technology. Connect the cables as follows:
1. Open a terminal point by pushing a screwdriver straight against the stop into the square opening above the terminal point. Do not turn the screwdriver or move it alternately (don't toggle).
2. The wire can now be inserted into the round terminal opening without any force.
3. The terminal point closes automatically when the pressure is released, holding the wire securely and permanently.

KS2000 Configuration Software

6 KS2000 Configuration Software

6.1 KS2000 - Introduction

The KS2000 configuration software permits configuration, commissioning and parameterization of bus couplers, of the affiliated bus terminals and of Fieldbus Box Modules. The connection between bus coupler/ Fieldbus Box Module and the PC is established by means of the serial configuration cable or the fieldbus.
Fig.21: KS2000 configuration software
Configuration
You can configure the Fieldbus stations with the Configuration Software KS2000 offline. That means, setting up a terminal station with all settings on the couplers and terminals resp. the Fieldbus Box Modules can be prepared before the commissioning phase. Later on, this configuration can be transferred to the terminal station in the commissioning phase by means of a download. For documentation purposes, you are provided with the breakdown of the terminal station, a parts list of modules used and a list of the parameters you have modified. After an upload, existing fieldbus stations are at your disposal for further editing.
Parameterization
KS2000 offers simple access to the parameters of a fieldbus station: specific high-level dialogs are available for all bus couplers, all intelligent bus terminals and Fieldbus Box modules with the aid of which settings can be modified easily. Alternatively, you have full access to all internal registers of the bus couplers and intelligent terminals. Refer to the register description for the meanings of the registers.
KL3444, KL3448, KL3454 und KL345834 Version: 3.2.0
KS2000 Configuration Software
Commissioning
The KS2000 software facilitates commissioning of machine components or their fieldbus stations: Configured settings can be transferred to the fieldbus modules by means of a download. After a login to the terminal station, it is possible to define settings in couplers, terminals and Fieldbus Box modules directly online. The same high-level dialogs and register access are available for this purpose as in the configuration phase.
The KS2000 offers access to the process images of the bus couplers and Fieldbus Box modules.
• Thus, the coupler's input and output images can be observed by monitoring.
• Process values can be specified in the output image for commissioning of the output modules.
All possibilities in the online mode can be used in parallel with the actual fieldbus mode of the terminal station. The fieldbus protocol always has the higher priority in this case.
KS2000 Configuration Software

6.2 Parameterization with KS2000

Connect the configuration interface of your Fieldbus Coupler with the serial interface of your PC via the configuration cable and start the KS2000 Configuration Software.

• Please refer to the Mapping [}44] page for the assignment of the bytes and words to the addresses of the controller.
• The meaning of the control and status bytes is explained in Control and status bytes.
• In process data mode the analog values are transferred in input data words DataIN1 to DataIN4. Output data words DataOUT1 to DataOUT4 are not used.
KL3408 and KL3468 as well as KL3448 and KL3458
KL3408 and KL3468 as well as KL3448 and KL3458 represent a special case with regard to the process image: Essentially, two four-channel terminals are accommodated in one terminal housing, which behave like two terminals for the K-bus.
Each of these eight channel analog terminals has the same process image like two four channel terminals of same signal type, plugged next to each other. The KS2000 configuration software and the TwinCAT System Manager display them like two separate four channel analog terminals.
Special treatment for 8-channel analog terminals
Regarding K-bus diagnosis for your Bus Coupler (e.g. for flashing codes, error code and error argu­ment), note that these eight channel analog terminals are represented as two four channel terminals from a Bus Coupler perspective. If the Bus Coupler is the fault location in the event of an error, you must count each eight channel analog terminal as two terminals!
Access from the User Program

7.2 Mapping

The Bus Terminals occupy addresses within the process image of the controller. The assignment of process data (input and output data) and parameterization data (control and status bytes) to the control addresses is called mapping. The type of mapping depends on:
• the fieldbus system used
• the terminal type
• the parameterization of the Bus Coupler (conditions) such as
◦ compact or full evaluation
◦ Intel or Motorola format
◦ word alignment switched on or off
The Bus Couplers (BKxxxx, LCxxxx) and Bus TerminalControllers (BCxxxx, BXxxxx) are supplied with certain default settings. The default setting can be changed with the KS2000 configuration software or with a master configuration software (e.g.TwinCAT System Manager or ComProfibus).
The following tables show the mapping depending on different conditions. For information about the contents of the individual bytes please refer to the pages Process image and Control and status byte.
Compact evaluation
For compact evaluation, the analog input terminals only occupy addresses in the input process image. Control and status bytes cannot be accessed.

7.5 Register description

The following registers are used to parameterize the KL3444, KL3448, KL3454 and KL3458. Each signal channel of the analog terminal has one register that can be read or written to with the aid of control, status
and data bytes [}43] via register communication.
R0: Raw value A/D-C Raw value of the A/D converter (XR)
R6: Diagnostic register The status byte is mapped to the low-order byte (bit 7 to bit 0) of register R6. The high-order byte (bit 15 to bit 8) of register R6 is reserved.
R7: Command register The command register of KL3444 and KL3454 is currently not used.
R8: Terminal description Register R8 contains the terminal identifier. e.g.:
◦ KL3444: 0x0D74 (3444
◦ KL3454: 0x0D7E (3454
R9: Firmware version Register R9 contains the ASCII coding of the terminal's firmware version, e.g. 0x3141 (1A) corresponds to the ASCII character '1' and '0x41' to the ASCII character 'A'. This value cannot be changed.
R10: Data length (multiplex shift register) R10 contains the number of multiplexed shift registers and their length in bits.
R11: Signal channels Unlike R10, this contains the number of channels that are logically present. Thus for example a shift register that is physically present can perfectly well consist of several signal channels.
R12: Minimum data length The particular byte contains the minimum data length for a channel that is to be transferred. If the MSB is set, the control and status byte is not necessarily required for the terminal function and is not transferred to the control, if the Bus Coupler is configured accordingly.

dec
)
R31: Code word register
◦ If you write values into the user registers without first entering the user code word (0x1235) into
the code word register, the terminal will not accept the supplied data.
◦ If you write values into the user registers and have previously entered the user code word
(0x1235) in the code word register, these values are stored in the RAM registers and in the SEEPROM registers and are therefore retained if the terminal is restarted.
The code word is reset with each restart of the terminal.

7.6 Examples of Register Communication

The numbering of the bytes in the examples corresponds to the display without word alignment.

7.6.1 Example 1: reading the firmware version from Register 9

Output Data
Byte 0: Control byte Byte 1: DataOUT1, high byte Byte 2: DataOUT1, low byte
0x89 (1000 1001
Explanation:
• Bit 0.7 set means: Register communication switched on.
• Bit 0.6 not set means: reading the register.
• Bits 0.5 to 0.0 specify the register number 9 with 00 1001
• The output data word (byte 1 and byte 2) has no meaning during read access. To change a register, write the required value into the output word.
Input Data (answer of the bus terminal)
Byte 0: Status byte Byte 1: DataIN1, high byte Byte 2: DataIN1, low byte
0x89 0x33 0x41
) 0xXX 0xXX
bin
.
bin
Explanation:
• The terminal returns the value of the control byte as a receipt in the status byte.
• The terminal returns the firmware version 0x3341 in the input data word (byte 1 and byte 2). This is to be interpreted as an ASCII code:
◦ ASCII code 0x33 represents the digit 3
◦ ASCII code 0x41 represents the letter A
The firmware version is thus 3A.
Access from the User Program

7.6.2 Example 2: Writing to an user register

Code word
In normal mode all user registers are read-only with the exception of Register 31. In order to deacti­vate this write protection you must write the code word (0x1235) into Register 31. If a value other than 0x1235 is written into Register 31, write protection is reactivated. Please note that changes to a register only become effective after restarting the terminal (power-off/power-on).
I. Write the code word (0x1235) into Register 31.
Output Data
Byte 0: Control byte Byte 1: DataOUT1, high byte Byte 2: DataOUT1, low byte
0xDF (1101 1111
Explanation:
• Bit 0.7 set means: Register communication switched on.
• Bit 0.6 set means: writing to the register.
• Bits 0.5 to 0.0 specify the register number 31 with 01 1111
