BK4000 Interbus Coupler
The BK4000 Interbus Coupler maps the terminals in the delivery state with 2 bytes per channel:
• KL3202: 4 bytes of input data
• KL3224: 8 bytes of input data
Parameterization via the fieldbus is not possible. If the control and status byte is to be used, the KS2000
configuration software is required.

Further information about the mapping configuration of Bus Couplers can be found in the Appendix of the
respective Bus Coupler manual under Master configuration.
The Appendix contains an overview of possible mapping configurations depending on the parameters that
can be set.
NOTE
Parameterization with KS2000
The parameterizations can be carried out independently of the fieldbus system with the KS2000 configura-
tion software via the serial configuration interface in the Bus Coupler.
5.2
Mapping in the Bus Coupler
As already described in the
Terminal Configuration
section, each Bus Terminal is mapped in the Bus
Coupler. This mapping is usually done with the default setting in the Bus Coupler / Bus Terminal. The
KS2000 configuration software or a master configuration software (e.g. ComProfibus or TwinCAT System
Manager) can be used to change this default setting.
If the terminals are fully evaluated, they occupy memory space in the input and output process image.
The following tables provide information about how the terminals map themselves in the Bus Coupler,
depending on the parameters set.
Default mapping for: CANopen, CANCAL, DeviceNet, ControlNet, Modbus, RS232 and RS485 Coupler
