Baud rate
The Bus Coupler features automatic baud rate detection. When the supply voltage is switched on, the Bus
Coupler searches for the current baud rate and stores it as long as the supply voltage is present.
Note
Restarts the bus coupler for automatic baud rate detection
If the master baud rate is changed, the Bus Coupler has to be switched off and on again in
order to restart automatic baud rate detection.

Overview
Configuration types
The Bus Terminal controllers of the BCxx50, BCxx20 and BXxx00 series can be configured in two different
ways: DEFAULT CONFIG or TwinCAT CONFIG.
DEFAULT-CONFIG
Bus Terminals are mapped in the order they are inserted, i.e. first the complex Bus Terminals followed by the
digital Bus Terminals.
The complex Bus Terminals are mapped as follows:
• Word Alignment
• complex representation
CAUTION
The process image depends on the connected terminals!
The process image changes when a terminal is added or removed!
The data of the fieldbus slaves interface are referred to as PLC variables. The PLC variables have
addresses from %QB1000 and %IB1000
The DEFAULT CONFIG (without PLC program) can also be used for writing and testing of the Connected
Bus Terminals. To this end, the Bus Terminal Controller must be scanned in the System Manager, and
FreeRun mode must be enabled (to use this function, no PLC program may be active on the Bus Terminal
Controller).
TWINCAT-CONFIG
In the TwinCAT CONFIG the Bus Terminals and PLC variables can be freely linked as required (TwinCAT
System Manager file required). The configuration is transferred to the coupler via the System Manager
and ADS.
The following is required for the TwinCAT configuration (TC file):
• Via the fieldbus (PROFIBUS, CANopen, Ethernet)
PROFIBUS: (BC3150, BX3100)
◦ PC with FC310x from version 2.0 and TwinCAT 2.9 build 1000
◦ BX3100 with CIF60 or CP5412
