Cause : FBA B communication comes when cyclical communication between supply unit and fieldbus adapter module B or between PLC and fieldbus adapter module B is lost.
- Check status of fieldbus communication. See user documentation of fieldbus interface.
- Check settings of parameter group 150 FBA, 154 FBA B settings, 155 FBA B data in and 156 FBA B data out.
- Check cable connections.
- Check if communication master is able to communicate.
