Fault behavior
WAGO-I/O-SYSTEM 750
BACnet/IP Controller
3.1.10.2 Internal Bus Error
An internal bus failure occurs, for example, if a bus module is removed. If the
error occurs during operation, the output modules operate as they do during an
internal bus stop.
The "I/O" LED flashes red.
The controller generates an error message (error code and error argument).
If the internal bus failure is resolved, the controller starts up after turning the
power off and on again as for a normal startup. The process data is transmitted
again and the outputs of the node are set accordingly.
