WAGO-I/O-SYSTEM 750
ETHERNET TCP/IP
Internal bus fault
More information
For detailed information to the Watchdog register see the Chapters "MODBUS
Functions"; "Watchdog (Fieldbus failure)" and "Watchdog Register".
When an internal bus fault occurs (e.g., an I/O module is removed), all output
modules turn off. Additionally, the "I/O" LED blinks red and generates a fault
message. This message is decoded from the blink code, in the form of a fault
code and fault argument.
Once the internal bus fault is fixed, the controller is restarted by cycling its
power. At this point the transfer of the process data resumes and the outputs
are updated.
