Error Diagnostics

Diagnostic signaling of the F I/O module not a safety-related feature
Diagnostic signaling of the F I/O module cannot be part of the safety function
under any circumstances.
After detecting internal or external errors, the F I/O module outputs diagnostic
messages to the safe PLC via the fieldbus. Errors can be identified by the
diagnostic messages, and appropriate troubleshooting measures can be taken.
The F I/O module provides diagnostic messages via the indicators and the
diagnostic services of the PROFINET fieldbus system.
All diagnostic messages that the F I/O module makes available are listed below
in alphabetical order. The structure of the diagnostic messages is described in
the fieldbus coupler manuals.
The F I/O module 753-661/000-004 can be operated on the WAGO I/O
System 750 fieldbus couplers specified in section "Technical Data" > ... >
