Module Fault (Group)
Beckhoff · TwinSAFE Logic FB
What does GROUP Value 3 mean?
The 'ModuleFault' input for the EL/EJ69x0 group is active (set to 1). This indicates a general fault detected by the safety module itself, possibly a hardware issue, internal diagnostic failure, or a critical input signal indicating a module problem. The group will enter an ERROR state, preventing safe operation.
Complete Troubleshooting Guide
- 1
Check the diagnostic LEDs on the EL/EJ69x0 module for specific fault indicators; consult the module manual for LED interpretations.
- 2
Review the module's documentation for potential causes of a 'ModuleFault' input being active (e.g., internal error, watchdog timeout).
- 3
Verify the power supply voltage and current to the EL/EJ69x0 module; ensure it is within specified limits.
- 4
If no clear external cause is found and all connections are verified, consider replacing the EL/EJ69x0 module after backing up its configuration.
