GROUP Value 3

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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Verify the power supply voltage and current to the EL/EJ69x0 module; ensure it is within specified limits.

  2. 4

    If no clear external cause is found and all connections are verified, consider replacing the EL/EJ69x0 module after backing up its configuration.
