Communication Error (Group)
Beckhoff · TwinSAFE Logic FB
What does GROUP Value 2 mean?
At least one TwinSAFE connection within the EL/EJ69x0 group is faulty. This implies a disruption or loss of communication between safety devices or across the EtherCAT network for safety-relevant data. This will prevent safe operation and necessitate immediate investigation of network integrity, as safety communication is compromised.
Additional Steps
Steps 1–2 are listed in Priority Fix.
- 3
Inspect the status LEDs on the EL/EJ69x0 group module and all associated EtherCAT slaves for communication error indicators.
- 4
Ensure all safety devices involved in the connection are powered on, functional, and correctly addressed on the network.
- 5
Restart the EtherCAT master and relevant slave devices if necessary, after confirming no underlying physical issues exist.
