Communication Error (Group)
Beckhoff · TwinSAFE Logic FB
¿Qué significa GROUP Value 2 ?
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.
Causas comunes
- Disruption of the EtherCAT network communication to one or more TwinSAFE terminals (e.g., EL6900 module at Address 1002).
- Broken or loose EtherCAT cable connection (e.g., RJ45 connector at port X02 on EL69x0) causing loss of FSoE (Fail-Safe over EtherCAT) messages.
- Incorrect FSoE network configuration, such as mismatched connection IDs or an excessively short FSoE watchdog time (e.g., P7-03).
- Internal hardware fault within a TwinSAFE I/O module (e.g., EL1957, EL2904) preventing it from participating in FSoE communication.

- 1
1. Check the EtherCAT network diagnostics in TwinCAT System Manager for topology errors, lost frames, or disconnected devices.
- 2
2. Inspect all EtherCAT patch cables and connectors in the safety network segment for damage or secure connections.
- 3
3. Verify the FSoE connection watchdog time parameter (e.g., P7-03) and connection IDs for consistency across all TwinSAFE devices.
- 4
4. Power cycle the affected TwinSAFE modules (e.g., EL69x0, EL1957) and the EtherCAT coupler.

5. Ensure the EtherCAT master is stable and not experiencing its own communication issues (e.g., network adapter driver problem).
