My SAFEX C.12 is configured and running an application. However, on the EtherCAT bus, it constantly goes to Safe-OP with the diagnostic ' 0x001B: Sync manager watchdog'. If I command the bus to OP again, it reaches OP state but then goes into Safe-OP after a random amount of time. All other slaves on the bus are ok. This is a small application for STO outputs with some hardwired inputs. That is, no FSoE for this project. I cannot find a potential cause nor remedy for this situation.
