FECA-01 Communication Reinitialization Issue Technical Note

This document describes an issue where FECA-01 modules get stuck in the ERR SAFEOP INIT_ERR state after an EtherCAT communication link is disconnected and reconnected, requiring a reset of all IOs or the PLC to restore normal operation. The solution involves enabling the "Wait for WcState is OK" setting in TwinCAT advanced configuration for all FECA-01 modules, which prevents the error from recurring.
