Error Code 0x001B

Meaning

Sync manager watchdog

Description

The slave did not receive process data within the specified watchdog time. Usually, the WD time is 100ms. The WD is re-started every time it receives new process data, usually when the Output SyncManager (SyncManager2) is written. For devices which have only inputs usually no WD is used. Increasing the WD is not a solution.

Reason: PLC stopped
