AlStatusCode 0x1B : Sync manager watchdog
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.
