I reproduced the behaviour of the PLC on beckhoffSim. This reproduces the same behaviour seen in the tunnel devices (devices hang).

Implemented the fix and verified the correct behaviour with beckhoffSim.

Fixes will be verified next Monday with the tunnel system.

Have a nice weekend

ps: For future reference:

beckhoffSim  tags/1.1.0-1.4  (implements the recent plc behaviour (framework tag N/A Could not find tobias))

beckhoffDevices tags/2.0.1-1.4 hangs
