T5BusIec850s: connection loss during command execution (Operate received but not responded yet) locks next commands

T5BusIec850s: connection loss during command execution (Operate received but not responded yet) locks next commands

Summary

Issue in the IEC 61850 Server driver in zenon Logic: if an 850-client disconnects right after requesting Operate and before the IEC 61850 Server sends the response, the state-machine is locked in Control Variable = 199 (or 200). If the 850-client reconnects, the driver refuses all command-write requests to affected object.
