Laser Trumpf TruMark 3000 - the "TrunOff" command does not work (Opcon+ V2)

Hello.
I have a problem that we have built several times the same machine with the trumpf laser. On some machines the "Turn off" button works and on others it does not work.

Laser: Trumpf TruMark 3000 (Lasers are used older and rebuilt with new PC + EtherCAT card)

Peripheries: TruMark (1.1.12.0)

Object: Marking Laser (1.1.10.0)

 

The error will manifest itself as follows:

1)  Loc101V601_Laser.Unit.Command := MarkingLaserTrumpfCmd.LASER_OFF; Loc101V601_Laser.Unit.Execute := TRUE;

2) Laser receives no TLV command

3) Plc reports "Command timeout" error

All other commands work without problems.

 

Unfortunately I don't have the library source files to check why the TLV command is not being sent. Can someone please advise me what could be the error?
