What causes the error 'Requested programmer connect mode is not available. Do you wish to use monitor mode instead? PLC is already reserved by entity: EMPTY' when trying to connect to an M340 with Unity Pro.

This was once a recurring issue that was addressed with the V2.1 firmware release. Make sure that the M340 is at V2.1 firmware or higher.
