The reason why the issue occurs is because the signature of the Unity application that was used to
create the 'Variables' table for the PLC service in the 'Factroycast HM'I application, does not match the
signature of the Unity application in the PLC. Whenever a logic or configuration change is made to the
Unity application in the PLC, the signature also changes.
