Synchronization Counter Init Value
This value is either set with the function ApiCmdSyncCounterSet() or if an RT receives a
synchronize mode code (MC1 or MC17). If MC1 is received by an RT, this value is reset to 0.
Note: The RT only modifies the synchronization counter on receiving a MC1 or MC17,
if the BC is not running!
