Deactivation n: The deactivation bit assigned to task n.
If the bit is set via SINUMERIK Operate or from the PLC user program, the current state of task n is frozen and no longer

TRUE: Task deactivated
FALSE: Task active
This means it is possible, for example, to adapt the maintenance interval according to the actual runtime of the modules.
