Comments

The ITcPostCyclicCaller interface is implemented by TwinCAT tasks. A module uses this interface to login its ITcPostCyclic interface to a task, usually as the last initialization step in the SafeOP to OP transition. After login, the PostCycleUpdate() method of the module instance is called. The interface is also used to log off the module so that it is no longer called by the task.
