Comments
The ITcCyclic interface is implemented by TwinCAT modules. This interface is passed to the ITcCyclicCaller::AddModule() method when a module logs on to a task, usually as the last initialization step in the transition from SafeOP to OP. After login, the CycleUpdate() method of the module instance is called.
