Synchronize simulation partner cycle-controlled

SingleStep operating modes
Several simulation partners (clients) are synchronized cycle-controlled with the SingleStep
operating modes of the virtual controller. The operating modes define the synchronization
point at which the virtual controller changes to the freeze state and sends the
OnSyncPointReached

In addition, the minimum cycle time of the OB 1 is overwritten in this operating mode. When you

define a minimum cycle time of 200 ms via the API, the minimum distance between two cycle con-
trol points is 200 virtual milliseconds. The default setting is 100 ms.
