Figure 6-2 Overview Of The Synchronization Points - Siemens Simatic S7-1500 Function Manual

Synchronization points
A synchronization point always exists before inputs are read in, for example at the cycle
control point or at the beginning of a cyclic OB.

Trigger freeze state
To trigger the freeze state, following modes are available for the virtual controller:
● SingleStep operating modes
See Synchronize simulation partner cycle-controlled (Page 78).
● TimespanSynchronized operating modes
See Synchronize simulation partner time-controlled (Page 80).
In Default operating mode, the virtual controller does not change into a freeze state.
