TwinCAT Sync Clock
Synchronization of Simulink® simulation with local system time.

Block Parameter

Sync Clock Mode | |
---|---|
None | Simulation is neither accelerated nor decelerated. |
Clock | Simulation time and system time are synchronized. |
ClockWithTime | Simulation time and system time are synchronized. In addition, an output port is created that displays the past system time. |
ClockWithTimeAndDeviation | Simulation time and system time are synchronized. In addition, an output port is created that shows the past system time and the deviation between simulation time and system time. |
Comment
The block does not synchronize the Simulink® simulation with the TwinCAT runtime, but with the local system time. Synchronization of the local system time is done by "braking" the Simulink® simulation; acceleration is not possible.
For a fully synchronized software-in-the-loop simulation between TwinCAT and Simulink® you need a TwinCAT 3 Usermode Runtime: External Control and the SiL Connector Block in Simulink®.
