Synchronisation

Tip!

By means of the CAN_Synchronization SB, the internal time base of the PLC can be synchronised
with the arrival of the sync telegram.

Thus the internal calculating processes (e. g. control oriented processes) of the PLC can be
synchronised with the calculating processes of other nodes which can also process the sync
telegram.

Detailed information on the CAN_Synchronization SB can be found in chapter 7.7.
