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.
