3.7 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.

3.7.1 CAN sync response
The response to the reception of a sync telegram can be configured via C0366:
Code LCD
Possible settings
IMPORTANT
Lenze Selection
C0366 Sync response 1 CAN sync response
0 No response No response
1 Response to sync PLC responds to a sync telegram
by sending the CAN1_OUT object.
3.7.2 CAN sync identifiers
The transmission or reception identifiers of the sync telegram can be configured via C0367/C0368:
Code LCD
Possible settings
IMPORTANT
Lenze Selection
C0367 Sync Rx Id 128 1 {1} 256 CAN sync Rx identifier
Receive identifier of the sync
telegram
C0368 Sync Tx Id 128 1 {1} 256 CAN sync Tx identifier
Transmit identifier of the sync
telegram
3.7.3 CAN sync Tx transmission cycle
The cycle time within which a sync telegram with the identifier set in C0368 is transmitted can be
configured via C0369:
Code LCD
Possible settings
IMPORTANT
Lenze Selection
C0369 Sync Tx time 0 0 {1} 65000
0 = Off
CAN sync transmission telegram
cycle
A sync telegram with the identifier
of C0368 is sent with the set cycle
time.
