Tip!
Detailed information on CAN synchronisation and configuration via codes can
be found in the chapter 8.6 "Axis synchronisation (CAN synchronisation)"
((
¶ 166).
This SB serves to synchronise the internal time base of the controller with the instant of
reception of the sync telegram or a terminal signal. Thereby the start of cyclic and
time−controlled internal processes of all controllers involved in the synchronisation (e.g.
data transfer from tasks to the DCTRL function block) is effected synchronously.
