CANSync (CAN bus synchronisation)
Function
By means of this function block, the internal time base of the controller can be
synchronised with the instant of reception of the sync telegram or a terminal signal.
Thereby the start of cyclical 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 in a synchronuous manner.
