9.4.3 Synchronisation
You can use the Synchronisation tab to configure the necessary parameters in order to synchronise
the internal time base of selectable network nodes with the arrival of a so-called SYNC telegram.
You can also specify the node that is to send a SYNC object. The nodes that are to adapt their internal
control cycle to the sync object.
By this, the internal calculation processes (e. g. control-oriented processes) of a node can be
synchronised with the calculation processes of other nodes which can also process the SYNC
telegram.
SYNC source
SYNC receiver
In this list field select the nodes which are to synchronise to the SYNC telegram in the first column
by clicking the corresponding control fields.
• In the SYNC source group field the SYNC source with COB-ID and time interval is determined.
• In the SYNC receiver group field all nodes of the network are displayed in tabular form.
• The Appl. (*1) column indicates if, on the corresponding device, the process is to be
synchronised to the SYNC object. If no process can be synchronised tot he SYNC object on the
device, the respective cell will be inhibited.
• The PDO (*2) column indicates if the "Synchronised" transfer mode is available for a process
data object of this node.
