9.4.4 CAN objects
This tab shows you a list of the CAN process data objects (PDOs) to be transferred on the network,
which have been generated in the course of the compilation process.
Objects that have been created by means of a general circuit interconnection of devices, and objects
that have been constrained through deselection of the Automatic allocation control field are
displayed.
The list provides information about the process data objects which are transmitted via the selected
network:
Click the Linking of send and receive objects… button to open a dialog box that displays the linkage
of the sent and received process data objects in the tree structure. For purposes of a better
orientation, the transmission process data objects are sorted according to nodes.
