Installing CANopen devices:
As a precondition for mapping the CANbus hardware in the devices tree the
corresponding device descriptions must be installed via the Device Repository dialogs
on the local system. This concerns the description files (*.devdesc.xml) for the basic
modules CANbus and CANopen_Manager, which by default are provided with the
standard CANbus configuration plug-in, as well as the manufacturer-specific EDS-files
(Electronic Data Sheet) for the CANopen devices and modules which are used in the
bus system. These files each contain the parameter definitions and configuration
options of a module.
Basic hierarchy of a CANbus configuration in »PLC Designer« / Inserting the CANbus
devices :
• The basic node, that is the uppermost entry in a CANbus configuration tree, must
be the "CANbus" object. A CANbus can only be inserted below an appropriate
programmable device. So select this device in the tree and choose "CANbus" in the
'Add Device' dialog:
Abb. 479 Add CANbus object
• In the CANbus node check or adapt the baud rate for the data transfer on the bus
and the number of the CAN network to be connected via the CANbus interface.
• Below a CANbus entry the obligate device object "CANopen Manager" must be
inserted. This can be seen as the "master" of the CANbus. It currently supports the
configuration of the CANbus by internal functions and so no configuration input by
the user is needed. The CANopen Manager simplifies the setup of the connections
within the network, especially by helping to simplify the PDO-Linking between the
particular modules
