Commissioning the CANopen Logic bus

Setting of CAN parameters and CAN mapping

DMS 4.2 EN 07/2011 TD17

Cross communication between the slaves
When the CAN bus is used for control, a cross communication between the slaves is

possible.
For this purpose, you must configure the CAN communication and the PDO mapping in the

»Engineer« or in the »Global Drive Control« and write it into the controller.
Since the mapping for the cross communication between the slaves is not available in the

control configuration, you must set the "Not initialise" option in the »PLC Designer« in the

CAN parameters tab:

Thus, the CAN and mapping settings in the slave drives will not be overwritten by the

control when the PLC program starts.

Note!

In addition to the cross communication between the slaves, the communication

to the master in the »Engineer« or in the »Global Drive Control« must be

configured as well. Also this part of the PDO mapping will not be written

anymore when the "Not initialise" option is active.
