4.2.4.2 PROFIBUS with CANopen or EtherCAT
The PROFIBUS bus system can be combined with CANopen or EtherCAT.
This makes sense if not all field devices are available for the same bus system or a mo-
tion bus is required in parallel to the PROFIBUS.
The bus systems are synchronised in the control, the IPC (controller).
The following combinations are allowed:
PROFIBUS (as logic bus) and up to two CAN interfaces (as motion bus)
For the configuration and parameterisation of the bus systems the data in the
corresponding communication manuals apply:
• CANopen communication manual
• EtherCAT communication manual
• PROFIBUS communication manual
Note!
A mixed operation is only possible with Industrial PCs which have two extension
slots for communication cards.
• When the Command Station is used, a mixed operation is not possible!
