Physical structure
 The Industrial PC (IPC) is the PROFIBUS master. It can communicate with one or several
stations (slaves).
 The PROFIBUS has an internal line topology (without repeater) or a tree topology (with
repeater).
 The PROFIBUS network must be terminated at the first and last station.
 The bus terminating resistor is integrated in the bus connector and activated by a
switch.
4.2.4 Mixed operation
4.2.4.1 Combination of CANopen and EtherCAT
It is possible to combine both bus systems CANopen and EtherCAT in a control system.
This combination of CANopen and EtherCAT may be sensible if controllers with EtherCAT
are available but further peripheral devices have to be controlled which are only available
with CANopen. Both bus systems are synchronised via the control system, the IPC (control-
ler).

Note!
Mixed operation is only possible with Industrial PCs provided with two extensi-
on slots for communication cards.
• Thus, the "Command Station" is not suitable for mixed operation!
