cANOPEN
The function of the bus system is the high-speed serial connection of decentral peripheral elements with the
central master (controller). Diagnostic data are transmitted in addition to the input / output data.
Many CANopen master (controllers) require a configuration program. This program requires an Electronic
Data Sheet (EDS) file containing bus-specific data.
Data of the cANopen (excerpt)
Available baud rates 20 / 50 / 100 / 125 / 250 / 500 / 800 / 1000 kBaud
Data volume without RIO expansion 2 input and 2 output bytes
Data volume with RIO 8645 expansion or interme-
diate module 2 input and 2 output bytes per expansion
Data volume with RIO 8640 4 input and  output bytes
Preparation for commissioning�
A precondition for successful commissioning is a correctly installed device.
Check all the plug connectors (voltage, bus) and the pneumatic connections.
Set the bus address.
NOTE!
Instructions for this can be found in the chapters Installation and Configuration and
Function of the Modules.
Starting� Procedure
If there are RIO and/or intermediate modules in the system, these must be supplied with voltage and hence
switched on before or at least at the same time as the CANopen field bus module (FBM).
After the start-up sequence, the CANopen FBM is in PRE-OPERATIONAL mode.
How the CANopen master switches the field bus module to the normal OPERATIONAL status is explained in
the next chapter
Commissioning using an Example.
