CECX-B-CO
CANOpen bus link module:
ï‚· for up to 12 add-on modules.
The CECX-B-CO is a CANOpen bus link module, and may be connected as slave module to each CAN
master module.
Set the values of the CAN parameters as desired (baudrate according to length of data line, other
parameters adequate to the settings at the CAN modules).
When configuring the CAN master, consider that the parameter „Support DSP301,V4.01 and
DSP306“ is selected. If this option is set, then the CAN module selection is available.
