CANopen module XC-NET-CAN
General
This module provides the interface as per ISO 11898 between the
CPU module and the CANopen bus.
Task of the module
The module provides the master function for the CANopen bus. It
organises and operates the data exchange between the user
program and the connected slaves. Up to 126 nodes can be
connected to a segment.
The CANopen modules can be plugged in between the power
supply module and the CPU module. Up to three modules
(PROFIBUS-DP or CANopen) can be fitted.
Project engineering
CANopen interface
The module can be connected to the CANopen bus via the isolated
ISO 11898 interface.
Pin assignment
Connector assignment in accordance with the standard
CiA DS 102 (CAN Physical Layer for Industrial Applications).
Power supply
The power supply module provides the 5 V supply to the modules
via the PC/104 bus.
Set the system power supply so that the connected remote stations
on the CANopen segment are switched on simultaneously or
before the controller. This prevents any errors occurring during the
starting of the CANopen segment.
Start/Stop behaviour
Setting the OMS to the STOP position will cause all the outputs of
the remote devices to be set to 0.
An interruption in the segment causes the inputs (receive data) of
the disconnected devices to be interpreted as 0 signals by the PLC,
and the outputs that were set by the PLC in the output module will
be reset. Devices that are still connected to the PLC will continue
to be interrogated.
Configure module address
Up to three XC-NET-DP-M (PROFIBUS-DP) or XC-NET-CAN
(CANopen) modules can be used in any combination. Reserve a
memory area for each module in the CPU by defining a module
address for each one:
X
Set the address for each module with the aid of jumpers in the
jumpers block in the jumper block range from 13 to 17:
Assign the input/output address range (%IB/%QB) to the module
in the PLC configuration in XSoft:
