XC-NET-CAN CANopen module
General
The module provides the ISO 11898 interface between the CPU
module and the CANopen bus.
module and the CANopen bus.
Task of the module
The module provides the master function for 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 line.

CANopen interface
The module can be connected to the CANopen bus via the isolated
ISO 11898 interface.

Power supply
The power supply module provides the 5 V supply to the modules
via the PC/104 bus.
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 line are switched on simultaneously or before the
controller. This prevents any errors occurring during the starting of
the CANopen line.
on the CANopen line are switched on simultaneously or before the
controller. This prevents any errors occurring during the starting of
the CANopen line.
Start/Stop behaviour
Setting the OMS to the STOP position will cause all the outputs of
the remote devices to be set to 0.
Setting the OMS to the STOP position will cause all the outputs of
the remote devices to be set to 0.
An interruption on the line will cause all inputs of the disconnected
devices (receive data) to be interpreted by the PLC as 0 signals and
the outputs set by the PLC in the output module to be reset.
Devices that are still connected with the PLC will continue to be
interrogated.

Configuring the 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 range for each module in the CPU by defining a module
address for each one:
