Hardware and Engineering

12/01 AWB2700-1428GB

X Assign the memory range beginning with start address CE000

to the first module (CANopen or PROFIBUS-DP) to be

configured.

The input/output devices assigned to this module are connected to

the module bus system via address CE000.

X Assign the range starting with address CC000 to the second

module and D4000 to the third.

Bus terminating resistors

Bus terminating resistors must be provided at both ends of the

cable.

XC-NET-CAN CANopen module

General

The module provides the ISO 11898 interface between the CPU

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.

The CANopen modules can be fitted between the power supply

module and the CPU module. Up to three modules (PROFIBUS-DP

or CANopen) can be fitted.

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 CiA DS 102

(CAN Physical Layer for Industrial Applications) standard.

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 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.

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:

X Set the address for each module using the jumpers in the

jumper field from range 13 to 17 (a following figures).

Figure 20: Example configuration with three modules and the

assigned addresses

When using the ZB4-209-DS2 PROFIBUS plug, the bus

terminating resistor can be enabled or disabled via the

slide switch on the plug.
