XC-NET-CAN CANopen module

Assign the input/output address range (%IB/%QB) to the module

in the PLC configuration in XSoft:

The modules are integrated in turn into the PLC configuration:

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. Assign the range starting

with address CC000 to the second module and D4000 to the third.

Bus terminating resistors

120 O bus terminating resistors must be provided at the ends of

the networks. Standard plugs are available that allow the bus

terminal resistor to be enabled or disabled via a slide switch on the

plug, e.g. the SUBCON-PLUS-CAN plug from Phoenix Contact,

Order No. 2744694

Only use CANopen-approved cable with the following features:

• Ripple resistance 108 to 132 O

• Capacitance < 50 pf/m
