4.3 Connecting to CANopen Bus
4.3.1 Connecting to CANopen Port

Please wire CANopen connector according to its pin definitions

Plug the communication terminals into the CANopen connection port of RTU-CN01.
4.3.2 CANopen Network Topology
Both of the two ends of a CANopen network need be connected with the terminal resistors of 120Ω to
enhance the stability of CANopen communication. See the illustration of a basic CANopen network topology
below.

4.3.3 Connecting to CANopen Port

Delta standard cables, UC-DN01Z-01A thick cable, UC-DN01Z-02A thin cable and UC-CMC010-01A
thin cable are recommended for building a CANopen network. Please keep the communication cable
away from the power cable. For specifications of cables, see List of Accessories in Appendix A.

The terminal resistor of 120Ω should be connected between CAN_H and CAN_L of two respective ends
of the network. Users can purchase Delta terminal resistor, TAP-TR01.
