6. EtherCAT Settings

This section describes the procedure for connecting the PLC to the Digital Sensor
Communication Unit via EtherCAT.

6.1. EtherCAT Communications Settings

The settings required for communications between the PLC (Position Control Unit) and the
Digital Sensor Communication Unit are given below.
6.1.1. EtherCAT Communications Setting Contents
The settings required for EtherCAT communications are given below.
Unit number
Node address
Additional Information
The node addresses 17 onwards are set for CJ1W-NC[]82 when EtherCAT-compatible
devices other than G5-series Servo Drives are connected.

6.2. DS-Bus Communication Settings

The setting required for communications between the Digital Sensor Communication Unit and
the Distributed Sensor Unit is given below.
6.2.1. DS-Bus Communication Setting Contents
The settings required for communications through the Inter-Unit DS-Bus network are given
below.
Unit address
Termination setting
*The Sensor unit numbers are automatically assigned after turning ON the power supply to the
Digital Sensor Communication Unit and to the Distributed Sensor Unit.
In this document, one Fiber Amplifier is connected to the Digital Sensor Communication Unit
and another one to the Distributed Sensor Unit. The Sensor unit number 1 is assigned to the
Fiber Amplifier that is connected to the Digital Sensor Communication Unit, and the Sensor
unit number 2 is assigned to the Fiber Amplifier connected to the Distributed Sensor Unit.
Additional Information
For details on the Inter-Unit DS-Bus network, refer to A-2 Using Distributed Sensor Units of
the EtherCAT Digital Sensor Communication Unit Operation Manual (Cat. No. E429).
