Network Communication Chapter 2

On the DH-485 network, the CompactLogix controller can send and receive

messages to and from other controllers.

For the controller to operate on a DH-485 network, you need a

1761-NET-AIC interface converter for each controller you want to put on the

DH-485 network.

You can have one packaged controller for each 1761-NET-AIC converter.

Configuration for a DH-485 Network

To establish DH-485 communication, complete this procedure.

1. Connect the serial port of the controller to either port 1 or port 2 of the

1761-NET-AIC converter.

2. Use the RS-485 port to connect the converter to the DH-485 network.

The cable you use to connect the controller depends on the port you use

on the 1761-NET-AIC converter.

3. In RSLogix 5000, open the Controller Properties dialog box by

right-clicking the packaged controller and choosing Properties.

IMPORTANT

A DH-485 network consists of multiple cable segments. Limit

the total length of all the segments to 1219 m (4000 ft).
