Rockwell Automation 5730 DriveLogix5730 Controller for PowerFlex 700S Drives with Phase II Control - Manual (Page 180)

9-2 Communicating with Devices on a DH485 Link
Configuring Your System for
a DH-485 Link For the DriveLogix5730 controller to operate on a DH-485 network, you
need:
a 1761-NET-AIC interface converter for each DriveLogix5730 controller
you want to put on the DH-485 network.
You can have two controllers per one 1761-NET-AIC converter, but you
need a different cable for each controller. Connect one controller to port 1
(9-pin connector) and one controller to port 2 (mini-DIN connector).
RSLogix 5000 programming software to configure the serial port of the
controller for DH-485 communications.
When attempting to go online or upload/download a program using the
Communications/Who Active window in RSLogix 5000 software, disable
the Autobrowse feature to minimize traffic from RSLogix 5000 software on
the DH-485 network.
Step 1: Configure the Hardware
The RS-232 port is built-in to the front of the DriveLogix5730 controller.
The 1769-L31 controller has two serial ports. Connect the serial port to an
RS-232-to-RS-485 interface converter. One possible converter is the
1761-NET-AIC interface converter.
Connect the serial port of the DriveLogix5730 controller to either port 1 or
port 2 of the 1761-NET-AIC converter. Use the RS-485 port to connect the
converter to the DH-485 network.
