On the DH-485 network, the controller can send and receive messages to and from other
controllers on the network. The DH-485 connection does support remote programming and
monitoring via RSLogix 5000 software. However, excessive traffic over a DH-485
connection can adversely affect overall performance and can lead to timeouts and loss in
RSLogix 5000 configuration performance.
Important: Only use Logix5000 controllers on DH-485 networks when you want to add
controllers to an existing DH-485 network. For new applications with Logix5000
controllers, networks in the NetLinx open architecture are the recommended networks.
You need a 1761-NET-AIC+ converter for each 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).
