ControlLogix DH-485 Network Communication Overview
On the DH-485 network, the ControlLogix 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 two controllers for each 1761-NET-AIC converter, but
you need a separate cable for each controller. Connect the serial port
of the 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.
Cable Selection
IMPORTANT
A DH-485 network consists of multiple cable segments. Limit
the total length of all the segments to 1219 m (4000 ft).
