Introduction 3

In the typical configuration illustration, a ControlNet port on the controller

interfaces the processor to the ControlNet link. In each of the two chassis

remote from the controller, a 1771-ACN15 I/O Adapter Module provides

I/O modules in those chassis with an interface to the ControlNet link. In this

configuration, the PLC-5 controller monitors/controls the I/O in its local

I/O chassis as well as the I/O in the remote locations.

Plug a 1771 power supply module into an I/O module slot, or connect a

standalone 1771 power supply into the left end of each chassis.

Depending on the communication ports available on your particular PLC

control system, you can select operator interfaces that are compatible with

those particular ports.
