About the Module
Chapter Objectives This chapter describes the ControlNet adapter (Catalog Number
1734-ACNR) and contains the following main sections.
• adapter description and features
• hardware components that include diagnostic indicators, a
network access port (NAP), and network address switch
assemblies
This manual addresses the 1734-ACNR, Series A adapter that is
compatible with ControlLogix, FlexLogix, and SoftLogix (5800). It is
not compatible with PLC-5 and SLC processors. Use a Series B adapter
(not released when we wrote this manual) with PLC-5 and SLC
processors.
The 1734-ACNR adapter manages data transfers between controllers
on the ControlNet network and POINT I/O modules plugged into the
POINTBus backplane.
The ControlNet network is a communication architecture that enables
the exchange of messages between ControlNet products compliant
with the ControlNet International specification.
The 1734-ACNR adapter features include a variety of control system
solutions, a
local communication network access through the network
access port (NAP), and redundant media.
