The 1756-RIO Module-Getting Started
Introduction
This document is a user’s guide for the 1756-RIO module. The module lets
Rockwell Automation ControlLogix controllers communicate with remote I/
O over the backplane or over a remote network. This chapter describes the
ControlLogix 1756-RIO module and how it links a ControlLogix controller to
the Universal Remote I/O network.
This chapter also describes the module’s physical features, software
requirements, software and add-on profile installation instructions, and
RSLogix 5000 project setup.
The 1756-RIO module:
supports native RIO 16-bit words for data, control, and status bits.
acts as a scanner on a Remote I/O network.
acts as an adapter that exchanges data on a Remote I/O network.
supports discrete data and block transfer data in either mode.
supports up to 10 produced/consumed data connections (along the
backplane between the ControlLogix controller and the 1756-RIO
module) with 248 words of integer input and 248 words of integer
output for each connection.
uses produced/consumed connections using a 1756-RIO add-on profile
in RSLogix 5000 programming software.
supports requested packet intervals (RPIs) from 2…750 ms. All
connections use one set RPI.
maps all discrete and block transfer data into produced/consumed
connections.
monitors existing I/O in adapter mode (Monitor mode). It can report
all existing inputs and outputs, discrete and block transfer module data
to the ControlLogix controller.
