Preface

Introduction

This manual describes how to configure and troubleshoot your Logix Remote I/O (RIO) Communication Module.
The 1756-RIO module:
• runs in a ControlLogix environment.
• allows upgrade from PLC-5, PLC-3, or SLC systems to a ControlLogix system with a minimum of downtime and startup time.
• uses integer data.
• does not require MSG instructions. All data is scheduled.
• offloads block transfer execution to reduce processing burden on the processor.
This publication explains how and why you would use a 1756-RIO module. The module is used in two modes, scanner and adapter mode.
In scanner mode, the 1756-RIO module enables communication and data transfer between a ControlLogix controller and devices on a Remote I/O network. The module continuously scans adapters on the remote network. The module transfers discrete and block transfer data.
In adapter mode, the module performs two functions simultaneously. First, it emulates one or more racks of I/O to a scanner, exchanging data with that scanner. Second, it monitors other remote I/O racks on the same Remote I/O network.
It can be used to upgrade an existing PLC-5, PLC-3, or SLC system to a ControlLogix system.
The advantages of using the 1756-RIO module to upgrade your system include:
• allowing the user to leave the existing Remote I/O network in place, alleviating the time and/or expense of replacing the I/O and field wiring, or the process of testing out field wiring.
• allowing the new application to be tested before you switch over, so that it works just like the old one.
• allowing you to switch back to the old application in minutes, should you run into problems.

1756-RIO Module Requirements

The 1756-RIO Modes

The requirements for the module to operate include the installation of:
RSLogix 5000 programming software, version 17 or later, and the
associated controller firmware.
RSLinx software, version 2.54 or later, with an activation. Use RSLinx
Gateway or RSLinx Professional software. Do not use RSLinx Lite software.
the 1756-RIO module add-on profile from the CD provided with the
module.
the 1756-RIO module installed in a 1756-ControlLogix chassis.
The 1756-RIO module can be used in various capacities depending on the user’s needs. First, decide which mode you want the 1756-RIO module to use.
In most cases, the module is used in scanner mode to scan and control remote I/O data on a network.
In adapter mode, the 1756-RIO module can perform two functions simultaneously. First, the module can emulate one or more racks of I/O to a scanner, exchanging data with that scanner (for example, a PLC-5, PLC-3, or SLC). It can exchange data with the scanner as discrete data, or via block transfers.
Second, the 1756-RIO module can act as a ‘shadow,’ referred to as Monitor mode, to monitor racks on a remote network. The module listens to the remote I/O and provides all inputs and outputs from the existing scanner to the ControlLogix controller. Users can then run their converted logic against those inputs, generate temporary outputs, and compare the existing outputs with outputs generated by the new logic.

Installing the add-on profile also installs the software configuration tool. The add-on profile and the configuration tool (56RioCfg) are on the CD that ships with your module.
Once loaded onto your computer, the configuration tool is accessible within the RSLogix 5000 add-on profile. The configuration tool contains two separate programs; one for scanner mode, 56RioCfgScan; and one for adapter mode, 56RioCfgAdpt. The program that launches depends on which mode you select.
.
The 1756-RIO module requires RSLogix 5000 programming software, version 17, or later. The add-on profile does not work with previous versions of RSLogix 5000 programming software.
With the configuration tool, you can:
• change modes.
• set the baud rate.
• autoconfigure racks from an attached Remote I/O network.
• manually add and configure racks.
• add and configure block transfer modules.
• map I/O data to the ControlLogix controller produced/consumed
connections.
• save and load configuration files.
• download and upload configurations.
• archive projects.
• monitor diagnostics, rack status, discrete data, and block transfers.

Module Definition Dialog Box
Item Description
Series Module series letter. Revision Firmware revision number. Electronic Keying Exact Match: requires all keying attributes of the physical module and the module created in the software to
match precisely to establish communication. Compatible Module: the module determines whether to accept or reject communication. Compatible Keying
allows the physical module to accept the key of the module configured in the software, provided that the configured module is one the physical module is capable of emulating. This is the default setting.
Disabled Keying: indicates the keying attributes are not considered when attempting to communicate with a module. Be extremely cautious when using this option; if used incorrectly, this option can lead to personal injury or death, property damage, or economic loss.
Mode - Scanner or Adapter
The module ships in scanner mode. (The 4-character display on the front of the module also indicates which mode is set.) If you want to change the mode setting, you must first select the desired mode in the add-on profile on the Module Definition dialog box from the pull-down menu, so that the correct configuration tool starts. Then, on the Remote I/O tab, you must click on the Configure Remote I/O devices button (the configuration tool), and select the Tools menu>Set 1756-RIO Module/Scanner mode to download the correct firmware.
Be aware that changing the module mode downloads firmware specific to the mode chosen. This mode setting must match between the RSLogix 5000 programming software project and the configuration tool, but keep in mind that the correct firmware must also be downloaded.
Input Tags - Output Tags
Up to 10 input and output tags can be selected. Each tag is 248 words. The number of input/output tags entered in the add-on profile’s Module Properties has to be equal or greater than the number of tags in the configuration tool.
The number of tags in the configuration tool are determined by the mappings you create. The more tags you have, the more backplane traffic is generated. It’s best to keep the number of tags low, which is what the automatic mapping command does, by mapping the data and packing it into the lowest number of tags.
For example, a single rack with discrete data that has the inputs/outputs mapped to block 9 requires the input/ output tags to be 10. So, in the Module Properties>General tab>Module Definition>Change button, select 10 for the number of input and output tags.

IMPORTANT

Enter the RPI

To set the RPI, follow these steps.
1. On the controller organizer, double-click on the RIO module.
2. On the Module Properties dialog box, from the Connection tab, set the
RPI for the module.
If you are using the 1756-RIO module in a remote rack, for example, a rack connected to the controlling ControlLogix controller over ControlNet or Ethernet/IP, it may be necessary to increase the RPI, as the intermediate network may not have sufficient bandwidth to support faster updates (small RPIs). The likelihood of having bandwidth issues is increased as you increase the number of 248-word input and output tags.
Publication 1756-UM534B-EN-P - November 2010 27
Chapter 1 The 1756-RIO Module-Getting Started
Remote I/O Update Time
The remote update time is the time it takes the Remote I/O scanner to scan all of the adapters in its I/O scan list.
Baud Rate Scan Rate
230.4 K 3 ms
115.2 K 5 ms
57.6 K 8 ms
The scan rate is the approximate time it takes to scan a 16-slot logical chassis without block transfers. The number and sizes of block transfers can significantly affect this time.
So, for example, if you have eight adapters on your network and your baud rate is 230.4 K, your approximate remote I/O update time would be 8 (# of adapters) * 3 ms (scan rate), or, 24 ms.
RPI
The Requested Packet Interval (RPI) specifies the rate at which the 1756-RIO module and the ControlLogix controller exchange data to and from each other. The allowable RPI’s range is from 2…750 ms, with a default of 20 ms. When the specified time frame elapses, the 1756-RIO module and the ControlLogix controller produce data for each other. All 1756-RIO input and output tags update with the same RPI.
Select an RPI for your application. For most applications, a good rule of thumb would be to set the RPI equal to one half of the remote I/O scan time.
28 Publication 1756-UM534B-EN-P - November 2010
The 1756-RIO Module-Getting Started Chapter 1
Throughput
When using the 1756-RIO module, your system throughput is based on the following key factors:
Number and sizes of adaptersNumber and sizes of block transfer modulesOverall remote I/O update timeRPIAny network cards involvedController scan timeThe asynchronous nature of the RPI and the remote I/O scan
Since the RIO scan is asynchronous to the RPI, the worst case, or maximum update time to get information from the 1756-RIO into the controller is the RPI plus two times the remote I/O update rate.
You can use the diagnostic functions of the 1756-RIO configuration tool’s utilities to measure the average, minimum, and maximum update times on the Remote I/O network.
