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.

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 adapters  Number and sizes of block transfer modules  Overall remote I/O update time  RPI  Any network cards involved  Controller scan time  The 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.

Configure Scanner Mode

Chapter

Introduction

Once the 56RioCfg configuration tool launches, you can configure a Remote I/O network using the RIO module as a scanner, or an adapter. This chapter describes how to configure the module for use in scanner mode.

In scanner mode, the ControlLogix controller writes remote I/O outputs and reads remote I/O inputs. The 1756-RIO module enables communication between the controller and devices on a Remote I/O network. The scanner continuously scans the adapters on the Remote I/O network.

Two types of data are transferred over the Remote I/O network - discrete and block transfer data. Discrete data transfers consist of the scanner sending output data and communication commands to the adapter, which instruct the adapter about how to control its output. The adapter responds by sending input data to the scanner.

The remote I/O block transfer module is a data transfer mechanism that lets you control the transfer of up to 64 words of data to or from a remote device. The 1756-RIO module allows the user to offload block transfer execution from the controller. The data appears in the data table of the ControlLogix controller without having to execute the logic in the controller to perform the block transfer. A Block Transfer Read (BTR) receives data from a remote device. A Block Transfer Write (BTW) sends data to a remote device.

In this chapter, you use the configuration tool to configure the module in scanner mode to prepare it for use on the Remote I/O network. You will:

• configure the racks automatically, or manually.

• add and configure block transfer modules.

• map the remote I/O modules to the ControlLogix controller produced/

consumed data.

Configure Scanner Mode Chapter 2

TIP

Set the Baud Rate

After setting the operating mode for the 1756-RIO module, you must set the baud rate.

1. On the 56RioCfgScan dialog box, right-click on the controller on the I/ O tree and from the pull-down menu, select 1756-RIO Properties.

Autoconfigure Racks

You can autoconfigure racks attached to the network, or add additional racks manually. The Autoconfigure command scans the Remote I/O network to determine which racks are present.

The module automatically detects the network baud rate and configures the racks on the attached Remote I/O network.

The 56RioCfgScan tool sends messages to all possible racks, detects all possible baud rates, and from the replies, determines which racks are on the network.

IMPORTANT

The icons on the 56RioCfgScan tool show the partial rack sizes and locations. Racks are shown with starting and ending I/O groups. For example, the following tree shows rack 0 consisting of 4 quarter racks.

Block transfer modules must be added and configured manually.

The controller with the connection to the 1756-RIO module must be in program mode when you perform an autoconfiguration. The following error message displays if the controller is not in program mode.

When the module is in scanner mode, the 1756-RIO module performs the following actions during autoconfigure. The module:

• detects the network baud rate by sending messages at each baud rate, looking for responses.

• then sends messages to all possible racks on the network.

• builds a network configuration from the observed network responses.

• displays the network configuration.

TIP

Main Menu

Toolbar

To perform an autoconfigure in scanner mode, follow these steps.

1. On the main menu, from the Configure menu, select Autoconfigure, or click the Autoconfigure button on the toolbar.

Any configuration previously stored in the 1756-RIO module is overwritten by the data from the autoconfiguration. You are given the option to save the previous configuration before it proceeds with the autoconfiguration.

Autoconfiguration detects just the rack structure, it cannot locate block transfer modules. You have to manually add block transfer modules to the rack.

There is no specific ’auto’ baud rate when the module is in scanner mode. When using autoconfigure, the 1756-RIO module tries all three baud rates and sets the baud rate based on the responses to the messages it sends. You need to make sure that all devices on the network are set at the same baud rate.

After performing an Autoconfigure, what displays by the 56RioCfgScan tool matches what is in the 1756-RIO module. No download is necessary. The Autoconfigure also automatically maps the discrete rack data to tags in the ControlLogix processor.

Configure Block Transfer Modules

46 Publication 1756-UM534B-EN-P - November 2010

All block transfer modules represent some type of analog data. Block transfer modules transfer a block (64 words maximum) of analog-type data at a rate configured by the user. The 1756-RIO module lets the user offload block transfer execution from the controller to the 1756-RIO module.

If a slot is occupied by a discrete I/O module, or is empty, select ‘Discrete’, which is the default. If a specific block transfer module occupies the slot, select the part number of that block transfer module.

Not all block transfer modules are supported directly by the 1756-RIO module. If the module you are using does not appear in the list, set the module type to BT-MODULE and set the lengths to the appropriate values. In some cases, there are multiple templates for a given block transfer module to show that the module can be used in significantly different ways.

See Appendix D

for additional information on block transfer templates.

Configure Scanner Mode Chapter 2

IMPORTANT

TIP

All block transfer data is mapped into one of the possible 10 produced/ consumed connections on the controller. Each produced/consumed connection allows 248 16-bit words, in and out. There are two words of overhead for each block transfer for control/status. The 1756-RIO module can execute as many block transfers as the user configures up to the limits of available memory mapped to the ControlLogix controller.

Block transfers do not need MSG instructions to execute.

In scanner mode, block transfer modules can be configured manually, also.

To configure a block transfer module, follow these steps.

1. On the 56RioCfgScan dialog box, expand the I/O tree to choose the

location where you want to add the module.

2. On the I/O tree, right-click the slot where you want to add the module and select Module Properties.

Chapter 2 Configure Scanner Mode

Type Description

Automatic 1756-RIO module controls block transfer update.

Automatic block transfers perform a single configuration block transfer write every time the controller transitions from Program to Run mode and then perform timed data block transfer read and write updates using the BTR and BTW data lengths and times from the configuration tool. The length values and update times for automatic block transfers all come from the configuration tool.

Automatic block transfers begin as soon as the controller is in run mode; they do not have to be triggered.

Errors in block transfer execution are indicated by non-zero values returned to the ControlLogix controller.

In automatic mode, the module configuration data values come from the configuration tool as default values, or from user parameters. The size of the configuration block transfer write is the data BTW length, BtwLen, plus the Config BTW Length, CfgLen, from the template. The data block transfer write length is BtwLen from the template and this is the length mapped to ControlLogix output data.

The size of the data block transfer read is set by the configuration tool.

Semi-automatic 1756-RIO module controls block transfer update.

Semi-automatic block transfers perform a single configuration block transfer write every time the controller transitions from Program to Run mode and then perform timed data block transfer read and write updates using the BTR and BTW data lengths and times from the configuration tool. The length values and update times for semi-automatic block transfers all come from the configuration tool.

Semi-automatic block transfers begin as soon as the controller is in run mode; they do not have to be triggered.

Any errors in BT execution are indicated by non-zero values in the ControlLogix controller.

In Semi-automatic mode, the module configuration data values come from ControlLogix output data. The size of the configuration block transfer write is the data BTW length, BtwLen, plus the Config BTW Length, CfgLen, from the template, and this is the length mapped to ControlLogix output data. The data block transfer write length is BtwLen from the template.

The size of the data block transfer read is set by the configuration tool.

Manual The ControlLogix controller controls block transfer update.

I/O module configuration gathers data from the ControlLogix controller.

To execute block transfers in manual mode:

 enter the BTR and/or BTW length and BTW data in the control block for the module.  set the BTR.EN and/or BTW.EN bits (BTR.CONT/BTW.CONT) for continuous execution.  check the BTR.DN/BTW.DN bits that indicate BT execution is complete (BTR data is available at that time).  check the BTR.ERR/BTW.ERR bits. If set, read the error code to determine the cause of the problem.

Inhibit Automatic Block Transfers

To inhibit a running automatic, or semi-automatic block transfer, set bit 9 to offset 0 of the mapped output data for the module.

8. On the I/O Module Properties dialog box, select the block transfer read-and-write-update rates, from 0…16,383 ms.

A rate of 0 means the 1756-RIO module updates the block transfer as fast as the network and the block transfer module allows.

Configure Scanner Mode Chapter 2

IMPORTANT

Map I/O Data

You must map the I/O data to locations in the ControlLogix controller input and output data before you can scan the Remote I/O network.

It is essential that the control program on the host controller matches the addresses in the mapping configuration on the 1756-RIO module, otherwise the control program may inadvertently write to the incorrect I/O locations. If you change the data mappings on the 1756-RIO module, make sure that the control program uses the correct addresses.

Mapping connects locations in the ControlLogix input and output tags to locations on the Remote I/O network (discrete data on racks and block transfer reads and writes.)

Connections (produced/consumed) occur between the 1756-RIO module and the ControlLogix controller. They are point-to-point links between two end points.

Produced/consumed tag data is the information that gets passed back and forth over the line between the two end points.

There are up to 10 blocks of produced/consumed tag data. Discrete and block transfer tag data gets ‘packed’ into the ControlLogix produced/consumed data. When discrete and block transfer tag data are mapped, or when the configuration tool ‘auto maps’ the data for you, you are selecting which of those blocks the tag data is mapped to, and the offset in the block where the tag data is found.

See Scanner Mode I/O Map

When mapping is complete, you must export the aliases to the 1756-RIO module and import the configuration to the RSLogix 5000 project.

See Aliases aliases.

Mapped Data

Unassigned, or unmapped, data (I/O addresses) are shown as xxx in the I/O tree.

If you change mappings, make sure you clear the output table in the ControlLogix controller to prevent inadvertently writing to an incorrect I/O location. If you leave a value behind in the output table, it now points to something else on the Remote I/O network. To clear the output table, set the outputs to 0. You must also re-import the aliases.

Chapter

Introduction

This chapter explains how and why to use the 1756-RIO module in adapter mode. 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 controller). On Active racks, the module writes remote I/O inputs and reads remote I/O outputs.

Second, it can monitor other remote I/O racks. On Monitored racks, the 1756-RIO module can monitor existing I/O, also known as ‘Monitor mode,’ and can be used to upgrade a PLC-5, PLC-3, or SLC system to a ControlLogix system. Monitor mode provides existing discrete inputs and outputs, and Block Transfer reads and writes to the ControlLogix controller.

See Scan Mode and Monitor Mode using Monitor mode.

The 1756-RIO module communicates with the ControlLogix controller using up to 10 input connections and 10 output connections via produced/ consumed data. Remote I/O data maps into the connections by the configuration tool.

on page 99 for a complete description of

In this chapter, you use the configuration tool to configure the module in adapter mode to prepare it for use on the Remote I/O network. You will:

• configure the racks automatically or manually.

• add and configure block transfer modules.

• map the remote I/O modules to the ControlLogix controller produced/

consumed data.

Configuring the 1756-RIO module as an adapter enables the RIO module to emulate a 1771-ASB module. This allows a path for peer-to-peer data to be exchanged between the scanner controller and the ControlLogix owner of the RIO module over the Remote I/O network. The adapter mode functionality does not allow the scanner controller to directly control any 1756-I/O in the chassis with the RIO module.

Configure Adapter

The following list summarizes the steps to configure the 1756-RIO module in adapter mode.

Summary

62 Publication 1756-UM534B-EN-P - November 2010

1. Set the baud rate.

2. Autoconfigure online racks on the network. (Make sure the controller is

set to Program Mode.)

3. Set the communication path.

4. Manually add any additional racks that are not online.

5. Manually add and configure block transfer modules.

6. Map/Automap the data.

Configure Adapter Mode Chapter 3

The default baud rate is Auto (automatic baud rate detection).

TIP

Set the Baud Rate

To set the baud rate in adapter mode, follow these steps.

1. On the 56RioCfgAdpt dialog box, right-click on the controller on the I/ O tree and from the pull-down menu, select 1756-RIO Properties.

The 1756-RIO Properties dialog box displays.

2. On the 1756-RIO Module Properties dialog box, select the baud rate.

Value Baud Rate, Kbps

57 k 57.6 115 k 115.2 230 k 230.4 Auto - adapter mode default Auto

If you perform an autoconfiguration, the 1756-RIO module automatically detects the baud rate by monitoring an attached Remote I/O network.

If you are only using Active racks, set the baud rate to match the Remote I/O network. Don’t set it to Auto.

3. You can also enter an LED Banner name. This is a unique name you assign to identify the module. This is useful when you have multiple RIO modules on your network. The LED Banner displays on the 4character display on the 1756-RIO module. It can be from 0…15 characters long.

4. Click OK.

Chapter 3 Configure Adapter Mode

IMPORTANT

ATTENTION

Autoconfigure Racks

When the module is in adapter mode, autoconfigure builds a configuration based on what it has heard on a running network. This process differs from scanner mode, because the 1756-RIO module does not scan these racks, only monitors the information to and from these racks.

The controller with the connection to the 1756-RIO module must be in program mode when you perform an autoconfiguration.

The module automatically detects the network baud rate and configures the racks on an attached Remote I/O network. Autoconfiguration detects the rack structure and causes the 1756-RIO module to monitor the data to and from these racks. Active and monitored racks are displayed.

See Active Versus Monitored Racks on the Network

on page 67 for detailed

information about active and monitored racks.

Autoconfigure in adapter mode performs the following actions:

• Detects the network baud rate

• Monitors messages to and from racks on the network

• Builds a network configuration from the observed network traffic

• Displays the network configuration

To autoconfigure in adapter mode, you must:

• clear the old configuration.

• download a new, empty configuration.

• set the baud rate to ‘auto’, or to the baud rate that matches the existing

network.

• put the scanner in Run mode until all block transfers execute.

• put the scanner back in Program mode.

• perform the autoconfiguration.

Please note, any configuration previously stored in the 1756RIO module is overwritten by the data from the autoconfiguration. You are given the option to save the previous configuration before it proceeds with the autoconfiguration.

Active Versus Monitored Racks on the Network

You must distinguish between active and monitored racks, and must manually enter active racks into the 1756-RIO module’s configuration, and manually add any desired block transfers.

On monitored racks, the 1756-RIO module picks up the block transfers automatically, but must have the specific module type set. This insures that the aliases you create for import into the RSLogix 5000 project have names that better describe the data content. Otherwise, the generic module type, BTMODULE, is set.

If you want active racks, add them manually now, then download the modified configuration to the 1756-RIO module.

In the configuration tree, each rack line precedes an icon representing rack information. The icons represent type and size. The size, color, and position of the colored block indicates the location, size, and type of partial rack, and whether the rack is active or monitored.

Active Versus Monitored Racks

Type Description

Active The 1756-RIO module emulates one or more remote I/O racks. The ControlLogix controller sends the rack-

produced data, which is then sent as remote I/O input data to the scanner on the Remote I/O network. The remote I/O scanner sends output data for those emulated racks to the 1756-RIO module in adapter mode. The RIO module then sends that data to the ControlLogix controller as consumed input data.

Use ‘Active’ if you want to exchange data between a ControlLogix controller and a scanner on remote I/O. You can also configure one or more slots in the Active rack as block transfer modules to exchange larger amounts of data with the remote I/O scanner. Active racks are one or more racks that the 1756-RIO module is emulating to share information between the existing scanner and the ControlLogix controller.

Any rack in the configuration tree that contains at least one portion of an Active rack displays with a lightning bolt and a red indication on the active portion of the rack. The text ‘Actlnp:Ox.Data[xxx]’ also displays, indicating that this data originated in the ControlLogix controller as output data that appears as input data to the remote I/ O scanner.

Monitor The 1756-RIO module monitors remote I/O inputs on an existing Remote I/O network, and passes data as

produced/consumed data to the ControlLogix controller. This is also known as ‘Monitor mode’. Use ‘Monitor mode’ if you have a supervisory ControlLogix system that needs to collect data from an existing control system with remote I/O.

Monitored racks are racks that physically exist on the Remote I/O network and are to be monitored by the 1756RIO module. Any portion of a rack in the configuration tree that is configured as ‘Monitor’ displays with a blue indication on the rack.

Lightning bolt denotes an active partial rack in the rack.

Rack 00 contains four monitored, quarter racks, so no ‘lightning bolt’.

The Add/Resize Rack dialog box displays.

2. On the Add/Resize Rack dialog box, choose the Rack number (in octal), the Start Group, the End Group, and Rack Mode (Monitor or Active).

Type Description

Active Emulates one or more remote I/O racks. The ControlLogix controller sends the rack produced/consumed data as

input data, which is then sent as remote I/O input data to the scanner on the Remote I/O network. The remote I/ O scanner sends output data for those emulated racks to the 1756-RIO module in adapter mode. The RIO module then sends that data to the ControlLogix controller as produced/consumed input data.

Use active if you want to exchange data between a ControlLogix controller and a scanner on remote I/O.

Monitor Monitors remote I/O inputs and outputs on monitored, remote I/O racks, and passes data as produced/consumed

input data to the ControlLogix controller. This is also known as ‘Monitor mode’. Use Monitor mode if you have a supervisory ControlLogix system that needs to collect data from older control systems with remote I/O.

Link Module Configuration with RSLogix 5000 Project

Introduction

Now that the configuration, mode selection, and network preparation in the configuration tool are complete, the next steps include downloading the configuration to the 1756-RIO module and exporting aliases to the RSLogix 5000 project. This completes the preparation of the 1756-RIO module for operation on a Remote I/O network.

In this chapter, you will:

• create aliases and export them to the RSLogix 5000 project.

• convert an older system to a ControlLogix system.

• download configurations to the module.

• upload configurations to the project.

• save configurations to disk.

• archive configuration templates.

EXAMPLE

IMPORTANT

Aliases

Aliases are used to access data in the ControlLogix system. They define the names and descriptions exported from the configuration program and imported into the RSLogix 5000 control program and should be used for adapter and scanner modes.

Aliases are symbolic names that point to I/O data. The configuration tool creates these aliases for discrete and block transfer data based on the I/O mappings. It is important that you develop the control program in the RSLogix 5000 project with reference to aliases as opposed to absolute addresses. Then, if the mappings change, the ControlLogix controller still operates; you just create aliases for the new mappings by exporting them from the configuration tool and re-importing them into the control program, which then points to the new data.

For example, let’s say you’re mapped rack 7 inputs to block 0, offset 8, so the data for rack 7, I/O group 0, is at input address I0:[10]. Now you add a rack 6 and remap everything so that now the rack 7 input data maps to block 0, offset 20.

The data for rack 0, I/O group 0, now moves to I0:[22]. If you had used absolute addresses in your control program, you

would have to re-address every instruction in the program. By using aliases, you can use the Export Aliases command from the configuration tool and import them into the RSLogix 5000 project, which automatically points to the new data.

You must export the new aliases from the configuration tool and import them into the RSLogix 5000 project before you run the program; otherwise, you could read wrong inputs and/or write wrong outputs.

Also, it’s important to note that export options in the configuration tool differ depending on whether you have your 1756-RIO module set for scanner or adapter mode.

In this section, you will cover:

• exporting aliases in scanner mode.

• exporting aliases in adapter mode.

• using the Export Aliases command in the configuration tool to upgrade

an existing system to a ControlLogix system.

To export aliases in adapter mode, follow these steps.

1. On the Tools menu, choose Export Alias File.

2. On the Export RSLogix 5000 Aliases dialog box, enter the FileName,

location, Alias Prefix, Base Tag, and RIO Output Placeholders.

Field Description

FileName Use the browse button ‘…’ to change the file location. Alias Prefix Use to distinguish between aliases for different 1756-RIO modules and to help identify groups of data items. If

you have multiple 1756-RIO modules in the RSLogix 5000 project, assign each module a unique Alias Prefix so

that the tags for each one are unique. Base Tag Use the base tag to identify the 1756-RIO module location in the ControlLogix chassis. RIO Output Placeholders Use this set of aliases when the 1756-RIO module is set to Monitor mode. These output placeholders aliases

point to a ControlLogix internal array. If you are using Monitor mode, you can write your new application to

write to this placeholder array and compare the monitored outputs to the outputs written by the new control

program. If you don’t want the aliases, leave the box unchecked. RIO Output Placeholders

Base Tag

Include BTW Configuration Words

This tag must be created by the user in the ControlLogix control program and must be an integer array of 10

RioTempOut elements (0…9), each with 255 sub-elements (0…254). So, RioTempOut would be

RioTempOut[0,0] to RioTempOut[9,254].

Check this box if you choose to include aliases for block transfer write configuration data.

3. Click OK.

Link Module Configuration with RSLogix 5000 Project Chapter 4

Use Monitor Mode to Upgrade an Existing System to a ControlLogix System

To upgrade an existing system, such as a PLC-5, PLC-3, or SLC system, to a ControlLogix system, you have to perform these steps.

1. Monitor the network in adapter mode.

2. Write the new control program in RSLogix 5000 programming software

to write to the internal array.

3. Compare the existing system’s outputs with the ControlLogix outputs, using the same live inputs.

4. Once both systems write the same outputs and have the same timing, switch over to the RSLogix 5000 control program for control.

Now it’s writing the real outputs instead of the placeholder array, using the 1756-RIO module to scan the network.

You could use the same 1756-RIO module to monitor and scan the network. You would have to download the scanner firmware after you compare the systems using the module in adapter mode to monitor the network. Or, you could use two 1756-RIO modules; one as a scanner, and one as an adapter on the Remote I/O network.

The following example breaks down the process. It explains using the 1756RIO module:

• as an adapter and its configuration in the configuration tool’s I/O tree.

• with the configuration tool to create the aliases based on the I/O

configuration tree.

• configuration tool’s process of exporting aliases to convert an existing system to a ControlLogix system using the module in scanner mode.

Create a Network Configuration and Export Aliases

Follow these steps to create a network configuration in the configuration tool and to create the aliases based on that configuration.

1. Set the 1756-RIO module to adapter mode.

See Launch the Configuration Tool and Select the Module Mode

page 30.

2. Create the network configuration in the configuration tool’s tree for the 1756-RIO module in adapter mode.

Monitored outputs include outputs to monitored racks and outputs to active racks.

3. Export the alias file. Once the network configuration is complete in the configuration tool, from the Tools menu, choose Export Alias File.

The following graphic and tables show how the configuration tool creates aliases based on the I/O configuration from the tree.

RIO_O010 Rack-01 Grp-0 Discrete Output - Place Holder RioTempOut[0, 22] RIO_O011 Rack-01 Grp-1 Discrete Output - Place Holder RioTempOut[0, 23]

4. Write a ControlLogix control program in the RSLogix 5000 project to write outputs to the placeholder array, then compare the outputs to the monitored outputs from the existing system.

5. Change the 1756-RIO module to scanner mode; or use an existing 1756RIO scanner.

See Launch the Configuration Tool and Select the Module Mode

page 30.

6. Export a scanner configuration and download it to the scanner.

7. Create aliases with the scanner configuration tool using the same

prefixes.

8. Import the aliases into the RSLogix 5000 project.

RIO_I001 Rack-00 Grp-1 Discrete Input Local:0:I0.Data[3]

RIO_O001 Rack-00 Grp-1 Discrete Output Local:0:O0.Data[3]

Notice that the alias names for the discrete outputs in the Export Alias Creation table are the same as the alias names for the placeholders in the Alias Creation for a Scanner in the ControlLogix Chassis table, but now point to I/ O outputs.

For example, an application that used alias name RIO_0001 wrote to placeholder location RioTempOut[0, 13], but would now write to the discrete outputs at Local:0:O0:Data[3].

Monitor Remote I/O

Chapter

Introduction

Now that the module configuration is complete and downloaded to the 1756RIO module, you are ready to scan a Remote I/O network.

Remote I/O scanning uses a 1756-RIO scanner in a local or remote chassis and multiple adapters on a Remote I/O network. The scanner enables communication between a ControlLogix controller and the remote I/O devices. The 1756-RIO scanner continually gathers and sends information to and from remote adapters on the Remote I/O network and sends that information to the ControlLogix controller in the chassis.

Remote I/O monitoring uses a 1756-RIO module in adapter mode to ‘listen’ to remote I/O and communicate that I/O back to the ControlLogix controller.

Within the configuration tool there are four utilities to monitor I/O:

• DiscMon monitors discrete input and output data

• BtMon monitors block transfers

• DiagMon monitors diagnostic counters

• LogMon monitors the scanner log

In this chapter, you will:

• use scan and monitor modes.

• monitor remote I/O discrete inputs and outputs in scanner mode.

• monitor remote I/O discrete inputs and outputs in adapter mode.

• monitor block transfers.

• export scanner configurations.

• use the diagnostic utilities in the configuration software to monitor,

save, and clear diagnostics.

Monitor Remote I/O Chapter 5

Scan Mode and Monitor Mode

The 1756-RIO module can perform various scan functions depending on whether it is a scanner or an adapter.

Scan Remote I/O in Scanner Mode

There are three scan modes of the ControlLogix controller. The following list explains each mode and what the 1756-RIO module does in each mode:

• Run mode

• Program mode

• Test mode

In run mode, the 1756-RIO module scans remote racks, reads discrete inputs, does not enable outputs to run on, and does not update block transfers.

In program mode, the 1756-RIO module scans remote racks, reads discrete inputs, but does not write discrete outputs, or update block transfers.

In test mode, the 1756-RIO behaves the same as it does in program mode, with the exception of the controller actively scanning the ladder logic.

Publication 1756-UM534B-EN-P - November 2010 99

Chapter 5 Monitor Remote I/O

TIP

Monitor Remote I/O in Adapter Mode

The 1756-RIO module provides utilities to upgrade an existing remote I/O application to a ControlLogix system with a minimum of downtime and startup time. This function is referred to as Monitor mode.

Used in Monitor mode, the 1756-RIO adapter can be used to upgrade a PLC5, PLC-3, or SLC system to a ControlLogix system by providing discrete inputs and outputs, and Block Transfer read and write data, to the controller. You can replace the existing application, or control program, that’s running on a PLC-5, PLC-3, or SLC system with a new application that runs on a ControlLogix controller using the 1756-RIO module as the remote I/O scanner.

The replacement system must be tested before the switchover. It uses the same field wiring as the old system. If unanticipated problems arise, you can switch back to the old system in minutes.
