Preface

Studio 5000 Environment

The Studio 5000 Automation Engineering & Design Environment™ combines engineering and design elements into a common environment. The first element in the Studio 5000® environment is the Studio 5000 Logix Designer™ application. The Logix Designer application is the rebranding of RSLogix™ 5000 software and continues to be the product to program Logix5000™ controllers for discrete, process, batch, motion, safety, and drive-based solutions.

ControlLogix Controllers Overview

The Studio 5000 environment is the foundation for the future of Rockwell Automation® engineering design tools and capabilities. This environment is the one place for design engineers to develop the elements of their control system.

There are three types of ControlLogix® controllers available. These types include the following:

• Standard ControlLogix controllers

• Extreme environment ControlLogix controllers

• GuardLogix® controllers

This manual explains how to use standard and extreme environment ControlLogix controllers.

IMPORTANT

TIP

IMPORTANT

Allow the ESM to finish charging before removing power from the controller. Failure to do so can result in the loss of the application program. A type 1, code 40 major fault is logged on powerup.

To verify that the ESM is fully charged, check the status display to confirm that messages CHRG or ESM charging are no longer indicated.

We recommend that you check the WallClockTime object attributes after installing an ESM to verify that time of the controller is correct.

The ESM contains a real-time clock. If the ESM is new or came from another controller, the WallClockTime object attributes for your controller can change.

Uninstall the ESM

WARNING: If your application requires the ESM to deplete its residual stored

energy to 40 μJoule or less before you transport it into or out of the application, use only the 1756-(SP)ESMNSE(XT) module. In this case, complete these steps before you remove the ESM.

• Turn power off to the chassis.

After you turn power off to the chassis, the controller’s OK status indicator transitions from green to solid red to OFF.

• Wai t at least 20 minutes for the residual stored energy to decrease to 40 μJoule or less before you remove the ESM.

There is no visual indication of when the 20 minutes has expired. You must trac k

that time period.

WARNING: When you insert or remove the energy storage module while

backplane power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations.

Be sure that power is removed or the area is nonhazardous before proceeding. Repeated electrical arcing causes excessive wear to contacts on both the module and its mating connector.

Before you remove an ESM, make necessary adjustments to your program to account for potential changes to the WallClockTime attribute.

Consider these points before removing the ESM:

• The following ESM modules can be currently installed in your 1756-L7x or 1756-L7xXT controller:

– 1756-ESMCAP – 1756-ESMNSE – 1756-ESMCAPXT – 1756-ESMNSEXT

• After the 1756-L7x or 1756-L7xXT controllers lose power, because the chassis power is turned off or the controller has been removed from a powered chassis, do not immediately remove the ESM.

Wait until the OK status indicator on the controller transitions from Green to Solid Red to OFF before you remove the ESM.

• You can use the 1756-ESMNSE module with only a 1756-L73 (8 MB) or smaller memory-sized controller.

• Use the 1756-ESMNSE module if your application requires that the installed ESM deplete its residual stored energy to 40 μJoule or less before transporting it into or out of your application.

• Once it is installed, you cannot remove the 1756-ESMNRM or 1756-ESMNRMXT module from a 1756-L7x or 1756-L7xXT controller.

Complete these steps to remove an ESM module from the controller.

1. Remove the key from the mode switch.

The next step depends on which of the following conditions applies to your application.

• If you are removing the ESM from a powered 1756-L7x controller, go to

step 2

• If you are removing the ESM from a 1756-L7x controller that is not powered, because the chassis power is turned off or the controller has been removed from a powered chassis, do not immediately remove the ESM.

Wait until the OK status indicator on the controller transitions from Green to Solid Red to OFF before you remove the ESM.

Then the controller is off 52% of the time:

• Total hours per week = 7 x 24 = 168 hrs

• Total off hours per week = (5 days x 8 hr/day) + Saturday +

Sunday = 88 hrs

• Percentage off time = 88/168 = 52%

3. Determine the estimated worst-case battery life before and after the BAT status indicator turns on.

4. For each year of battery life, decrease the time before the BAT status indicator turns on by the percentage that is shown in the table.

Do not decrease the time after the BAT status indicator turns on.

If the BAT status indicator turns on when you apply power to the controller, the remaining battery life can be less than Tab le 7

indicates. Some of the battery life can be used up while the controller is off and unable to turn on the BAT status indicator.

1756-BATM Battery Module and Battery Life

Use the 1756-BATM battery module with any 1756-L6x/A controller. The battery module is highly recommended for higher-memory controllers.

If your project is not stored in nonvolatile memory, the use of the battery module is highly recommended.

When the 1756-BATA battery within the 1756-BATM module is approximately 50% discharged, these low-battery warnings are indicated:

• The BAT is solid red.

• A minor fault (type 10, code 10) is logged.

EXAMPLE

Estimate 1756-BA2 Battery Life After Warnings

Use this table to estimate the battery life after the low-battery warnings are indicated. Use these times even if the controller does not have power because there is a small power-drain on the battery.

When you power up the controller, see if there is a low-battery warning. If you get a low-battery warning for the first time, you have less battery life than this table shows. While powered down, the controller still drains the battery but it cannot give the low-battery warning.

(1)

(1) These nonvolatile memory cards are optional and do not come with the controller.

The 1756-L7x controllers ship with an SD card installed. We recommend that you leave the SD card installed, so if a fault occurs, diagnostic data is automatically written to the card and Rockwell Automation can use the data to troubleshoot the anomaly.

We recommend that you use the SD cards available from Rockwell Automation (catalog numbers 1784-SD1 or 1784-SD2).

While other SD cards can be used with the controller, Rockwell Automation has not tested the use of those cards with the controller. If you use an SD card other than those cards that are available from Rockwell Automation, you can experience data corruption or loss.

Also, SD cards that are not provided by Rockwell Automation can have different industrial, environmental, and certification ratings as those cards that are available from Rockwell Automation and can have difficulty with survival in the same industrial environments as the industrially rated versions available from Rockwell Automation.

Electronic Keying

Electronic Keying reduces the possibility that you use the wrong device in a control system. It compares the device that is defined in your project to the installed device. If keying fails, a fault occurs. These attributes are compared.

Attribute Description

Vendor The device manufacturer.

Device Type The general type of the product, for example, digital I/O module.

Product Code The specific type of the product. The Product Code maps to a catalog number.

Major Revision A number that represents the functional capabilities of a device.

Minor Revision A number that represents behavior changes in the device.

The following Electronic Keying options are available.

Keying Option Description

Compatible Module

Disable Keying Indicates that the keying attributes are not considered when attempting to communicate with a

Exact Match Indicates that all keying attributes must match to establish communication. If any attribute does

Lets the installed device accept the key of the device that is defined in the project when the installed device can emulate the defined device. With Compatible Module, you can typically replace a device with another device that has the following characteristics:

• Same catalog number

• Same or higher Major Revision

• Minor Revision as follows: – If the Major Revision is the same, the Minor Revision must be the same or higher. – If the Major Revision is higher, the Minor Revision can be any number.

device. With Disable Keying, communication can occur with a device other than the type specified in the project.

ATT EN TI ON : Be extremely cautious when using Disable Keying; i f used incorrectly, this option can lead to personal injury or death, property damage, or economic loss.

We strongly recommend that you do not use Disable Keying. If you use Disable Keying, you must take full responsibility for understanding whether the device

being used can fulfill the functional requirements of the application.

not match precisely, communication with the device does not occur.

Carefully consider the implications of each keying option when selecting one.

Changing Electronic Keying parameters online interrupts connections to the device and any devices that are connected through the device. Connections from other controllers can also be broken.

If an I/O connection to a device is interrupted, the result can be a loss of data.

EtherNet/IP Network Communication

The EtherNet/IP network offers a full suite of control, configuration, and data collection services by layering the Common Industrial Protocol (CIP) over the standard internet protocols, such as TCP/IP and UDP. This combination of well-accepted standards provides the capability that is required to support information data exchange and control applications.

The EtherNet/IP network uses commercially available Ethernet components and physical media, providing you with a cost-effective plant-floor solution.

Connections Over an EtherNet/IP Network

You indirectly determine the number of connections the controller uses by configuring the controller to communicate with other devices in the system. Connections are allocations of resources that provide more reliable communication between devices as compared to unconnected messages.

All EtherNet/IP connections are unscheduled. The requested packet interval (RPI) for I/O control or the program, such as a MSG instruction triggers an unscheduled connection. Unscheduled messaging lets you send and receive data when needed.

Double Data Rate (DDR) Backplane Communication

DDR communication can be achieved with the 1756-L7x controller. The following communication modules support DDR when used with the 1756-L7x controller. Minimum series are indicated as follows:

• 1756-EN2T/C

• 1756-EN2TR/B

• 1756-EN2TF/B

• 1756-EN2TXT/C

• 1756-EN3TR/A

• 1756-RM/B

DDR communication is achieved most efficiently when all modules in the communication path are DDR modules, or, in other words, as one conversation (connection) only between DDR modules.

DDR communication is achievable in a chassis with a mix of DDR and nonDDR modules. The DDR communication occurs between the modules that

88 Rockwell Automation Publication 1756-UM001O-EN-P - October 2014

Communication Networks Chapter 5

support it. If non-DDR modules are also in the chassis, communication between those modules is at the non-DDR rate.

For example, you can have a chassis with two 1756-L7x controllers in slots 0 and 1 communicating with each other by using DDR, and two 1756-L6x controllers in slots 2 and 3 communicating by using non-DDR.

When multicast communication is used within a chassis to multiple modules, the transmission rate is limited to the slowest module—or at the non-DDR rate.

For example, if a 1756-L7x controller is producing a tag to a 1756-L7x controller and a 1756-L6x controller on the same multicast connection, it must use the non-DDR rate.

ControlNet Network Communication

The ControlNet network is a real-time control network that provides high-speed transport of time-critical I/O and interlocking data and messaging data. This includes the upload and download of program and configuration data on one physical-media link. The highly efficient data transfer capability of the ControlNet network significantly enhances I/O performance and peer-to-peer communication in any system or application.

The ControlNet network is highly deterministic and repeatable and is unaffected when devices are connected or disconnected from the network. This quality results in dependable, synchronized, and coordinated real-time performance.

The ControlNet network often functions as the following:

• A substitute/replacement for the remote I/O (RIO) network because the ControlNet network adeptly handles large numbers of I/O points

• A backbone for multiple distributed DeviceNet networks

• A peer interlocking network

Chapter 5 Communication Networks

Connections Over a ControlNet Network

You indirectly determine the number of connections the controller uses by configuring the controller to communicate with other devices in the system. Connections are allocations of resources that provide communication between devices as compared to unconnected messages.

Table 17 - ControlNet Connections

Connection Definition

Scheduled (unique to a

Control Net network)

Unscheduled An unscheduled connection is a message transfer between devices that the requested packet

A scheduled connection is unique to ControlNet communication. A scheduled connection lets you send and receive data repeatedly at a predetermined interval, which is the requested packet interval (RPI). For example, a connection to an I/O module is a scheduled connection because you repeatedly receive data from the module at a specified inter val.

Other scheduled connections include connections to the following:

• Communication devices

• Produced/consumed tags

On a ControlNet network, you must use RSNetWorx for ControlNet software to enable all scheduled connections and establish a network update time (NUT). A scheduled connection reserves network bandwidth specifically to handle the connection.

interval (RPI) or the program, such as a MSG instruction, triggers. Unscheduled messaging allows you to send and receive data when you must:

Unscheduled connections use the remainder of network bandwidth after scheduled connections are allocated.

DeviceNet Network Communication

ControlNet Module Connections

The 1756-CNB and 1756-CNBR communication modules support 64 CIP connections over a ControlNet network. However, for optimal performance, configure a maximum of 48 connections for each module.

The 1756-CN2, 1756-CN2R, and 1756-CN2RXT communication modules support 128 connections over a ControlNet network, all of which can be configured without risk of performance degradation.

The DeviceNet network uses the Common Industrial Protocol (CIP) to provide the control, configuration, and data collection capabilities for industrial devices. The DeviceNet network uses the proven Controller Area Network (CAN) technology, which lowers installation costs and decreases installation time and costly downtime.

A DeviceNet network provides access to the intelligence present in your devices by letting you connect devices directly to plant-floor controllers without having to hard-wire each device into an I/O module.

With a ControlLogix system, DeviceNet communication requires the use of a 1756-DNB DeviceNet communication module.

Connections Over DeviceNet Networks

The ControlLogix controller requires two connections for each 1756-DNB module. One connection is for module status and configuration. The other connection is a rack-optimized connection for the device data.

ControlLogix DeviceNet Module Memory

The 1756-DNB module has fixed sections of memory for the input and output data of the DeviceNet devices on the network. Each device on your network requires some input or output memory of the scanner. Some devices send and receive data, so they need input and output memory. The 1756-DNB module supports up to add the following :

• 124 DINTs of input data

• 123 DINTs of output data

lists the RIO modules and capabilities.

When a channel on the 1756-DHRIO or 1756-DHRIOXT module is configured for remote I/O, the module acts as a scanner for a universal remote I/ O network. The controller communicates to the module to send and receive the I/O data on the universal remote I/O network.

The 1756-RIO module can act as a scanner or adapter on a remote I/O network. The 1756-RIO module transfers digital, block transfer, analog, and specialty data without message instructions.

Figure 14 - ControlLogix Universal Remote I/O Communication Example

Communicate Over a Universal Remote I/O Network

For the controller to control I/O over a universal remote I/O network, you must complete these tasks.

Rockwell Automation Publication 1756-UM001O-EN-P - October 2014 97

Chapter 5 Communication Networks

1. Configure the remote I/O adapter.

2. Lay out the remote I/O network cable.

3. Connect the remote I/O network cable.

4. Configure the scanner channel.

For more information to configure a remote I/O network with the 1756-RIO, 1756-DHRIO, or 1756-DHRIOXT modules, see these publications:

• Data Highway Plus-Remote I/O Communication Interface Module User Manual, publication 1756-UM514

• ControlLogix Remote I/O Communication Module User Manual, publication 1756-UM534

As you design your remote I/O network, remember the following:

• All devices that are connected to a remote I/O network must communicate by using the same communication rate. These rates are available for remote I/O:

Foundation Fieldbus Communication

– 57.6 Kbps – 115.2 Kbps – 230.4 Kbps

• You must assign unique partial and full racks to each channel used in

Remote I/O Scanner mode.

Both channels of a 1756-DHRIO or 1756-DHRIOXT module cannot scan the same partial or full rack address. Both module channels can communicate to 00…37 octal or 40…77 octal, but each channel can communicate only with one address at a time in whichever of these two ranges it falls.

Foundation Fieldbus is an open interoperable fieldbus that is designed for process control instrumentation. The fieldbus devices that are described in Ta b l e 2 2

can be connected to the ControlLogix controller via another network as shown in the following example.
