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

Insert the Controller into the Chassis

When installing a ControlLogix controller, you can do the following:

• Place the controller in any slot.

• Use multiple controllers in the same chassis.

You can install or remove a ControlLogix controller while chassis power is on and the system is operating.

WARNING: When you insert or remove the 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 controller and its mating connector on the chassis. Worn contacts may create electrical resistance that can affect controller operation.

ATTENTION: Prevent Electrostatic Discharge

This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines when you handle this equipment:

• Touch a grounded object to discharge potential static.

• Wear an approved grounding wriststrap.

• Do not touch connectors or pins on component boards.

• Do not touch circuit components inside the equipment.

• Use a static-safe workstation, if available.

• Store the equipment in appropriate static-safe packaging when not in use.

The ESM begins charging when one of these actions occurs:

• The controller and ESM are installed into a powered chassis.

• Power is applied to the chassis that contains a controller with the ESM

installed.

• An ESM is installed into a powered controller.

After power is applied, the ESM charges for up to two minutes as indicated by CHRG or ESM Charging on the status display.

• Verify that the SD card status indicator is off and that the card is not in use before removing it.

• We recommend that you do the following:

–Leave an SD card installed. – Use the SD cards available from Rockwell Automation (catalog number

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 do not have the same industrial, environmental, and certification ratings as those cards that are available from Rockwell Automation.

1. Verify that the SD card is not in use by checking to be sure that the SD indicator is Off.

You can also put the controller into Hard Run mode to keep the controller from writing to the SD card while it is removed.

2. Open the door to access the SD card.

3. Press and release the SD card to eject it.

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

Chapter 1 Install the 1756-L7x Controller

IMPORTANT

• The 1756-L7x controllers come with the 1756-ESMCAP module installed. The 1756-L7xXT extreme temperature controller ships with a 1756-ESMCAPXT module installed. For more information on how to use a 1756-ESMNSE, 1756-ESMNRM, 1756-ESMNSEXT, or 1756-ESMNRMXT module, see page 28

• 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.

After the OK status indicator transitions to Off, go to step 2
