Remove the SD Card

The 1756-L7x controller ships with an SD card installed. Complete these steps to remove the SD card from the 1756-L7x controller.

WARNING: When you insert or remove the Secure Digital (SD) memory card while 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.

IMPORTANT • 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.

TIP 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.

Install the ESM

To install an ESM in the 1756-L7x controller, complete these steps.

ATTENTION: To avoid potential damage to the product when inserting the ESM, align it in the track and slide forward with minimal force until the ESM snaps into place.

1. Align the tongue-and-groove slots of the ESM and controller.

2. Slide the ESM back until it snaps into place.

The ESM begins charging after installation. The following status messages indicate charging status:

•ESM Charging

•CHRG

26 Rockwell Automation Publication 1756-UM001P-EN-P - May 2017

Uninstall the ESM

Install the 1756-L7x Controller Chapter 1

After you install the ESM, it can take up to 15 seconds for the charging status messages to display.

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.

TIP 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.

WARNING: If your application requires the ESM to deplete its residual stored energy to 40 μJ 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.

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

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

track 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.

IMPORTANT Before you remove an ESM, make necessary adjustments to your program to

account for potential changes to the WallClockTime attribute.

Rockwell Automation Publication 1756-UM001P-EN-P - May 2017 27

Chapter 1 Install the 1756-L7x Controller

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

• 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 26.

• 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 μJ 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.

• The Armor™ controller energy storage modules (ESM) cannot be removed or replaced.

Use the Mode Switch to Change the Operation Mode

Use the mode switch to change the operation mode. The controller mode switch provides a mechanical means to enhance controller and control system security. You must physically move the mode switch on the controller to change its operating mode from RUN, to REM, or to PROG. When the mode switch on the controller is set to RUN mode, features like online editing, program downloads, and firmware upgrades are prohibited. See complete list of prohibited features.

The physical mode switch can complement other authorization and authentication methods that similarly control user-access to the controller, such as the following:

• Logix CPU Security tool

• FactoryTalk® Security service

IMPORTANT During runtime, we recommend that you place the controller mode switch in

RUN mode and remove the key (if applicable) from the switch. This can help discourage unauthorized access to the controller or potential tampering with the program of the controller, configuration, or device firmware. Place the mode switch in REM or PROG mode during controller commissioning and maintenance and whenever temporary access is necessary to change the program, configuration, or firmware of the product.

Check the Battery Status

When the battery is approximately 95% discharged, these low-battery warnings are indicated:

• The BAT is solid red.

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

IMPORTANT To prevent possible battery leakage, even if the BAT status indicator is off,

replace a battery according to this schedule.

If the temperature 2.54 cm (1 in.) below the chassis is

-25…35 C (-13…95 F) No replacement required

36…40 C (96.8…104 F) 3 years

To estimate how long a 1756-BA1 or 1756-BATA battery can support controller memory on 1756-L6x, series A controllers, perform this procedure.

1. Determine the temperature 2.54 cm (1 in.) below the chassis.

2. Determine the weekly percentage of time that the controller is turned on.

EXAMPLE If a controller is Off at one of these times:

• 8 hr/day during a 5-day work week

• All day Saturday and Sunday

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%

76 Rockwell Automation Publication 1756-UM001P-EN-P - May 2017

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.

IMPORTANT If the BAT status indicator turns on when you apply power to the

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

IMPORTANT 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.

IMPORTANT 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.

IMPORTANT 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.

ControlLogix System and Controllers Chapter 4

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 Lets the installed device accept the key of the device that is defined in the project when

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

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

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.

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

ATTENTION: Be extremely cautious when using Disable Keying; if 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.

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

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

IMPORTANT

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.

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

• 1756-RM2/A

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.

92 Rockwell Automation Publication 1756-UM001P-EN-P - May 2017

Communication Networks Chapter 5

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

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 interval.

Other scheduled connections include connections to the following:

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

1756-DHRIO • Function as a remote I/O (RIO) scanner.

• Suppor t 32 logical rack connections or 16 block transfer connections per channel.

• Establish connections between controllers and I/O adapters.

• Distribute control so that each controller has its own I/O.

1756-DHRIOXT • Function as a remote I/O (RIO) scanner.

• Suppor t 32 logical rack connections or 16 block transfer connections per channel.

• Establish connections between controllers and I/O adapters.

• Distribute control so that each controller has its own I/O.

• Operate in extreme environments with -25…70 °C (-13…158 °F) temperatures.

Table 28 lists the DH+ modules and capabilities.

For DH+ network communication, use a 1756-DHRIO or 1756-DHRIOXT module in the ControlLogix chassis to exchange information between these controllers:

• PLC and SLC™ controllers

• ControlLogix controllers and PLC or SLC controllers

• ControlLogix controllers

The DH+ network also provides the following:

• Data exchange between controllers

• Plant-wide data sharing

• Cellular level data sharing

You can connect a maximum of 32 stations to one DH+ link:

• Channel A supports 57.6 Kbps, 115.2 Kbps, and 230.4 Kbps.

• Channel B supports 57.6 Kbps and 115.2 Kbps.

Communicate Over a DH+ Network

For the controller to communicate to a workstation or other device over a DH+ network, use RSLinx Classic software to do the following:

• Specify a unique link ID for each ControlLogix backplane and additional network in the communication path.

• Configure the routing table for the 1756-DHRIO or 1756-DHRIOXT module.

The 1756-DHRIO or 1756-DHRIOXT module can route a message through up to four communication networks and three chassis. This limit applies only to the routing of a message and not to the total number of networks or chassis in a system.

For more information to configure and use a DH+ network via the 1756-DHRIO or 1756-DHRIOXT module, see the Data Highway PlusRemote I/O Communication Interface Module User Manual, publication
