(2) CompactLogix 5370 L2 controllers have an embedded power supply. Therefore, you do not need to consider power supply distance rating when installing the controller. The Compact I/O modules that
are used as local expansion modules in a CompactLogix 5370 L2 control systems operate on a CompactBus. TheseCompact I/O modules also have a power supply distance rating that you must consider
when installing those modules.
For more information on power supply distance rating regarding how to use Compact I/O modules in a CompactLogix 5370 L2 control system, see page 123 and page 220.
(3) IMPORTANT: You can use up to the maximum number of 1734 POINT I/O modules with the CompactLogix 5370 L1 controllers that are listed in Table 3. This applies only as long asthe total current that
the modules draw does not exceed the available POINTBus™ backplane current of 1 A. If you must use more local expansion modules than the POINTBus backplane current supports, you can install a
1734-EP24DC POINT I/O expansion power supply between local expansion modules to increase the POINTBus backplane power and meet your system requirements.

Chapter 1 CompactLogix 5370 Controllers Overview
The 1769-L30ER-NSE controller is intended for use in applications that
require the installed controller to deplete its residual stored energy to specific
levels before transporting it into or out of your application.
.
Some applications require that the installed controller to deplete its residual
stored energy to specific levels before transporting it into or out of your
application. This requirement can include other devices that also require a wait
time before removing them. See the documentation of those products for more
information.
Support for Integrated Motion over an EtherNet/IP Network
The following CompactLogix 5370 controllers support Integrated Motion
over an EtherNet/IP network:
• 1769-L18ERM-BB1B
• 1769-L27ERM-QBFC1B
• 1769-L30ERM
• 1769-L33ERM
• 1769-L33ERMO
• 1769-L36ERM
• 1769-L36ERMO
• 1769-L37ERM
• 1769-L37ERMK
• 1769-L37ERMO(1)
• 1769-L38ERM
• 1769-L38ERMK
• 1769-L38ERMO(1)
WARNING: If your application requires the 1769-L30ER-NSE controller to
deplete its residual stored energy to 200 J or fewer before you transport it
into or out of the application, complete these steps before you remove the
controller.
1. Turn off power to the chassis.
After you turn off power, the controller’s OK status indicator transitions
from Green to Solid Red to OFF.
2. Wait at least 15 minutes for the residual stored energy to decrease to
200 J or fewer before you remove the controller.
There is no visual indication of when the 15 minutes has expired.You
must track that time period.
IMPORTANT The Real Time Clock (RTC) does not retain its time and date when the power
is off.

Application on page 283.
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.
The following Electronic Keying options are available.
Carefully consider the implications of each keying option when selecting one.
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.
Keying Option Description
Compatible
Module 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:
•Samecatalognumber
• 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.
Disable Keying Indicates that the keying attributes are not considered when attempting to communicate 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.
Exact Match Indicates that all keying attributes must match to establish communication. If any attribute
does not match precisely, communication with the device does not occur.
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.
