• A 1769-ECR right end cap or 1769-ECL left end cap is required to
terminate the end of the communication bus.
ATTENTION
This controller has a network access port (NAP) for temporary connections to
the ControlNet network. Do not plug a DH-485 network cable or an RJ45
connector for EtherNet/IP networks into the NAP. Undesirable behavior and/or
damage to the port may result.
Set the Node Address
Every ControlNet network requires at least one module that can store
parameters and configure the network with those parameters upon startup.
The CompactLogix controller is called a keeper because it keeps the network
configuration.
The CompactLogix controller can keep the network parameters at any legal
node address (01…99). Multiple devices on any one network can act as the
network keepers. Each device capable of being the network keeper acts to
back up the current keeper. This back-up function is automatic and requires
no action on your part.
Node address switches are set to the 99 position at shipment, as shown in the
figure.
Use these steps to set the node address.

Panel Mounting
Mount the controller to a panel by using two screws per module. Use M4 or
#8 panhead screws. Mounting screws are required on every module.
IMPORTANT
The grounding tab, located where you install the mounting screws, enables
the module to be grounded when it is panel-mounted.
This procedure lets you use the assembled modules as a template for drilling
holes in the panel. Due to module mounting-hole tolerance, it is important to
follow these procedures.
1. On a clean work surface, assemble no more than three modules.
2. Using the assembled modules as a template, carefully mark the center
of all module-mounting holes on the panel.
3. Return the assembled modules to the clean work surface, including
any previously mounted modules.
4. Drill and tap the mounting holes for the recommended M4 or #8
screw.
5. Place the modules back on the panel and check for proper hole
alignment.

6. Attach the modules to the panel by using the mounting screws.
IMPORTANT
If mounting more modules, mount only the last one of this group and put the
others aside. This reduces remounting time when you are drilling and
tapping the next group of modules.
7. Repeat steps 1…6 for any remaining modules.
DIN-rail Mounting
The controller can be mounted by using the following DIN rails:
• EN 50 022 - 35 x 7.5 mm (1.38 x 0.30 in.)
• EN 50 022 - 35 x 15 mm (1.38 x 0.59 in.)
Before mounting the controller on a DIN rail, close the DIN rail latches.
Press the DIN rail mounting area of the controller against the DIN rail. The
latches will momentarily open and lock into place.
ATTENTION
This product is intended to be mounted to a well-grounded mounting surface,
such as a metal panel. Additional grounding connections from the controller’s
grounding tab or DIN rail (if used) are not required unless the mounting
surface cannot be grounded.
Refer to Industrial Automation Wiring and Grounding Guidelines,
Allen-Bradley publication 1770-4.1, for additional information.
This product is grounded through the DIN rail to chassis ground. Use zinc
plated yellow-chromate steel DIN rail to assure proper grounding. The use of
other DIN rail materials (for example, aluminum and plastic) that can corrode,
oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately.

Connect the Controller to the Network Via a ControlNet Tap
Typically, ControlNet taps are used to make permanent connections from the
CompactLogix controller to the network. Perform the following steps to
connect the module to the network by using a ControlNet tap.
ATTENTION
Do not allow any metal portions of the tap to contact any conductive material.
If you disconnect the tap from the module, place the dust cap back on the
straight or right angle connector to prevent the connector from accidentally
contacting a metallic grounded surface.

Install the Appropriate Electronic Data Sheet (EDS) Files
If you have RSLinx software, version 2.43 or greater, the most current EDS
files were installed with the software. If you are using RSLinx software,
version 2.42 or later, you might need to install EDS files. You need EDS files
for the following:
• 1769-L32C controller
• 1769-L32C ControlNet port
• 1769-L35CR controller
• 1769-L35CR ControlNet port
• 1769 CompactBus
• 1769 local adapter
All of these EDS files, except for the 1769 CompactBus file, are updated for
each firmware revision. There is also a revision 1.x of the EDS files that you
need for new controllers. Each controller ships with revision 1.x firmware.
To update the firmware, you must have these revision 1.x EDS files installed:
• 0001000E00500100.eds for the controller
• 0001000C00A00100.eds for the ControlNet port
The EDS files are available on the CD for RSLogix 5000 Enterprise Series
software, version 13. The files are also available at
http://www.ab.com/networks/eds

Load the Controller Firmware
The controller ships without working firmware. You must download the
current firmware before you can use the controller. To load firmware, you can
use:
• ControlFlash utility that ships with RSLogix5000 software.
• AutoFlash that starts through RSLogix5000 software when you try to
download a project and the controller does not have the current
firmware.
• 1784-CF64 CompactFlash card with valid memory already loaded.
The firmware is available with RSLogix 5000 software or you can download it
from the support website by using these steps.
1. Go to http://support.rockwellautomation.com
2. In the left column (frame), click Technical Support and Firmware
Updates.
3. Select the firmware revision.
The download process requires you to enter the serial number of your
RSLogix 5000 programming software.
If you load (flash) controller firmware via the ControlFlash or AutoFlash
utilities, you need either a serial or ControlNet connection to the controller.
Flashing via a ControlNet connection is faster than the serial connection.

Interpret Status Indicators as Related to the ControlNet Network
Use the Module Status and Network Status indicators to determine how your
CompactLogix controller is operating on the ControlNet network.
These status indicators provide information about the controller and the
network when the controller is connected to the ControlNet network via the
BNC connectors and describes the possible conditions for module and
network status indicators.
Indicator Condition Description
Steady The indicator is on continuously in the defined state.
Alternating Two indicators alternate between the two defined states at the
same time (applies to both indicators when viewed together);
the two indicators are always in opposite states, out of phase.
Flashing The indicator alternates between the two defined states
(applies to each indicator viewed independent of the other); if
both indicators are flashing, they flash together, in phase.
IMPORTANT
Keep in mind that the Module Status indicator reflects the module state (for
example, self-test, firmware update, normal operation but no connection
established). The network status indicators, A and B, reflect network status.
Remember that the host is able to engage in local messaging with the card
although it is detached from the network. Therefore, the Module Status
status indicator is flashing green if the host has successfully started the
card. Note, however, that until the host removes reset, all status indicators
on the daughtercard remain off.
When you view the indicators, always view the Module Status indicator
first to determine the state of the daughtercard. This information may help
you to interpret the Network Status indicators. As a general practice, view
all status indicators (Module Status and Network Status) together to gain a
full understanding of the daughtercard’s status.
