• 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.

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 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.
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.

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.
1. Remove and save the dust caps from the ControlNet taps.

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
Alternating
The indicator is on continuously in the defined state.
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.
