Before You Begin

Use this document as a guide for installing and powering-up your 1769-L32C
or 1769-L35CR CompactLogix controller. You should already be familiar with
the system components.

You mus flash upgrade the firmware on your CompactLogix controller before
you can use it. The controller ships with firmware revision 1.x but must be
upgraded to match the version of RSLogix5000 software that you are using.
For example, if you are using RSLogix5000 software, version 13, you must
upgrade your CompactLogix controller firmware to revision 13.x before
using it.

Be sure you have all components, noting the table that shows the components
that ship with the controller.

IMPORTANT

You can also use these components with the controller:

• 1784-CF64 or 1784-CF128 Industrial CompactFlash card to add
nonvolatile memory

• 1756-CP3 or 1747-CP3 serial cable to connect a device to the
RS-232 port

• Either of the following to connect to the ControlNet network:

• ControlNet taps for connections from controller channels A or B

to the ControlNet network

• 1786-CP cable for connections from a programming terminal to
the ControlNet network via the controller’s network access
port (NAP)

Consider the following when planning your CompactLogix system:

• The CompactLogix controller is always the leftmost module in the
system.

• The CompactLogix controller must be located within four modules of
the power supply.

• Some I/O modules can be located up to eight modules away from the
power supply; see the documentation for your 1769 I/O modules
for details.

• The 1769-L32C controller supports as many as 16 I/O modules in a
maximum of 3 I/O banks with 2 expansion cables.

• The 1769-L35CR controller supports as many as 30 I/O modules in a
maximum of 3 I/O banks with 2 expansion cables.

• Each I/O bank requires its own power supply.

• Only one controller can be used in a CompactLogix system.

• 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.
