Chapter 1 Install a 1756 EtherNet/IP Communication Module

Install the Module

Follow these steps to install the module.

1. Align the circuit board with top and bottom guides in the chassis.

2. Slide the module into the chassis.

WARNING: When you insert or remove the module while backplane power is

on, an electric arc can occur. An electrical arc can cause an explosion in

hazardous location installations.

Be sure that power is removed or the area is nonhazardous before proceeding.

Repeated electrical arcs causes excessive wear to contacts on both the module and

its mating connector. Worn contacts can create electrical resistance that can affect

module operation.

ATTENTION: Use caution when handling the module. One side of the module is

a heat sink and can be hot.

IMPORTANT

Your module resembles one of the modules that are shown in the illustrations. The

extreme temperature (XT) versions of the modules are not shown in the

illustrations.

Make sure that the module backplane connector properly connects to the

chassis backplane. The module is properly installed when it is flush with

the power supply or other installed modules.

Connect the Module

Use the following information to wire the module.

Connect the Module to an EtherNet/IP Network Via an RJ45

Connection

Wire the RJ45 connector as shown.

Follow these steps to connect the module to the network.

WARNING: If you connect or disconnect the communication cable with power

that is applied to this module or any device on the network, an electric arc can

occur. An electric arc can cause an explosion in hazardous location

Connect to the Module Via

the USB Port

If the module has a USB port, is it a Type B receptacle. To use the USB port, you

must have RSLinx® Classic software, version 2.55 or later, installed on your

computer.

Use a USB cable to connect your computer to the USB port. You can download

programs to controllers and configure Ethernet modules directly from your

computer over a USB connection.

For more information about USB setup and configuration, see Chapter 6, USB

Communication on page 59.

Apply Chassis Power and

Check Status Indicators

Before you apply power, you must install and connect a ControlLogix chassis and

power supply.

Follow these steps to apply power.

1. Flip the switch to the ON position.

WARNING: Do not use the USB port in hazardous locations.

ATTENTION: The USB port is intended for temporary local programming

purposes only and not intended for permanent connection. The USB cable is not

to exceed 3.0 m (9.84 ft) and must not contain hubs. The USB cable can be

ordered from Rockwell Automation, catalog number 9300-USBCBL-ABHR.

2. To determine that the power supply and module are operating properly,

check the power supply and Module Status indicators and alphanumeric

display.

The alphanumeric display cycles through the following states: TEST -

PASS - OK - REV x.x, where x.x is the firmware revision of the module.

The display then alternates between OK and port link status for both

ports.
