Quick Start Guide For Configuring NX-EIC202 With Rockwell Automation

1 Introduction
This document shows the basic steps for configuration of a Rockwell Automation PLC to connect to the OMRON NX-EIC202 Ethernet/IP coupler. The guide will assume the hardware installation has already been completed following [1].

This document has been made using the Allen-Bradley 1769-L23E-QB1 Controller, but will apply to other Rockwell based controllers as well.

The following is required:
  1. OMRON NX-EIC202 EDS file
  2. Rockwell Automation RSLogix5000 tool
  3. OMRON Sysmac Studio NX-I/O edition
Please be sure to read the related manuals to use the NX-EIC202 Unit safely and properly.
Reference Name Cat. No.
[1] NX-Series EtherNet/IP Copuler Unit User's Manual W536

Use the following procedure to prepare the Unit for use. Refer to the reference sections for details on the indicated steps.

Step Item Section
1 Installation: Install the EDS file in Logix5000 2.1
2 Set IP address using rotary switches 2.2
3 Configure the NX-EIC202 NX Configuration using Sysmac Studio 2.3
4 [Optional]Set software IP address / Set NTP server Appendix A
5 Configure EIP connection 2.4
6 Use NX-EIC202 IO data in PLC program 3

2.1 [RSLogix] Install EDS File

Follow the steps below to install (a new version of) an EDS file within RSLogix5000. Both installation as de-installation of the EDS file is done by the EDS Hardware Installation Tool (Tools menu).


  1. To delete the old EDS file, select the Unregister a device option.


  1. To Install the new EDS file, select the Register an EDS file(s).


2.2 Setting the NX-EIC202 IP Address

Perform the following steps to change the IP address of the Unit in the Rockwell default range (192.168.1.x).

  1. Set the DIP Switch 4 to On.
  2. Set the two rotary switches to the desired IP address (last octet 01 to FE for to

After a power toggle, the new IP address will be active in the Unit.

Please find additional information about setting IP address in [1], section 9-4.

2.3 [Sysmac Studio] Setting up the Slave Terminal

The NX-EIC202 Operation Manual (see [1]) describes the procedure to configure the Slave Terminal (NX-EIC202 and the individual NX Units).
Connect Sysmac Studio using USB connection and configure the NX configuration with the information of the following two sections of the original manual:

  • Section 9-2 Setting Slave Terminal Parameters
  • Section 9-3 Transferring and Comparing Settings

After the NX Configuration is finished, please use the following steps to check the resulting I/O Allocation size of the Coupler.

  1. In the Multiview Explorer view, right-click the EtherNet/IP Coupler and select Display I/O Allocation from the menu.


  1.  The I/O allocation indicates the input and output data sizes (in bytes) for the present configuration.


The input and output tag sizes are necessary to configure the Ethernet/IP connection in RSLogix.

2.4 [RSLogix] Configure EIP connection

The main view of the RSLogix 5000 software provides the way to add the NX-EIC202 to the PLC’s network. Please see below an example of the main view of the tool.

Perform the following steps to add the NX-EIC202 to the network.

  1. Select the New Module… function of the Ethernet item’s context menu.


  1. Select the NX-EIC202 from the list and click Create.


  1.  Enter the common data such as the Name, Description and IP address in the following form. 


  1. Click on the Change … button to set the detailed IO data.


  1. Please select the correct size of the input and output buffers in the Module Definition window. Use the data as indicated in the I/O Allocation window (see section 2.3). Set the data type to INT and select correct sizes (note Sysmac Studio indicates the size in bytes). Select OK.


  1. The Connection tab of the New Module window gives the settings of RPI and the input type (Unicast/Multicast). Please fill in according to your requirements.


  1. Click  OK to add the NX-EIC202 to the network.


The NX-EIC202 has now been configured. Please follow the standard procedure of the Rockwell software to download configure the PLC and the network.

3. NX-EIC202 Operation

The Controller Tags shows the Input and Output data allocated to the NX-EIC202.

These tags can be used in the PLC program to use the IO data of the coupler.

Appendix A - Setting NTP server connection

The OMRON NX-EIC202 coupler supports the use of an NTP server. Please refer to section 13.3.3 of [1] for details on this feature. Unfortunately the RSLogix does not support to set the NTP settings using the EDS file.
The following two settings are required for the NTP server:

Setting Class (hex) Instance (hex) Attribute (hex) Example value
NT server IP address F5 01 64 ""
Timezone F5 01 66 (GMT + 09:00) Japan

Set the following value for the Timezone setting.

Please note a power cycle is required after changing the settings of these parameters.

Any tool or unit which supports CIP messaging can set the NTP setting based on the description above.

The following section shows how to use the Network Configurator tool to download the settings.

Setting NTP server connection using Network Configurator

Perform the following steps of the Operation Manual to configure the Unit using EDS file (see [1] section 9-5).

  1. Start the Network Configurator
  2. Register the devices that will participate in the tag data links by dragging the devices from the Hardware List and dropping them in the Network Configuration Pane on the right. Please only add the NX-EIC202.
  3. Right-click the registered device’s icon to display the pop-up menu, and select Change Node Address. Set the node address of the NX-EIC202 you want to configure.


  1. Right-click the registered device’s icon to display the pop-up menu, and select Parameter ~ Edit.


  1. Set the two NTP parameters to the required values. Click OK to close the window.


  1. Download the updated settings to the coupler. Right-click the registered device’s icon to display the pop-up menu, and select Parameter ~ Download.
