NJ and NX Series Controllers

Maple Systems' NJ and NX series connection guide has everything you need to connect your Omron NJ or NX series PLC with Maple Systems' graphical HMIs. It includes all you need to begin communicating between devices via EtherNet/IP.

Omron's Sysmac platform PLCs

Integrating Omron’s NJ or NX series of PLCs into your existing network is simple thanks to Maple Systems’ near-universal HMI compatibility. Connecting to an NJ or NX series device is done via EtherNet/IP for easy connection between our graphical HMIs and an Omron PLC. Unlike CJ/CP/CS platforms, NJ/NX controllers do not support HostLink or FINS-based communication.

Quick Start Guides

Our quick start guides help you get your Maple Systems HMI and Omron PLCs communicating in a few simple steps.

EtherNet/IP

This guide walks you through connecting an Omron NJ or NX Series PLC to EBPro using EtherNet/IP, downloading tags from the controller, and using those tags in your HMI project. Each step is designed to help you establish communication and start building screens, even if you’re new to EtherNet/IP or EBPro.

Instructions: EtherNet/IP

  1. Connect the PLC and Your PC Using Ethernet

    Using a standard Ethernet cable, connect the Omron PLC and a PC that is running the EBPro application. Make sure the PC and PLC’s IP addresses are on the same subnet, or they will not be able to communicate directly.

  2. Add the Omron NJ/NX EtherNet/IP Device

    Add a new Device/Server in the System Parameter Settings and select Omron Ethernet/IP (NJ/NX Series) as the device.

  3. Enter the PLC IP Address

    Open the Device Settings and enter the IP address for your Omron PLC.

  4. Download Tags from the PLC

    Save the settings in the Device Properties. Select the device on the Device List in the System Parameters Settings. Click Get Tag Info. You will see a prompt to select the IEC-61131 STRING type. Select either one CHAR per word, or two CHARs per word. Note that this must match the settings on the PLC, or string values may display incorrectly.

    The HMI will now automatically contact the controller and download any loaded tags for use immediately in the HMI project.

  5. Use PLC Tags in Your HMI Objects

    You can now configure any of the objects available in EBPro by simply placing the object, selecting your Omron controller as the device and browsing to the tag you want to use.

Once you are ready, you can run the project in one of EBPro’s simulation modes or download it to an HMI for testing. To learn more about HMI project simulation, check out our Try Before You Buy page.

Demo Project

To see a prebuilt project for an NJ or NX series PLC, check out our NX102-9000 Pump Demo Project for EBPro. This demo comes preconfigured to communicate with an NX102 PLC using the EtherNet/IP protocol. Play the video below to see a preview of this demo project in action, then follow the instructions to install and run the project on your development PC.

Follow the steps below to open this demo project in EBPro:

  1. Download the compressed NX102-9000 Pump Demo Project folder.
  2. Extract the files from the zipped folder and save them to a local drive on your PC.
  3. Open the EBPro configuration software.
  4. Open the File menu and select Compress/Uncompress.
  5. In the Uncompress section of the window, click Browse, then select the Omron_NX102-9000_Pump_Demo.ccmp file that was just extracted from the zipped folder in step 2. Click Uncompress.
  6. The uncompressed project file will now be saved in the same location as the .ccmp file with a *.cmtp file extension.
  7. Use File > Open in EBPro to open the uncompressed project file.
