Connection Parameters Needed for HMI/cMT Products to Communicate with an Allen-Bradley EtherNet/IP ControlLogix Free Tag Names using EBPro (EasyBuilder Pro)

Introduction

All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with a Rockwell/Allen-Bradley EtherNet/IP ControlLogix Free Tag Names. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.

Supported Series: Rockwell ControlLogix, CompactLogix, FelxLogix Ethernet, CompactLogix 1768-L43 1768-L45 with 1768-ENBT/A Ethernet module

PLC Settings

  1. Set PLC IP Address

    In RSLogix5000 / Studio 5000, open Controller Properties and go to the Internet Protocol tab. Set the IP address, subnet mask, and gateway for the controller’s Ethernet port.
    Controller Properties dialog in RSLogix 5000 showing the Internet Protocol tab with IP Address set to 192.168.1.100 and Subnet Mask 255.255.255.0.

  2. Create New Controller Tags

    Create new tags in RSLogix5000 / Studio5000 (Controller Tags and Program Tags are both supported). Both the Controller Tags editor and the Program Parameters and Local Tags panel are available for defining tags.

Tag Import Methods

There are two ways to get tags: import .L5X or .CSV files (click Import Tags…), or connect to the PLC directly (click Get Tag Info…). After creating a project using one of these methods, use the same method for future maintenance to prevent compilation failure.

  • Recommended for PLC Offline: Import .L5X
  • Recommended for PLC Online: Get Tag Info

NOTE: Description is only supported for atomic tags. Not supported for structure or array tags.

Get Tag Info

  1. Verify Communication Parameters

    After adding the driver in EBPro (EasyBuilder Pro), confirm that all communication parameters are correct, then click Get Tag Info.

  2. Select Tags to Import

    In the Tag Manager dialog, select the tag information to be imported, then click OK.

  3. Confirm Import Success

    Click OK after the tag information is imported successfully.
    EasyBuilder Pro confirmation dialog displaying Imported tag information successfully with an OK button.

  4. Review Imported Tags

    View the imported tag information in the list, then click the close icon X to exit.
    EasyBuilder Pro imported tags list showing tag names including F1, F2, Local:1:C, P1, P2, Prefefined_Alarm, TagBool, TagDINT, and Program:MainProgram with their data types.

Import Tag (L5X)

  1. Export L5X File from RSLogix

    Export the .L5X file from RSLogix5000 software. Navigate to *File u0026gt; Save As u0026gt; .L5X**.

  2. Select L5X Importer in EBPro (EasyBuilder Pro)

    Add the driver in EBPro (EasyBuilder Pro), click Import Tags, select *Import Files (.L5X), and click OK**.
    Import Tags dialog in EasyBuilder Pro with Import Files (*.L5X) Hierarchical selected from the importer type list.

  3. Review Imported Tag Information

    View the imported tag information in the Tag Manager, then click the close icon X to exit.
    Tag Manager dialog in EasyBuilder Pro showing Device_tags and Program:MainProgram tag hierarchy with Arr_2D_DNT selected and Member Data showing DINT type.

  4. Confirm Tag Import Success

    Click OK after the tag information is imported successfully.

Import Tag (CSV)

Tags edited in RSLogix5000 can be exported as a CSV file and then imported into EBPro (EasyBuilder Pro).

  1. Export Tags to CSV from RSLogix

    Export tag data to a CSV file using Tools u0026gt; Export u0026gt; Tags and Logic Comments.
    The separator character in the CSV file must be a comma , — otherwise the file is invalid. To change the separator, go to Control Panel u0026gt; Date, Time, Language, and Regional Options u0026gt; Change the format of numbers, dates, and times u0026gt; Customize u0026gt; List separator. Select , and then export the CSV file.
    RSLogix 5000 Tools menu open showing Export submenu with Tags and Logic Comments highlighted.

  2. Import CSV File in EBPro (EasyBuilder Pro)

    In System Parameter Settings, click Import Tags, select *Import Files (.CSV), and click OK**.
    Import Tags dialog in EasyBuilder Pro with Import Files (*.CSV) Linear selected from the importer type list.

  3. Choose Data Type Handling

    Decide whether to keep the current data type (User-Defined, Strings, Predefined, Module-Defined) or replace with the default data type.
    EasyBuilder Pro dialog asking whether to keep the current data type (User-Defined, Strings, Predefined, Module-Defined) with Yes and No buttons.

  4. Review Unsupported Tag Warnings

    A Warning window appears when unsupported tags are encountered. Check whether these tags use unrecognized data types and add the necessary ones using Data Type….
    EasyBuilder Pro Warning dialog listing tags with unknown data types such as Fluid, Pump, and AB:5000_DI16 with instructions to define structures or skip unsupported tags.

  5. Select String Import Mode

    When importing STRING tags, a dialog prompts you to choose between one char per word or two chars per word. Select the appropriate mode for your project and click OK.
    IEC-61131 STRING type select dialog in EasyBuilder Pro showing One char per word vs Two char per word options with byte and word index mapping examples.

NOTE:

  1. EBPro V6.03.02 or later supports 64-bit data types (cMT Series only). The address limit range is 48 bits maximum.
  2. Avoid using . in tag names as this may influence macro execution.
  3. Shorter tag names are recommended for enhancing communication efficiency.
  4. When importing, choose between one char per word or two chars per word. For one char per word, choose Unicode data format for ASCII objects; for two chars per word, choose UTF-8 (Default) data format.
  5. Data format supported for Binary Access: INT, DINT, and SINT.

Wiring Diagram

NOTE: Connect the HMI to the PLC using a standard Ethernet cable (Cat5e or higher, straight-through wiring).

The diagram below shows the Ethernet cable wiring.
