Connection Parameters Needed for HMI/cMT Products to Communicate with ODVA EtherNet/IP Extension (Explicit Messaging) 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 ODVA EtherNet/IP Extension (Explicit Messaging). Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.

Supported Series: Crevis EtherNet/IP NA-9188

Tag Manager

  1. Open Tag Manager and Browse

    Click the Tag Manager button, then click the Browse button. The found objects will be displayed on the list.
    EthernetIp Setting dialog showing the Tag Item tree with Assembly_Object#4, Ethernet_Link_Object#246, Identity#1, and TCP_IP_Object#245, with the Browse button highlighted.

  2. Browse Assembly Object Instances

    Expand Assembly_Object#4 in the Tag Item tree to view its instances and attributes. Use Add Instance to add new instances as needed.
    EthernetIp Setting dialog with Assembly_Object#4 expanded showing instance#0 with attribute#3 set to BYTE[2], and the Add Instance button visible alongside Item/Value panel.

  3. Edit Address Tag

    To edit an address tag, refer to the factory manual. The following is an example of how to add Vendor ID in Tag Editor. See 3.2.3 Identity Object in the factory manual for details on this ID.nnUnder Struct-Defined, select Identity to add Vendor_ID. {1,1,1} represents {Class code, Instance ID, Attribute ID}. Enter UINT in the Data Type field according to the factory manual. When finished, this data member can be found in Identity Object.
    EthernetIp Setting dialog with Identity#1 expanded showing Instance#1 attributes (Attribute#1 through Attribute#7) with BYTE data types, and the Item/Value panel showing raw_data byte_array with values 60 and 6.
    Crevis factory manual excerpt showing Identity Object class code 01HEX and Instance Attributes table with columns for Instance ID, Attribute ID, Access Rule, Name, Data Type, and Value — including Vendor ID (741, Crevis Co. Ltd), Device Type, Product Code (512, NA-9188), and Revision.

Limitations

  1. If offset is set for a user-defined tag, data cannot be written.
  2. If the user-defined tag length is inconsistent with the server, data cannot be written.
  3. [Binary Access] Not suitable for fast writing in HMI — for example: momentary objects, which will conflict with PLC control and cause abnormal reading and writing status.
