Introduction

Each BMENUA0100 Ethernet communication module with embedded OPC UA server that you add to your application instantiates a common collection of data elements. You can use the tools presented in the Control Expert software to access these data elements and diagnose the module.

NOTE:

  • DDT data returned in response to a Modbus request cannot exceed 256 bytes in length.

  • Given the organization of the Control Expert data dictionary, requests for data stored in bits of words need to be extracted by the requesting client.

The contents of the DDT can be accessed using the READ_DDT elementary function (EF) in Control Expert software.

NOTE: .If the module DDT cannot be read for any reason – for example if the backplane IP address is not properly configured – you can perform module diagnostics via the module LEDs.
