       Genesis OPC Acquisition Data Matrix

Acqusition Data Matrix is a graphical presentation of the acquisition schedule used internally by Genesis OPC Explorer 3.1 to handle the OPC data acquisition when OPC Groups have different acquisition rate.

There are two methods to view the Data Acquisition Matrix via buttons of the Ribbon Category 'Data Acquisition'



  • Direct Way
    • Click on the Button 'Acquisition Data Matrix' of the Ribbon Category 'Data Acquisition'

  • Indirect Way
    • Click on the Button 'Start Data Acquisition' of the Ribbon Category 'Data Acquisition'

    • Click on the button 'View Acq. Matrix'

      View Acquisition Matrix


  • Simple Acquisition Matrix

    Suppose a simple Genesis Project with three OPC Groups with different acquisition rate: 100 ms, 500 ms and 1 second

    View Acquisition Matrix


    Genesis OPC Explorer 3.1 computes the smallest acquisition rate to allow consistent acquisition and then optimize the OPC acquisition.

    Simple Acquisition Matrix


    The green cells represent the OPC Groups for which data acquisition is triggered at every periodic acquisition request.

  • Less Simple Acquisition Matrix

    Suppose a less simple Genesis Project with four OPC Groups with different acquisition rate: 100 ms, 500 ms, 3 seconds and 1 second

    View Acquisition Matrix


    Genesis OPC Explorer 3.1 computes the smallest acquisition rate to allow consistent acquisition and then optimize the OPC acquisition.

    Less Simple Acquisition Matrix


    The green cells represent the OPC Groups for which data acquisition is triggered at every periodic acquisition request.

    The complete picture is a little bit harder to handle

    Less Simple Complete Acquisition Matrix


The size of the matrix is limited to 256 entries. Some extreme combinations of OPC Groups with very fast and very slow acquisition rates generate an invalid Data Acquisition Matrix that exceeds the maxium Matrix size.

If such event arises, Genesis OPC Explorer 3.1 triggers a Message Box to warn for invalid OPC Server setup
