      Start Genesis OPC Data Acquistion

Once a Genesis OPC Project is either setup (see here for details) or loaded ( see here for details), the Data Acquisition can be started.
  • Click on the icon 'Data Acquisition and Storage' in the left pane of Genesis OPC Explorer 3.1 main window.

    Note that the icons 'OPC Data Listing' and 'OPC Data Charting' are still grayed as no OPC data is available.

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

At that point, Genesis OPC Explorer 3.1 can handle Data Acquisition in two different modes:
  • Continuous Data Acquisition

    In that mode, data acquistion is started directly and will run continuously. Once the session is finished, the data acquisition have to be stopped manually.

    Selection of Continuous Data Acquisition Control

  • Time-Controlled Data Acquisition

    In that mode, the start time and end time of data acquisiton can be selected before the start of acquisition. Genesis OPC Explorer 3.1 will start data acquisition at requested start time and will automatically stop at the requested end time.

    Selection of Time-Controlled Data Acquisition Control

    Depending on the size of the Acquisition Data Matrix, the actual end time of data acquisition might be delayed after the requested end time of data acquisition. More about Data Acquisition Matrix here
The view 'Data Acquisition and Storage' gives a lot of information about the running processes of OPC Data Acquisition:
