Start OPC Data Acquistionin Genesis 3.1

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 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 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 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:



Click on the different elements (draw in blue) below to view localization of OPC Acquisition Information.

• OPC Server Attributes: Server Id, OPC Server Host, Connection Status and Server Status
• OPC Data Acquisition:
  1. Acquisition Status: the actual text depend on the acquisition mode
  2. Project Id: this is the identifier of the current OPC Data acquisition session in the Genesis Database
  3. Number of Acquired Data
  4. Data Acquisition Times: First, Last and Next Data Acquisition time
• OPC Real-Time Data: Listing of Last Acquired Data with Id, Short Id, Description, Acquisition Time, OPC Value and OPC Quality
• OPC Performance Data (all times expressed in milliseconds)
  1. Data Acquisition: Statistics of Data acquisition (last, average, minimum and maximum time for OPC Data acquisition)
  2. Database Update: Statistics of data storage in Genesis database (last, average, minimum and maximum time for OPC Data storage)
  3. Performance Chart; Chart of Last Time for Data Acquisition (Red Trends) and Data Storage (Blue Trends)

Note that the Performance Data controls can be either displayed or hidden using the menu associated with the button'Performance Data Display'
