    How to use LoadDataValue in C#

    DISCLAIMER

    The example below is intended to demonstrate one or more features or methods and is presented as a configuration example only. Schneider Electric assumes no liability for the use or application of this example or any portion thereof.

    LoadDataValue is a method that can be used to insert historic data to a point (more details on the ClearSCADA Database Schema).
    Below there is an example on how to connect to a local server and use this method:

            private void button9_Click(object sender, EventArgs e)
        {
                DBObject TestPoint;
                Aggregate HistAgg;
     
                Object[] args;
                DateTime dt;
           args = new Object[4];
     
                using (Connection conn = new Connection("TestApp"))
           {
                    // Connect to local server
                    SecureString passwd = new SecureString();
                    string strPassword = "adminexample";
                    foreach (char c in strPassword)
                  passwd.AppendChar(c);
             passwd.MakeReadOnly();
             conn.Connect("localhost");
             conn.LogOn("AdminExample", passwd);
     
                    // Get the point
             TestPoint = conn.GetObject("~Points.A1");
                    // If Historic is enabled for the point, insert historic data
                    if (TestPoint.Aggregates.TryGetValue("Historic", out HistAgg) == true)
             {
                  args[0] = 0;
                  args[1] = 192;
                  dt = new DateTime(2019, 4, 3, 7, 21, 52);
                  args[2] = new System.DateTimeOffset(dt);
                  args[3] = 88;
                  HistAgg.InvokeMethod("LoadDataValue", args);
              }
              conn.LogOff();
              conn.Disconnect();
           }
        }
