Create the AlarmImporter NetLogic

Develop a NetLogic that imports alarm data.
Set the default external code editor. See Set the default code editor.
  1. To develop the NetLogic
  2. In
    Project view
    , right-click
    and select
    Design-time NetLogic
  3. Hover-over the NetLogic, select
    , and enter
  4. Double-click the NetLogic.
    The external code editor opens.
  5. In the code editor, replace the existing code with the following code:
    #region Using directives using UAManagedCore; using OpcUa = UAManagedCore.OpcUa; using FTOptix.HMIProject; using FTOptix.Core; using FTOptix.Alarm; using FTOptix.NetLogic; #endregion public class AlarmImporter : BaseNetLogic { [ExportMethod] public void ImportAlarms() { // Reads the CSVPath property of the NetLogic. It is configured with datatype Absolute resource URI string csvPathVariable = LogicObject.GetVariable("CSVPath").Value; var csvPath = new ResourceUri(csvPathVariable).Uri; var modelFolder = Project.Current.Get("Model"); var alarmsFolder = Project.Current.Get("Alarms"); if (csvPath.Length == 0 || !System.IO.File.Exists(csvPath)) { Log.Error("CSV not found. Please configure the CSV to parse in the NetLogic configuration"); return; } // Clear the content of Model and Alarms folders, just for the sake of the example. It let you re-run the command // without adding the same alarm or variable again. modelFolder.Children.Clear(); alarmsFolder.Children.Clear(); string[] lines = System.IO.File.ReadAllLines(csvPath); foreach (string line in lines) { var tokens = line.Split(','); if (tokens[0] == "variable") { NodeId dataType = tokens[2] == "boolean" ? OpcUa.DataTypes.Boolean : OpcUa.DataTypes.UInt32; var newVariable = InformationModel.MakeVariable(tokens[1], dataType); modelFolder.Add(newVariable); } else if (tokens[0] == "alarm") { // Searches the variable to link before creating the alarm var inputVariable = modelFolder.GetVariable(tokens[3]); AlarmController newAlarm; if (tokens[2] == "digital") newAlarm = InformationModel.MakeObject<DigitalAlarm>(tokens[1]); else newAlarm = InformationModel.MakeObject<ExclusiveLevelAlarmController>(tokens[1]); // Creates a dynamic link from the InputValue property of the Alarm to the actual variable newAlarm.InputValueVariable.SetDynamicLink(inputVariable); alarmsFolder.Add(newAlarm); } } } }
  6. Save the code.
