REX640 Engineering Manual
  1. In SLD Editor, prepare the body of the single-line diagram by placing symbols to the wanted positions on the page view.
  2. Drag the apparatus or transformer symbols to the SLD Editor view.
  3. Drag the connection symbols.
  4. Place the junction points.
  5. Connect the symbols where necessary by drawing lines between the symbols' source and destination ports.

  6. In the Object Properties pane, set the symbol properties.
    • Use the x and y coordinates to adjust the placement of symbols in the single-line diagram.
    • Use controlState to define the default state of the symbol to be displayed in the view.
    • Use indicationOnly to define if the symbol is controllable (true = status only; false = controllable).
    • Use control to link the symbol to the function block in the application configuration that protects or controls the object.
    • Use stateColorMap to specify colors for the different states of the symbol.

If custom symbols have been used in the SLD configuration and then deleted, the symbol graphics show an error and all the related connections are removed from the configuration.
