To set up tags and expressions for a list indicator
  1. In the
    Graphics Display
     editor, double-click the indicator to open its
    Properties
     dialog box.
  2. Click the
    Connections
    tab.
  3. Assign a tag or expression to this connection:
    Indicator
    A read connection. You can assign a tag or an expression to this connection. If you assign this connection, the object does not display the value sent to the Value connection until it receives a response from the Indicator connection.
    If you assign a tag, the application reads the value of the tag at the data source, assigns this value to the connection, and updates the object in the display to reflect the state corresponding to the value or least significant bit value (depending on the trigger type).
    If you assign an expression, the application calculates the value of the expression and updates the object’s display to reflect the state corresponding to the value or least significant bit value (depending on the trigger type).
