    Indicator
    A read connection. You can assign a tag or an expression to this 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).
