Use the
Connections
 tab of the
Control List Selector Properties
 dialog box to set up tags and expressions for the object.
To set up tags and expressions for a control list selector
  1. In the
    Graphics Display
     editor, double-click the selector to open its
    Properties
    dialog box.
  2. Click the
    Connections
     tab.
  3. Assign a tag or expression to these connections:
    Value
    Assign a tag to this connection. When the operator selects a state, the application writes the value corresponding to the selected state to the tag’s data source. The application also monitors this connection and if the value changes, highlights the new state in the list.
    The Value connection triggers the state's action. For example, when the tag assigned to the connection changes to a new state, the data source changes a motor's speed to a new setting.
    TIP:
    If
    Write on enter
     is selected on the
    General
    tab, the application does not write to the Value connection until the operator selects a state and presses
    Enter.
    If
    Write on enter
     is not selected on the
    General
     tab, the application writes to the Value connection as soon as a state is selected. The Enter and Enter Handshake connections are ignored.
    Enter
    This connection accepts values of 0 and 1 only. The connection determines how long the
    Enter
     key press is registered. Use this connection for Enter key handshaking.
    Enter Handshake
    You can assign a tag or an expression to this connection. This connection resets the Enter connection, using the Handshake reset type property specified on the
    Timing
    tab. Use this connection for Enter key handshaking if you want the Enter connection to be reset when a value at the data source changes.
    If you assign an expression, the application calculates the value of the expression and resets the Enter connection when the expression value meets the conditions of the Handshake reset type option.
