You can set up the piloted control list selector to be operator-controlled or remote-
controlled by assigning tags or expressions in the Connections tab.
You can also set up individual states to be operator-controlled, remote-controlled, both, or
none. If set to none, the state is turned off.
If the piloted control list selector is set up to be operator-controlled, and the operator
selects a remote-controlled state, or one that is turned off, a hollow cursor is shown.
Use buttons with the piloted control list selector
When a piloted control list selector is operator-controlled, it works with:
 Key button graphic objects. These are graphic objects that duplicate the functions of
keyboard keys.
 The arrow keys and Enter key on a terminal’s keypad.
 The arrow keys and Enter key on a keyboard.
The operator presses the buttons to scroll up or down the list, or to make selections from
the list. The buttons can be set up to work with the piloted control list selector that has
focus, or with a specific piloted control list selector. You can use the buttons listed in the
table on page 21-49.
Select items in the list
Each state can be selected directly by an operator, or remotely by a device such as a
programmable controller. The operator or the controller scrolls through the list to select a
different state or a different group of visible states.
When an operator or remote device selects a state, the value assigned to the selected state
is written to the piloted control list selector’s Value connection. If the state is turned off,
the state’s value is not written to the Value connection.
If the operator attempts to select a state that is remote-controlled, the state’s value is not
written to the Value connection.
The operator can select this state. The operator cannot select this
state.
