Create a piloted control list selector

Use the piloted control list selector to select from a list of states for a process or operation. The selected state on the list is highlighted. If the list scrolls, the state at the top of the list is highlighted.

The object can be controlled 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. The object can be configured to write out the value of the selected state, the value of the state in the top position on the list, and the values of all the states visible on the list, to the data source. If all the visible states of the object are being written, the data source must be a direct reference array tag with a length that matches the number of states visible on the list. The syntax of such an array tag depends on the

When the piloted control list object is selected, if the object is operator-controlled, the operator can scroll through the list and select states using key buttons or by using the arrow keys and Enter key on a keypad or an external keyboard. Key buttons can also be linked directly to the piloted control list selector so that they will work whether the object has the input focus or not.
