3. If the Enter Handshake tag is assigned, the Enter tag remains set until the Enter key
handshake time expires or until it is reset by the Enter Handshake control, whichever
happens first.
If the Enter Handshake tag is not assigned, the Enter tag remains set until the Enter
key hold time expires.
4. The Enter tag is reset to 0.
How the Handshake reset type option works
The Enter Handshake tag resets the Enter tag as follows:
 Non-zero value resets the Enter tag when the Enter Handshake tag is a non-zero
value.
 Zero to non-zero transition resets the Enter tag when the Enter Handshake tag
changes from zero to a non-zero value.
Before the Enter tag is reset to 0, the operator can provide input to other objects in the
graphic display.
If the operator presses the Enter key for an object whose Enter tag has not yet been reset
(using a key, or external keyboard or keypad), an error is logged to the Diagnostics log.
If the graphic display is closed, the Enter tag is reset to 0, and any handshake timing is
also reset.
Creating piloted control selectors
Use the Piloted Control List Selector tool to create a list that displays multiple options,
and lets an operator cycle through the options consecutively. The piloted control list
selector displays the current state of a process or operation by highlighting the state.
A piloted control list selector can be operator controlled, remote controlled, operator and
remote controlled, or neither.
Specifying the text and value for each state
Piloted control list selectors change their appearance and the Value tag, based on their
states.
In the States tab of the Properties dialog box, for each state, you specify the text that
appears in the list and the value for the Value tag.
You can also set up whether each state can be operator controlled, remote controlled,
operator and remote controlled, or neither. If None is selected, the state is turned off and
cannot be selected.
