Screen selectors provide a way for an operator to move to another screen,
or to return to a previously displayed screen. Normally, every screen
should have a screen selector, so that an operator is not stranded at a
particular screen.

All screens can be coded for security. If the wrong code is entered an error
message is displayed and the screen does not change.

If the requested screen does not exist, or is corrupted, an error is displayed
and the screen does not change.

IMPORTANT: If the PLC Controlled Screen Change is enabled and the
value at the associated PLC address is not zero, the PLC controller, not the
operator, has control over screen changes. If the operator presses a screen
selector, an error message appears.

Screen selection by the operator is not allowed when “Minimum Push
Button On Time”, “Latch Button PLC Handshakes” or “Enter Bit
Handshakes” are outstanding. An error message will be displayed and the
screen will not change.

Go To Screen" Button

The “Go To Screen” button is used to display another screen. Once you
have added the object to your screen, choose Screen from the menu. In the
window that opens, type the number of the screen you want to go to when
the button is pressed. Then choose Quit to return to the Object menu and
your screen.

For example, a button labeled “View Current Status” could be included on
a screen. The button could be configured to go to a screen displaying the
current status. That screen would include a “Return To Previous Screen”
button, so the operator could easily return.

Another example: a button labeled “Select New Screen” could be
configured to go to a screen displaying a keypad screen selector (for Touch
Screen terminals) or a keypad screen select button (for Keypad terminals).
The operator could then select the desired screen by entering the screen
number.

Return To Previous Screen" Button

The “Return To Previous Screen” button returns to the screen previously
displayed.
