Function Keys
An application designer can link function keys [F1] through [F8] to
individual screens (except alarm screens). Pressing an assigned function key
displays the function key number for approximately 0.5 seconds and then the
assigned screen. It is the responsibility of the application designer to
document the operations assigned to function keys. There are two function
key modes:
•
Auto Return
•
Continue
Auto Return
Auto return function keys return to the initial display after the linked screen
is executed. For example, assume that an application is displaying screen #6
and an auto return function key [F3] is linked to a recipe screen #10. When
[F3] is pressed, the recipe screen #10 is displayed. After the operator
downloads a new recipe on screen #10, the initial screen #6 is displayed.
The following table describes when the return to the initial screen occurs.
Function Key Linked To:
Data Display Screen
Data Entry Screen
Recipe Screen
[NEXT] or [PREV] keys abort the operation.
Continue
Continue function keys do not return to the initial display but remain at the
linked screen. For example, assume that an application is displaying screen
#3 and a "continue" function key [F2] is linked to a data entry screen #5.
When [F2] is pressed, the data entry screen #5 is displayed. The application
continues from screen #5.
