2-4 Microview Overview

Function Key Operations

Function keys can be linked to application screens allowing quick
access to critical data display or data entry screens. For example, if
the F1 function key is linked to Recipe Screen 10, the operator can
press F1 at any point in the application to download recipe registers
on screen 10 to the processor. A control mode can be assigned to
each function key linked to a screen.

Sends data to the controller. Data can either be default values
or data entered at the keyboard.

Enters numbers 0 to 9 during data entry or selects a numbered
item shown on the display.

Displays any application screen assigned to the key. These
keys can also set or clear bits at two consecutive registers in
the controller data table.
