Controls Interface
Event Enable/Disable Screen
Event Active Days Screen
This screen is unusual because it does not use radio
buttons, which only allow one active selection at a time.
These buttons are more like "selection buttons" or check
boxes.The user can select any combination of days, or
none at all.
Event Time Screen
Event Arbitrated Settings Screens
For analog setpoints, the screen is slightly different than
the standard screen, because there are two additional
buttons - "Used" and "Not Used" . Selecting "Used" will
make the setting valid and allow the user to change the
value. Selecting "Not Used" will make the setting invalid,
and will not allow the user to change the value.
