Fixed window
The fixed window is an area at the top of the screen. The height of the fixed
window can be configured. Since the content of the fixed window is independent of
the screen currently displayed, it is especially suited for displaying important
process magnitudes or date and time.
Basic area
The basic area covers the entire screen. It is superimposed by all other areas
(fixed window, message window, help window, etc.). The basic area contains the
real content of the screen currently open.
Icons
Icons are graphics of a fixed size located at the bottom and sides of the screen.
They are defined during configuration and clearly indicate the functions of the
softkeys in graphic form.
After pressing the respective softkey, F1 to F20, the function symbolized by the
icon is activated either on the MP270 or in the PLC.
Message indicator
The message indicator is a graphical symbol which appears on the
screen when at least one alarm message is present on the MP270.
The indicator continues to blink as long as unacknowledged messages
are present.
The number (in this case 3) represents the number of alarm messages
present.
The message indicator is always displayed in the foreground.
