Screen partitioning on the OP (example OP37)
The fixed window can be used to display important process magnitudes or date
and time, since the contents are not affected by the screen currently open.
The main area comprises the entire display. It is superimposed by all other
areas (fixed window, message window etc.). The main area contains the current
contents of the screen that is currently open.
Icons are used as symbols of specific screen functions. Icons are located above
or next to soft key function keys in order to describe the functionality of the
key. The configured function is triggered after pressing the function key.
