CPU display
Tooltips
Some of the values shown on the display (e.g., station name, plant designation, location
identifier, PROFINET device name, etc.) can exceed the available display width. This applies
in particular to the CPUs with a small display. If you focus on the relevant value on the
display and then press the "Left" arrow key, a tooltip appears. The tooltip shows the name of
the value in complete length. The tooltip is hidden again if you again press the "Left" arrow or
the ESC key.
