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 display of the CPU 1511-1 PN or CPU 1513-1 PN. A tooltip appears when
you focus on the respective value on the display and then press the "Left" arrow key. The
tooltip shows the name of the value in complete length.
