nn
Parameterisation active; additional information shows current
parameter nn in the form PNU/100 (PNU 400 becomes 04).
If a parameter is changed acycliclly or in the parameterisation
operating mode, the corresponding PNU is displayed as PNU/100
for the duration of 1 second. No display appears during read para
meter access or a parameter access over the diagnostic interface
(FCT CMAX plug-in).
If a new write parameter access is made within this display time
window, the new PNU is displayed as PNU/100 and the display
time begins again (1 second).
If in the parameterisation operating mode, no parameter has
been changed yet or the display time has expired, the additional
