3.6 Start-up behaviour of the CPX terminal
If the M-LED lights up permanently after the system start,
the parameter "System start with saved parametrizing and
saved CPX equipment status" is set.
Caution
In the case of CPX terminals on which the M-LED lights
up permanently, parametrizing will not be carried out
automatically by the higher-order system if the CPX
terminal has been replaced after servicing. In these
cases check before replacing to see which settings are
required and carry out these settings.
Detailed instructions can be found in the manual for the
field bus node P.BE-CPX-FB11-... or in the manual for your
handheld.
