P271 – Digital Input Signal
Adjustable 0 = All DIx are NPN
Range: 1 = Reserved
2 = (DI5...DI8) - PNP
3 = Reserved
Properties:
cfg
Description:
It configures the default for the digital input signal, that is, NPN and the digital input is activated with 0 V, PNP
and the digital input is activated with +24 V.
a) RUN/STOP
