Abstract

En rekke stasjoner (S), eksempelvis måleprober, gjerne omfattende hver sin mikroprosessor (KL), koples suksessivt til en felles toleder-linje (SL). Gjennom denne linjen (SL) distribueres matespenninger og synkroniseringssignal fra en sentralenhet (CU), samtidig som en full dupleks-kommunikasjon mellom enkelt-stasjon (S) og sentralenheten (CU) muliggjøres.
