ABSTRACT:
A method for data transmission in a hierarchically organized data transmission network wherein a central arithmetic unit cyclicly enables local concentrators to transmit data which the concentrators receive from a number of terminals undertakes a check at every concentrator by means of a change detector to determine whether incoming data has changed in comparison to a preceeding inquiry. When a change has occurred, all relative data are immediately transmitted to the arithmetic unit, otherwise, a short acknowledge character is transmitted. A time-redundant inquiry/acknowledge procedure is thus avoided.
