Claims (1)

The invention relates to the field of data transmission for information management systems of dispersed objects, for example, an automated process control system. A method of transmitting data over a ring network consists in circulating information-free words containing sync signals and bit intervals, each word being allocated one message bit for each subscriber subsystem that simultaneously reads the bit interval and changes the signal value without affecting the adjacent intervals, and automatically controlled delay is introduced into the signal path; subsystems requiring high speeds are assigned several bit intervals in a word so that the time intervals between the selected bits are constant under the condition of the continuity of the words along the ring provided by the above-mentioned controlled delay. The data transmission device, which has the brand name GROWTH-RING, implements the method described above, thereby achieving the ability of the device to transmit digital information via different communication systems of an automated process control system simultaneously over the same communication line without simultaneous delays at intermediate ring stations.
