Abstract
A communication network suitable for industrial environments includes a set of stations which are linked together by a primary ring which conveys data in one direction around the ring and a secondary ring which conveys data in the other direction. The integrity of both the primary and secondary rings is continuously monitored by each station, and if a problem is detected, the stations automatically switch their mode of operation to bypass the detected problem.
