Abstract

An automation system has a plurality of subscribers including a first primary unit, first distributor, second primary unit, second distributor, and at least another subscriber unit. First and second transmitting/receiving devices of the first and second distributor are connected via a ring-shaped data bus. In a first mode, the first distributor forwards telegrams received from the first primary unit to the first transmitting/receiving device, and forwards telegrams received by the second transmitting/receiving device to the first primary unit. The second distributor also forwards first telegrams received by the first transmitting/receiving device to the second transmitting/receiving device. In a second mode, the second distributor forwards telegrams received by the second primary unit to the second transmitting/receiving device, and the second distributor forwards telegrams received by the first transmitting/receiving device to the second primary unit. The first distributor also forwards telegrams received by the second transmitting/receiving device to the first transmitting/receiving device.
