This paper presents a fault-tolerant distributed system designed for real-time control applications (REBUS), which is one of the research basis of the industrial real-time system MODUMAT 800. It is made up of functional units, i.e., programmable multiloop regulators and operator displays, linked together by a communication structure. The communication hardware consists of a set of serial bus interface boards, one per functional unit, loosely coupled together by a double serial bus and linked to their functional units by a private parallel bus.
