This article describes a system arrangement which automatically circumvents and isolates single point faults without action by a controller. The low cost and programmability of microprocessor-based hardware has made multi-unit federated systems feasible and attractive. Such systems, for example, are used extensively in high volume production automobiles to interconnect units for engine control, body control, display, temperature, entertainment and other functions. In such applications, serviceability and availability are very important and it is consequently desirable to detect and isolate electronic component faults quickly while maintaining a functioning system.
