Abstract
A decentralized processing system having a plurality of subsystems of the same type which are connected to one another. Each subsystem has a diagnosis means for diagnosis of failure in other subsystems, and functions to take a suitable countermeasure in response to the result of the diagnosis. When a failure has occurred in any one of the subsystems constituting the processing system, each subsystem can conduct a suitable fault time processing in accordance with the state of the failure. After the recovery from the failure, each system can execute a processing for recovering the ordinary status. The subsystems can correspond with each other to conduct the processings in synchronization as required. It is, therefore, possible to attain synchronous operation of two or more subsystems in various control systems or the like.
