ARRANGEMENT FOR COUPLING DIGITAL PROCESSING UNITS

摘要

A data bus system in which digital processing modules are associated with the busses in matrix fashion is disclosed. The modules contain respective intelligent and autonomously operating coupling units, by which information distribution on the busses, fault detection and error processing may be transacted in a decentralized manner. The system is highly secure and fault-tolerant. A corresponding matrix bus system together with the corresponding current couplers can also connect power supplies associated with each of the modules to each other in the event of failure of the power supply in an individual module.
