Zusammenfassung:	A computer controls a plurality of satellite machines in real time via a single bus comprised of undedicated, continuous transmission lines terminated at both ends in matching impedances. Each machine coupled to the bus is addressed and commanded during every computer cycle, responding only to signals directed to its address. When a machine is not electrically powered the computer provides an internal signal; computer cycles are never interrupted; continuous control of all other machines is maintained. Any number and mixed types of machines may operate from the bus simultaneously. Machines may be added or removed from bus, and machine programs may be added, removed or modified without interrupting operation of the other machines. Automatic safety reset is provided for machine or computer failure.
