<p>A system performing an integrated control of a plurality of independent control system. Each of a plurality of control terminals controls the independent control systems. A plurality of interface control devices perform interface control between the independent control system and each of the control terminals. A first switching device switches connections between the control systems and each of the interface control devices. A second switching control device switches connections between each of the interface control devices and each of the control terminals. An external control terminal supplies external instructions to the control device which control the first and second switching devices.</p> |
