A control system includes a first network including a controller 1, a second network including one or more controlled devices 3 to 6, and a translator 2 correlated with the first network and with the second network. The controlled device 3 comprises a controlled device information management unit 23 which manages controlled device information related to the controlled device 3; and a controlled device information communication unit 24 which sends controlled device information with appropriate timing. The translator 3 comprises a controlled device information proxy creating means which creates controlled device information proxies 35 based on controlled device information acquired from controlled devices 3; and an information managing means for registering and managing controlled device information and controlled device information proxies 35. The controller 1 comprises a means which acquires controlled device information proxies 35 from the translator 2 and issues operating instructions for operating the controlled devices 3 to 6. With this control system, an operator at a remote operation center can easily and remotely control equipment belonging to a network different from a network to which the remote operation center belongs.
