PURPOSE: A supervisory control system is provided to control effectively a driving state of a field device by installing a supervisory control system easily attachable and detachable. CONSTITUTION: A plurality of signal sensing modules(120) are connected to a power line of a terminal without contacting. A magnetic field by the current flow of the power line is sensed. A relay control module(140) generates the state data corresponding to an inputted electric signal. The generates status information is outputted to an integrated control module(150). The integration control module stores the identification code and the status information.
