When the supervisory personnel resident apart from the central supervisory room desires to recognize the state of the process 10 from its own resident location, the personnel connects a MODEM 50 of a portable central supervisory equipment 70 to a public line 60 to access the central supervisory equipment 20, then process state information is sent to the portable supervisory equipment 70 through the public line 60 from a data transmission section 23 provided to the central supervisory equipment 20 and displayed on a display means. When the operation of the process 10 is required, the supervisory personnel receives a required command from the input means of the portable supervisory equipment 70 to take required action for the restoration of the process 10.</p> |
