<p>PROBLEM TO BE SOLVED: To provide a remote monitoring control system capable of operating stepped dimming and continuous dimming using a single terminal unit. SOLUTION: A terminal unit 35 for dimming operation of this remote supervisory control system is equipped with a dimming data memory part 13 for storing dimming data. Furthermore the terminal unit 35 is equipped with an up-switch Su for instructing increase in the optical-output from an illuminating load in the operation mode, a down-switch Sd to instruct a decrease in the optical- output from the illuminating load in the operation mode, and a select switch Sf to circularly select the dimming data at each run of operation in the operation mode and give it to the terminal unit. Thus continuous dimming is made possible with the up-switch Su and down-switch Sd, and stepped dimming becomes possible with the select switch Sf.</p> |
