PURPOSE:To provide an operator with high-speed system indication by a method wherein terminal point data in a display area is transmitted and the transmitted data is limited to the minimized data to contrive the shortening of a transmitting time upon transmitting display data from a main computer to a system display computer, outputting to and display data on a system supervisory board. CONSTITUTION:Terminal point data is obtained considering that there is no conditional variation in CB, circumscribed (outside of display area) to the terminal point data. As the result of this process, the terminal point data CB14, 15, 24, 25 are obtained. Next, the terminal point data is transmitted to a system display computer 6 through a communication line 9. Then, the receiving of a receiving response from the system display computer 6 is processed. According to this method, indicating data, transmitted from the main computer 4 into the system display computer 6, are compressed and contracted whereby a transmitting time can be shortened. |
