PURPOSE:To recognize each curve while maintaining the continuity of the curve by adding an identification mark to the curve which shows the process quantity of a plant. CONSTITUTION:The data supplied from a plant 1 is stored to a data file 4 periodically by a data collecting part 3 via an input controller 2. Then a curve data processing part 5 converts the data of the file 4 into the curve display data. A curve identification mark is added to the converted curve display data through a mark pattern adding part 10. Then this display data is displayed by a CRT display device 8. In such a way, it is possible to identify each curve while maintaining the continuity of the curve owing to an identification mark added. |
