<p>PURPOSE:To improve operability by displaying plant data which should be monitored by an operator's CRT touch operation. CONSTITUTION:By the operator's touch operation, the X-Y coordinate at a touch position is outputted to a touch input processing part 11 through the touch panel 15 of the CRT display unit 5 of plant data display device 1 so as to judge from the Y coordinate whether it is the selection of the kind of a sensor in the lower part of a screen or the requirement of the display of the plant data in the upper part of the screen. Then, the X-Y coordinate at the touch position is outputted to a sensor position display data generation part 12 or a plant data display data generation part 13 according to the kind of the requirement. The generation part 12 decides the kind of the sensor at the touch position, fetches the information on the sensor of the same kind from a sensor information storage part 14 and outputs a screen No. and the kind of the sensor to the generation part 13. The content of the storage part 14 is retrieved based on the screen No., the kind of the sensor and the X-Y coordinate at the touch position and the selected information on the sensor is fetched. The plant data is fetched from a plant data storage part 10 by a CRT display processing part 4 and outputted to the display unit 5, thereby improving the operability.</p> |
