<p>PROBLEM TO BE SOLVED: To reduce the processing load of a man-machine device and to attain an inexpensive, highly functional and highly accurate plant monitor and control equipment by allowing a data server device to edit process data required for display in the man-machine device. SOLUTION: A control device 30 stores a sensor signal from a plant equipment 1, a control value obtained from a control operation part in the device 30 and received switch information in a transmission memory at a fixed period and transmits the stored data to a data server device 60 through a transmission line 52. In the device 60, the transmission process data are stored in a prescribed address of a scanning memory in an edition means 62. The means 62 edits data required for the man-machine device 40 and transmits the edited data to the device 40 through a transmission line 51. The signal transmitted to the device 40 is stored in an input memory in a data I/O device 13. A display control means in the device 13 reads out the contents of the input memory and displays an equipment symbol for the equipment 1 to a display means 11 while reflecting a sensor detection data and a control value.</p> |
