Abstract

PURPOSE:To memorize the trend of the process quantity near the present time in contradistinction to the time and then to secure monitor for the past history also in contradistinction to the time for the display unit which gives a graph display of the history to the pressure of the plant as well as the process quantity of the temperature, etc. CONSTITUTION:Process input device 1 which supplies process value A, B, C ... given from the plant is provided along with electronic computer 2 which gives an operation to the trend value of value A, B, C ... based on value A, B, C ..., and thus the trend graph of A, B, C ... is displayed on picture display unit 3. In such trend graph display unit, all process value A, B, C ... which are capable of trend graph display are reserved at process value memory part 24 from the plant through device 1 and via process reserving function part 21. And when a request is given ordering a display at unit 3 from manual input part 4, the trend graph is displayed through trend graph fixed display function part 23 along with the time of a fixed cycle.
