PURPOSE:To enahance the judgement of the state of control capacity, by providing a state data holding means, a memory means for storing medium cyclical data and a control apparatus for editing and displaying existing data on the basis of the indication of an operator. CONSTITUTION:The output of a process input apparatus 1 for inputting the state of a plant at the time of the operation/stoppage and the obstacle/normality of machinery is inputted to an input holding means 2 which in turn temporarily preserves of state data by main memory. The memory data of a memory apparatus 3 inputs the time of data to be displayed or a display form to a display control means 5 for controlling display from a means 4 such as a keyboard. State data can be displayed so as to be successively changed over a range from the past point of time to the present point of time by the operation way of the display control means 5. In addition, with due regard to a specific state amount or machinery, the change state thereof can be displayed as a table or graph. |
