摘要： A process controller having a setting section for giving a target value for a fixed period of time, a control section including a predicting section for predicting a process response for the fixed time period in accordance with a current value of a process control amount and a virtual value of an operation amount; a quantitating section for quantitating a difference between the target value and the result by the predicting section; a calculating section for calculating a basic signal of the operation amount in accordance with the quantitated result, and an optimizing section including a predicting section for predicting a process response for the fixed time period with a control amount and an initial operation amount of the process; another quantitating section for quantitating a difference between the prediction and the target value, a calculating section for calculating the operation amount in accordance with the second quantitated result; and a section for performing control in such a way that the quantitating result and a predetermined evaluation criterion are compared with each other to perform an evaluation. The calculated result of the operation amount is repeatedly applied to the predicting section until the evaluation criterion is satisfied, a correcting signal used for optimizing the operation amount is obtained from a value of the operation amount when the quantitated result satisfies the criterion, and the correcting signal is added to a basic signal of the control section, and the adding result is output to the process.

摘要： A system and a method of monitoring and displaying in which control screen indicating a control data of a control device for process control displayed on the display screen of a display unit by a touch operation on a diagram of the control device, the control data being further selected by another touch operation. The display condition of the control data display area thus changes, the operator being permitted to visually check whether the operation has been selected correctly. After visual confirmation, a switch disposed outside of the display screen and corresponding to the called control screen is operated to start the operation of the control device determined for control for the first time at this time point. In case of a combined display of a control device and a control screen, on the other hand, a first display unit is utilized such that the called control screen is displayed at a position far from the control device to be controlled, thereby not hiding the control device display. The control screen may be moved to a given position on the system diagram. A second display unit is utilized such that the original system diagram is displayed in a reduced form in combination with and not superimposed on the called control screen. The control screen and the control-related screen are called repeatedly so that when the reduction rate of the original system diagram exceeds a critical value, the reduction rate is fixed to a predetermined value and the control screens are displayed in scroll.

摘要： A method and apparatus for displaying on a display screen the controlling circuit in a plant controlling system for controlling a plant by a controller using a microcomputer. The display screen is segmented into a software region and a hardware region. The software circuit which is realized by software is displayed in the software region, and the hardware circuit related to the software circuit is displayed in the hardware region. The information, which is plotted during the interactive process and is displayed in the software regions, is automatically translated into a program for controlling the controller. Operation data of the plant is also given on the display screen. Desired circuit elements of the software circuit may be selected to change parameters of the circuit elements. Maintenance work can be carried out while observing the indication on the display screen without any aid of documents such as the maintenance manual or the like.
