PROBLEM TO BE SOLVED: To provide a process control device capable of easily performing a sure operation when a setting value (SV) and a control input (MV) are set from an HMI (Human-Machine Interface) device to a controller.SOLUTION: A setting value or a target value of a control input and an operation time width for reaching the target value are combinedly set in a controller that obtains a control operation quantity when a control object is controlled according to the setting value or the control input to be input. The process control device includes asymptotic processing means that causes the controller to perform asymptotic processing of the setting value or the control input by a gradient determined by the operation time width to the target value. |
