Abstract
A man-machine interface system for a process controller according to the present invention enables its direct picture select button function to be effectively used by each user, and is improved in the operability of picture selection for interrupt display. The system includes a display, a picture data controller for controlling the pictures, which are displayed on the display, and at least one direct picture select button for requesting the display of an interrupt picture on the display to set control requirements and monitor operating conditions with the controller. In response to the interrupt picture display request by the button, a specified picture is displayed as an interruption on the display. The system further includes an interrupt picture definition table for setting by the user to changeably define on a user's setting picture the picture for interrupt display. The interrupt picture set by the user can be displayed independently of the initialization hierarchy by only operating the button.
