Control value-setting apparatus for process controller

摘要

In a process controller setting apparatus comprising a display 19 with an associated touch panel 21, the value of a control parameter according to which the system is operating is stored in a memory and displayed on the display 19. The value of the control parameter is adjusted each time the user adjusts the value of the parameter on the display without the need to confirm the change. When a control parameter to be adjusted is selected by touching the touch panel in area a, a dialog window b is opened and the associated control parameter is adjusted by pressing area c. Selecting a different parameter a to be adjusted displays its associated dialog window whilst closing the window previously open.
