Display device for indicating the value of a parameter in a process plant
A display device is described for indicating the value of a parameter in a process plant having an indicator and alarm system, comprising: a display screen; digital processing means for producing a plurality of display fields on the display screen, receiving input signals originating from sensors responsive to changes in the parameter, computing derived values from the input signals, and producing output value images in some of the display fields commensurate with respective input signals and derived values; some of said fields defining touch-sensitive selection means for selecting particular of said fields and particular of said values for display on said screen; herein a first set of said fields define a first display page and a second set of fields define a second display page, (a) the first and second display pages each having, a process value field for displaying one output value image, a quality field for displaying the quality of said one output value, a menu field defining a touch-sensitive menu selection target whereby the user can alternate the display between said first and second pages, (b) the first display page having, a plurality of touch-sensitive sensor fields for displaying the identity of each sensor that generates an input signal for said parameter, such that touching one of said sensor fields causes the display of the corresponding value image in said process value field, a touch sensitive calculation field for causing the display of a derived value of said parameter in said process value field, a touch sensitive over side field whereby the operator can specify which of the output values of said display device is to be used as a representative value of the parameter in the indicator and alarm system, (c) the second display page having an analog field in which at least one analog representation of the value in the process value field is displayed.
