Abstract:
1. A graphical user interface for providing real-time process information to a user with regard to a process that is operable under control of one or more process variables, the graphical user interface comprising: a scale extending along a gauge axis; one or more bars extending along the gauge axis with the scale, each bar representative of a set of high and low process limit values for a process variable, wherein the one or more bars extending along the gauge axis comprises: a first bar extending along the gauge axis, wherein a first end of the first bar is representative of an user set engineering hard high limit for the process variable and a second end of the first bar is representative of an user set engineering hard low limit for the process variable, wherein the first end and second end of the first bar representative of the engineering hard high and hard low limits define a range in which operator set high and low limits are set; and a second bar extending along the gauge axis, wherein a first end of the second bar is representative of the operator set high limit for the process variable and a second end of the second bar is representative of the operator set low limit for the process variable, wherein the first end and second end of the second bar representative of the operator set high and low limits define a range in which the process is free to operate, wherein each of the operator set high and low limits are adjustable so as to exert influence on the process; and a graphical shape displayed along the gauge axis representative of a current value of the process variable.
