1. A method, comprising:
- monitoring process variables in a process control system;
determining a current state of a first one of the process variables;
determining a trend associated with the first process variable;
generating a first graphic having visual content defining an outer boundary of the first graphic, the visual content of the first graphic including a set point indicator and a process variable indicator, the first graphic being dynamically adjustable to represent information associated with the first process variable, the information comprising the current state of the first process variable, a relative position of the first process variable with respect to a set point, and the trend of the first process variable, the trend of the first process variable represented by the visual content of the first graphic based on a slant of an edge of the outer boundary, the current state represented by the first graphic based on at least one of a shape of the outer boundary or the visual content within the outer boundary, the relative position of the first process variable with respect to the set point represented by the first graphic based on a relative position of the process variable indicator to the set point indicator; and
rendering the first graphic via a display, wherein the first graphic is utilized by an operator of the process control system to facilitate an assessment of a condition of the process control system and to facilitate trend-based monitoring and analysis of the condition of the process control system.

Abstract
Systems and methods to graphically display process control system information are disclosed. Some example methods include monitoring process variables in a process control system, determining a current state of a first one of the process variables, and determining a trend associated with the first process variable. Some such examples further include generating a first graphic representative of information associated with the first process variable, the information comprising the current state of the first process variable and the trend of the first process variable. Some example methods also include rendering the first graphic via a display.

17. A tangible machine readable storage device or disc comprising instructions that, when executed, cause a machine to at least:
-
monitor a process variable in a process control system; generate a dynamically adjustable icon, the icon having visual content defining an outer boundary of the icon, the visual content of the icon including a set point indicator and a process variable indicator, the visual content of the icon indicative of information associated with the process variable, the information including (1) a current state of the process variable represented by the visual content of the icon based on at least one of a shape of the outer boundary or the visual content within the outer boundary, (2) a relative position of the process variable with respect to a set point represented by the visual content of the icon based on a relative position of the process variable indicator to the set point indicator, and (3) a trend of the process variable represented by the visual content of the icon based on a slant of an edge of the outer boundary; and render the icon via a display, wherein the icon is utilized by an operator of the process control system to facilitate an assessment of a condition of the process control system and to facilitate trend-based monitoring and analysis of the condition of the process control system. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)

27. An apparatus comprising:
-
a processor to monitor a process variable in a process control system, the processor to generate a dynamically adjustable icon to graphically represent (1) a current state of the process variable based on at least one of a shape of an outer boundary of the icon or a first portion of visual content within the outer boundary, (2) a relative position of the process variable with respect to a set point based on a relative position of a process variable indicator included in the visual content to a set point indicator included in the visual content, (3) a projected state of the process variable based on at least one of the shape of the outer boundary or a second portion of the visual content within the outer boundary, and (4) a trend of the process variable based on an angle of an edge of the outer boundary; and a display to render the icon via an operator interface, wherein the icon is to be utilized by an operator of the process control system to facilitate an assessment of a condition of the process control system and to facilitate trend-based monitoring and analysis of the condition of the process control system. - View Dependent Claims (28, 29)
