Abstract

A process control monitoring system for a process control plant uses graphic trend symbols to assist in detecting and monitoring trends of process variables within the process control plant. A graphic display application within the process control monitoring system may implement and display each graphic trend symbol to graphically indicate or encapsulate current trend and value information of a process variable within the process control plant. The graphic display application may display the graphic trend symbol in a spatially realistic location within a graphical representation of the process control plant while maintaining the hierarchical structure or each hierarchical level of the process plant. The graphic display application may also include a zoom feature that enables a user to quickly drill down through tend data to obtain more information and to support problem identification and diagnosis tasks.

Claims

1. A method in a computing device for providing a process variable pane for monitoring process variables within a graphical depiction of a process control plant, the method comprising:

displaying a graphical depiction of a process control plant that includes one or more graphic trend symbols, each graphic trend symbol (i) associated with a process variable within the graphical depiction of the process control plant and (ii) graphically representing process control information related to the associated process variable;

displaying one or more process variable panes associated with the displayed graphical depiction of the process control plant, each process variable pane including one or more process variable selector icons that correspond to the one or more process variables displayed within the graphical depiction of the process control plant, each process variable selector icon including a graphic trend symbol that corresponds to one of the graphic trend symbols displayed within the graphical depiction of the process plant;

receiving a selection of one of the process variable selector icons associated with a first one of the process variable panes for a particular process variable; and

highlighting, in response to receiving the selection, (i) the corresponding graphic trend symbol in at least a second one of the process variable panes and (ii) the corresponding graphic trend symbol in the graphical depiction of the process control plant.

2. The method of claim 1, wherein displaying each process variable selector icon includes displaying one or more process variable attributes associated with the process variable that is associated with the process variable selector icon.

3. The method of claim 2, further comprising displaying each process variable selector icon of a particular process variable pane with the same number of process variable attributes, each process variable pane including process variable selector icons that include a unique number of process variable attributes from the other process variable panes.

4. The method of claim 3, wherein displaying one or more process variable panes includes displaying the one or more process variable panes within a fixed, bounded area.

5. The method of claim 4, further comprising displaying (i) each process variable selector icon within each process variable pane that is associated with a process variable in a critical state and (ii) the one or more process variable attributes associated with each process variable selector icon.

6. The method of claim 4, further displaying as many process variable selector icons for one process variable panes while remaining within the fixed, bounded area.

7. The method of claim 4, further comprising displaying as many process variable selector icons and corresponding one or more process variable attributes in one of the process variable panes while remaining within the fixed, bounded area.

8. The method of claim 1, wherein the receiving the selection includes receiving a hover event associated with the first one of the process variable selector icons.

9. The method of claim 2, wherein the process control attributes include at least one of a parameter name, a type of engineering unit, an alarm trip point, a digital output process variable value, a trend graph, or an alarm tag.

16. The computer-readable storage medium of claim 4, further comprising instructions for displaying as many process variable selector icons and corresponding one or more process variable attributes in one of the process variable panes while remaining within the fixed, bounded area.

10. A computer-readable storage medium having stored thereon a set of instructions, executable by a processor, for providing, via a computing device having a user interface, a process variable pane for monitoring process variables within a graphical depiction of a process control plant, the instructions comprising:

instructions for displaying a graphical depiction of a process control plant that includes one or more graphic trend symbols, each graphic trend symbol (i) associated with a process variable within the graphical depiction of the process control plant and (ii) graphically representing process control information related to the associated process variable;

instructions for displaying one or more process variable panes associated with the displayed graphical depiction of the process control plant, each process variable pane including one or more process variable selector icons that correspond to the one or more process variables displayed within the graphical depiction of the process control plant, each process variable selector icon including a graphic trend symbol that corresponds to one of the graphic trend symbols displayed within the graphical depiction of the process plant;

instructions for receiving a selection of one of the process variable selector icons associated with a first one of the process variable panes for a particular process variable; and

instructions for highlighting, in response to receiving the selection, (i) the corresponding graphic trend symbol in at least a second one of the process variable panes and (ii) the corresponding graphic trend symbol in the graphical depiction of the process control plant.

11. The computer-readable storage medium of claim 10, wherein the instructions for displaying each process variable selector icon includes instructions for displaying one or more process variable attributes associated with the process variable that is associated with the process variable selector icon.

12. The computer-readable storage medium of claim 11, further comprising instructions for displaying each process variable selector icon of a particular process variable pane with the same number of process variable attributes, each process variable pane including process variable selector icons that include a unique number of process variable attributes from the other process variable panes.

13. The computer-readable storage medium of claim 12, wherein the instructions for displaying one or more process variable panes includes instructions for displaying the one or more process variable panes within a fixed, bounded area.

14. The computer-readable storage medium of claim 13, further comprising instructions for displaying (i) each process variable selector icon within each process variable pane that is associated with a process variable in a critical state and (ii) the one or more process variable attributes associated with each process variable selector icon.

15. The computer-readable storage medium of claim 13, further comprising instructions for displaying as many process variable selector icons for one process variable panes while remaining within the fixed, bounded area.

17. The computer-readable storage medium of claim 10, wherein the instructions for receiving the selection includes instructions for receiving a hover event associated with the first one of the process variable selector icons.

18. The computer-readable storage medium of claim 11, wherein the process control attributes include at least one of a parameter name, a type of engineering unit, an alarm trip point, a digital output process variable value, a trend graph, or an alarm tag.
