Abstract

A method of displaying data corresponding to a procedure is provided where all of the data required to follow the procedure is displayed together with abbreviated text corresponding to the procedure. Text and data corresponding to only a portion of the procedure is displayed at any given time. Additional information related to several consecutive steps of the procedure which appear on separate screens is displayed continuously to one side of the screen. Additional data may be selected to displayed prior to returning to the original screen.

Claims

1. A method of displaying data related to a procedure for operating a complex facility, comprising the steps of:

(a) receiving equipment data indicating operational status of equipment in the complex facility;

(b) displaying text corresponding to a portion of the procedure for operating the complex facility; and

(c) displaying, simultaneously with the text in step (b), the equipment data received in step (a) and having a fixed relationship to the portion of the procedure.

2. A method as recited in claim 1, wherein the equipment data displayed in step (c) is displayed regardless of whether the complex facility is operating in a critical range.

3. A method as recited in claim 2, further comprising the steps of:

(d) providing access, via a selection indication provided by a human operator, to additional items of the equipment data; and

(e) displaying selected additional items of equipment data in response to the selection indication.

4. A method as recited in claim 3, wherein step (e) comprises displaying the selected additional items of equipment data using a graph.

5. A method as recited in claim 4,

further comprising the step of (f) storing at least a portion of the equipment data over a period of time greater than one day as historical data,

wherein step (d) comprises providing access to the historical data, and

wherein step (e) comprises displaying selected items of the historical data in response to the selection indication.

6. A method as recited in claim 2, further comprising the step of (d) displaying a first set of additional items of the equipment data, commonly related to a sequence of consecutive steps in the procedure, throughout said displaying of the text corresponding to the sequence of consecutive steps in step (b).

7. A method as recited in claim 6, further comprising the steps of:

(e) providing access, via a selection indication, to a second set of additional items of the equipment data; and

(f) displaying selected additional items from the second set of additional items of the equipment data in response to the selection indication.

8. A method as recited in claim 7, wherein the first and second sets of additional data are related.

9. A method as recited in claim 8,

wherein said displaying in steps (b), (c) (f) are performed using a screen, and

wherein said method further comprises the step of (g) inputting the selection indication by effectively making contact with the screen substantially at a location corresponding to the display of at least one item in the first set of the additional items of the equipment data.

10. A method as recited in claim 9, wherein the at least one item provides a summary of the first set of the additional items of equipment data.

11. A method as recited in claim 6, further comprising the step of (e) displaying a second set of additional items of the equipment data, immediately prior to said displaying in step (b) of a sub-set of the sequence of consecutive steps in the procedure, the sub-set being commonly related to the second set of additional items of the equipment data.

12. A method as recited in claim 11, further comprising the steps of:

(f) scrolling, in response to a first control indication, the text displayed in step (b) and the items related thereto, displayed in step (c), to display text corresponding to a different portion of the procedure, the second set of additional items of the equipment data scrolling off with the beginning of the sub-set of the sequence of consecutive steps; and

(g) returning, in response to a second control indication, directly to the second set of additional items of the equipment for display thereof.

13. A method as recited in claim 2, further comprising the step of (d) displaying a diagram of the complex facility in response to a control indication.

14. A method as recited in claim 2, further comprising the step of (d) displaying an instruction to obtain additional information from another source when the additional information is required to perform the portion of the procedure and the additional information is not included in the equipment data.

15. An apparatus for displaying data related to a procedure for operating a complex facility, comprising:

data acquisition means for receiving equipment data indicating operational status of equipment in the complex facility; and

display means for displaying text corresponding to a portion of the procedure for operating the complex facility and for simultaneously displaying the equipment data received by said data acquisition means and having a fixed relationship to the portion of the procedure regardless of whether the complex facility is operating in a critical range.

16. An apparatus as recited in claim 15,

further comprising access means for providing access, via a selection indication provided by a human operator, to additional items of the equipment data, and

wherein said display means displays selected additional items of equipment data in response to the selection indication.

17. An apparatus as recited in claim 16,

further comprising storage means for storing at least a portion of the equipment data over a period of time greater than one day as historical data,

wherein said access means provides access to the historical data, and

wherein said display means displays selected items of the historical data in response to the selection indication.

18. An apparatus as recited in claim 15, wherein said display means displays a first set of additional items of the equipment data, commonly related to a sequence of consecutive steps in the procedure, while the text corresponding to the sequence of consecutive steps is displayed, and displays a second set of additional items of the equipment data immediately prior to a sub-set of the sequence of consecutive steps in the procedure, the sub-set being related to the second set of additional items of the equipment data.
