Abstract

A control system for an industrial plant receives plant data and combines that plant data with a plurality of graphical patterns representing the plant. In this way a series of prepared displays are created to be displayed fox a user of the control system. If the user wants to simplify one or more of the displays, in order to make it more clear, the control system has means for modifying the displays, and displaying that modified display. The modification may be one of a number of possibilities such as deletion (masking) part or all of the display. In this way, the full plant information may be presented, or more limited information may be presented, e.g. to a more experienced user.

means for selecting one of said prepared displays;

means for modifying said selected one of said prepared displays to generate a modified display, said modifying means including means for performing at least one of masking and reducing an intensity of unnecessary information in said selected one of said prepared displays to generate said modified display; and

means for displaying said modified display.

2. A control system according to claim 1, wherein said means for modifying said selected one of said prepared displays further includes means for performing at least one modification operation selected from the group consisting of translation, change of colour, magnification, and periodic changing of selected information in said selected one of said prepared displays to generate said modified display.

3. A control system according to claim 1, further comprising means for calculating further plant data representing further operating parameters of said plant from said plant data, wherein said modifying means further includes means for incorporating at least some of said further plant data in said selected one of said prepared displays to generate said modified display.

4. A control system according to claim 1, further comprising printing means for providing a hard-copy print of said modified display.

5. A control system according to claim 4, further comprising means for enabling an operator to activate said printing means.

6. A control system according to claim 4, further comprising means for automatically activating said printing means.

7. A control system according to claim 1, further comprising printing means for providing a hard-copy print of said selected one of said prepared displays.

8. A control system according to claim 7, further comprising means for enabling an operator to activate said printing means.

9. A control system according to claim 7, further comprising means for automatically activating said printing means.

10. A control system according to claim 1, further comprising means for inputting information relating to experience and a skill level of an operator, wherein said means for modifying said selected one of said prepared displays further includes means for modifying said selected one of said prepared displays based on said information to generate said modified display, whereby said modified display is at least partially determined by the experience and the skill level of the operator.

11. A control system according to claim 1, further comprising:

means for selecting a further one of said prepared displays; and

means for modifying said further one of said prepared displays to generate a further modified display; and

wherein said means for displaying said modified display includes means for displaying said modified display and said further modified display simultaneously.

12. A control system according to claim 1, further comprising means for receiving a modification request from an operator, wherein said modifying means further includes means for modifying said selected one of said prepared displays in response to said modification request.

13. A control system according to claim 1, wherein said modifying means further includes means for automatically specifying said unnecessary information in said selected one of said prepared displays based on a change in a state of said plant.

14. A control system according to claim 1, wherein said unnecessary information in said selected one of said prepared displays relates to at least one inactive portion of said plant.

15. A control system according to claim 1, further comprising means for detecting whether or not an operator is present, wherein at lest said displaying means does not operate if the detecting means detects that an operator is not present.

16. A control system for an industrial plant, comprising:

means for generating a plurality of prepared displays, each of said prepared displays including at least one graphical pattern representing said plant and a plurality of plant data representing operating parameters of said plant;

means for selecting one of said prepared displays;

means for selecting only some of said plant data of said selected one of said prepared displays; and

means for displaying said selected one of said prepared displays as a modified display wherein said selected plant data of said selected one of said prepared displays is visually distinguished from other plant data of said selected one of said prepared displays.

17. A control system according to claim 16, wherein said means for selecting only some of said plant data of said selected one of said prepared displays includes means for receiving a request from an operator specifying which of said plant data of said selected one of said prepared displays is to be selected and visually distinguished when said selected one of said prepared displays is displayed by said displaying means as said modified display.

18. A method of operating an industrial plant, comprising the steps of:

receiving a multiplicity of plant data representing operating parameters of said plant;

storing a plurality of graphical patterns representing said plant;

generating a plurality of prepared displays, each of said prepared displays including at least one of said graphical patterns and at least some of said plant data;

selecting one of said prepared displays;

modifying said selected one of said prepared displays to generate a modified display, said modifying step including the step of performing at least one of masking and reducing an intensity of unnecessary information in said selected one of said prepared displays to generate said modified display; and

displaying said modified display.

19. A method according to claim 18, wherein said step of modifying said selected one of said prepared displays further includes the step of performing at least one of translation, change of colour, magnification, and periodically changing selected information in said selected one of said prepared displays to generate said modified display.

20. A method according to claim 18, further comprising the step of calculating further plant data representing further operating parameters of said plant from said plant data, wherein said modifying step further includes the step of incorporating at least some of said further plant data in said selected one of said prepared displays to generate said modified display.

21. A method according to claim 18, further comprising the step of receiving a modification request from an operator, wherein said modifying step further includes the step of modifying said selected one of said prepared displays in response to said modification request.

22. An industrial plant comprising:

a plurality of plant components each having operating parameters;

a control system for monitoring said plant components;

means for detecting said operating parameters of the plant components and converting the detected operating parameters to a multiplicity of plant data; and

means for transmitting said multiplicity of plant data to said control system, wherein said control system monitors said plant components based on said multiplicity of plant data;

wherein said control system includes;

means for receiving said multiplicity of plant data;

means for storing a plurality of graphical patterns representing said plant;

means for generating a plurality of prepared displays, each of said prepared displays including at least one of said graphical patterns and at least some of said plant data;
