Abstract

A method for monitoring operation behaviour of a component of an industrial plant is provided. Parameter identifiers of operation parameters of the industrial plant are read from an element of a control system of the plant. Some of these parameter identifiers are selected and the selected parameter identifiers are forwarded to an element of the control system. Further, a time of a specified operation of the component is defined and behaviour of the selected parameters of the component in the defined time is used as guide model for monitoring selected parameters of the component during component operation.

Claims

1-10. -10. (canceled)

11. A method for monitoring operation behaviour of a component of an industrial plant, the method comprising:

reading parameter identifiers of operation parameters of the industrial plant from an element of a control system of the plant;

selecting parameter identifiers;

forwarding the selected parameter identifiers to an element of the control system;

defining a time of a specified operation of the component; and

using a behaviour of the selected parameters in the defined time as guide model for monitoring selected parameters during component operation.

12. The method according to claim 11, wherein the read parameter identifiers are transferred into an editable form.

13. The method according to claim 11, wherein the selecting of parameter identifiers is a filtering process with a filter operator.

14. The method according to claim 11, wherein the identifiers are processed into a machine readable code before forwarding the selected parameter identifiers to the control system.

15. The method according to claim 11, wherein the selected parameter identifiers are given back to the control system together with commands for the control system to generate a structure of control system modeling elements representing the parameters of the selected parameter identifiers.

16. The method according to claim 15, wherein the elements each are state estimators for generating expectancy values for the respective parameter.

17. The method according to claim 15, wherein the structure comprises a model of a part of the control system.

18. The method according to claim 16, wherein the structure comprises a model of a part of the control system.
