Abstract

A computer-implemented method for representing operator control information in the context of operator control and monitoring of a technical installation is proposed, which has at least one operator station server and one operator station client, wherein at least one measurement value of at least one technical object of the technical installation is received via the operator station server, a trend progression of the measurement value is generated in the event that an alarm, which relates to the measurement value, occurs in the operator station server, the trend progression from the operator station server is transferred to the operator station client, and the trend progression is visually presented to an operator of the technical installation in a trend progression diagram.

First claim

What is claimed is:

1. A computer-implemented method for representing operator control information within a context of operator control and monitoring of a technical installation having at least one operator station server and one operator station client, the method comprising:
a) receiving at least one measurement value of at least one technical object of the technical installation via the at least one operator station server, a visualization service and an alarm service being integrated into said at least one operator station server, and a subservice being integrated into a trend service which forms part of the visualization service;
b) generating a trend progression of the measurement value in an event of an alarm which relates to the measurement value occurring in the at least one operator station server, the alarm service detecting triggering of the alarm and reporting said triggering to the subservice of the trend service;
c) transferring the generated trend progression from the at least one operator station server to the operator station client; and
d) visually presenting the transferred trend progression to an operator of the technical installation in a trend progression diagram to permit analysis of the technical object by interacting with the trend progression diagram to open a faceplate of the technical object, the trend progression diagram including a current progression of the measurement value and including a previous trend progression of a measured value provided as a result of a termination of an associated alarm.

2. The computer-implemented method as claimed in claim 1 , wherein the trend progression is generated, transferred to the operator station client and visually provided at the operator station to the operator until the alarm is terminated.

3. The computer-implemented method as claimed in claim 1 , wherein in an event of the operator interacting with the trend progression diagram said operator is visually provided via the operator station client with a digital representation of the technical object upon which the trend progression diagram is based.

4. The computer-implemented method as claimed in claim 2 , wherein in an event of the operator interacting with the trend progression diagram said operator is visually provided via the operator station client with a digital representation of the technical object upon which the trend progression diagram is based.

5. The computer-implemented method as claimed in claim 1 , wherein the trend progression of the measurement value is stored in an archive of a control system of the technical installation.

6. The computer-implemented method as claimed in claim 1 , wherein the trend progression of the measurement value is generated partially or completely via an interpolation of historical values of the measurement value.

7. A control system for a technical installation having at least one operator station server and one operator station client, the at least one operator station server being configured to generate at least one alarm which relates to a measurement value of a technical object of the technical installation which is connectable to the control system, and the at least one operator station server being configured to receive the measurement value from the technical object to generate a trend progression of the measurement value and to transfer the trend progression to the operator station client to present the trend progression to an operator of the technical installation visually in a trend progression diagram to permit analysis of the technical object by interacting with the trend progression diagram to open a faceplate of the technical object, a visualization service and an alarm service being integrated into said at least one operator station server, and a subservice being integrated into a trend service which forms part of the visualization service;
wherein the at least one operator station server is further configured to generate the trend progression of the measurement value and transfer said generated trend progression to the operator station client only if an alarm which relates to the measurement value occurs in the at least one operator station server, the alarm service detecting triggering of the alarm and reporting said triggering to the subservice of the trend service; and
wherein the trend progression diagram includes a current progression of the measurement value and includes a previous trend progression of a measured value provided as a result of a termination of an associated alarm.

8. The control system as claimed in claim 7 , wherein the at least one operator station server is further configured to continue generating the trend progression and transfer said generated trend progression to the operator station client for visual display to the operator until the alarm is terminated.

9. The control system as claimed in claim 7 , wherein the operator station client is further configured such that in the event that the operator interacts with the trend progression diagram said operator is visually provided with a digital representation of the technical object upon which the trend progression diagram is based.

10. The control system as claimed in claim 8 , wherein the operator station client is further configured such that in the event that the operator interacts with the trend progression diagram said operator is visually provided with a digital representation of the technical object upon which the trend progression diagram is based.

11. The control system as claimed in claim 7 , wherein the at least one operator station server is further configured to generate the trend progression of the at least one measurement value partially or completely via an interpolation of historical values of the measurement value.

12. The control system as claimed in claim 8 , wherein the at least one operator station server is further configured to generate the trend progression of the at least one measurement value partially or completely via an interpolation of historical values of the measurement value.

13. The control system as claimed in claim 8 , wherein the at least one operator station server is further configured to store the trend progression of the at least one measurement value in an archive of the control system of the technical installation.

14. The control system as claimed in claim 9 , wherein the at least one operator station server is further configured to store the trend progression of the at least one measurement value in an archive of the control system of the technical installation.

15. The control system as claimed in claim 11 , wherein the at least one operator station server is further configured to store the trend progression of the at least one measurement value in an archive of the control system of the technical installation.

16. The control system as claimed in claim 7 , wherein the technical installation comprises a manufacturing installation or process installation.

17. The control system as claimed in claim 9 , wherein the at least one operator station server is further configured to generate the trend progression of the at least one measurement value partially or completely via an interpolation of historical values of the measurement value.

18. The control system as claimed in claim 7 , wherein the at least one operator station server is further configured to store the trend progression of the at least one measurement value in an archive of the control system of the technical installation.
