Abstract

A system for automation of technical processes and/or experiments having a measurement unit and a control unit which are connected to sensors and actuators of the process or of the experimental unit via measurements and control channels, having at least one library that contains visualization objects and control modules, and having software that manages the system. The system enables the user to develop applications without knowledge of programming techniques. Technologists, chemists, scientists using the system no longer need to rely on the aid of programming specialist.

Claims

1. A system for automation of a technical process or an experimental procedure having sensors and actuators,

a measurement and control unit connected to said sensors and actuators by measurement and control lines,

at least one library containing visualization objects and control modules, and

software operatively associated with said measurement and control unit and said library, said software managing said system.

2. The system for automation of claim 1 and further comprising control modules predefined as to their function and having windows, said control modules being linked with visualization objects facilitating the performance of predetermined sub-tasks, and wherein, upon the choice of one of said visualization objects, the linked control module is shown in one of said windows.

3. The system for automation of claim 2 wherein the properties of said visualization objects can be changed by said control modules and wherein said control modules include operator transactions affecting the automated procedure.

4. The system for automation of claim 1 wherein the properties of said visualization objects can be changed by said control modules and wherein said control modules include operator transactions affecting the automated procedure.

5. The system for automation of claim 1 wherein said library includes control modules not linked with visualization objects.

6. The system for automation of claim 1 wherein said control modules include sequence modules, event modules and function modules.

7. The system for automation of claim 6 wherein said sequence modules and said event modules can be chained vertically and are responsible for process guidance and wherein said function modules can be chained horizontally and work in parallel with said vertically chained modules without taking over process guidance.

8. The system for automation of claim 7 wherein one of said modules can be invoked during runtime by any other module according to the chaining.

9. The system for automation of claim 7 wherein when said modules are vertically chained, said procedure takes a vertical course from top to bottom.

10. The system for automation of claim 7 wherein the direction of chaining can be interchanged without change of the function.

11. The system for automation of claim 6 wherein an event module can be invoked by a cyclical interrupt and break into any one of said sequence modules, function modules and other of said event modules, the interrupted workings of said modules being continued after the event has been worked through.

12. The system for automation of claim 6 wherein said control modules contain parts symbolic figures and assigned scripts.

13. The system for automation of claim 6 wherein said sequence modules monitor process guidance, wherein event modules break into other control modules at arbitrary points in time and take over process guidance during the interruption, and wherein function modules measure and control.

14. The system for automation of claim 1 wherein distinct symbolic figures are allocated to said control modules as recognition features.

15. The system for automation of claim 14 wherein said symbolic figures can be displayed in a module window and can be chained vertically and horizontally according to fixed rules.

16. The system for automation of claim 1 wherein said control modules contain program instructions and keywords.

17. The system for automation of claim 16 wherein said keywords function as placeholders for program instructions, variables and further keywords.

18. The system for automation of claim 16 wherein access to knowledge lists, containing program instructions, variables and further keywords, is opened by emphasized keywords.

19. The system for automation of claim 18 wherein program instructions, variables and keywords which are selected automatically replace the original keyword.

20. The system for automation of claim 19 wherein replacement of keywords is may be continued until all keywords have been replaced by program instructions, variables or constants.

21. The system for automation of claim 19 wherein the program instructions of said control modules are queries and actions.

22. The system for automation of claim 21 wherein the queries contain an instruction with an appropriate formulation “

If (logical operation) then” and

with the options “

If now but not previously then” and

“

If not then,”

by which the exact point in time at which the event arose can be detected.

23. The system for automation of claim 16 wherein the individual concepts of the script language, said as keywords, instructions, variables and constants, are visibly displayed as graphical objects.

24. The system for automation of claim 23 wherein script objects are arranged in line-oriented fashion.

25. The system for automation of claim 24 wherein image-oriented symbols are insertable into script objects.
