Abstract

Control system with at least one control unit, a server computer, a first document in a markup language and a second document in a markup language for loading through a client computer, whereby the first document contains at least one field and the second document contains data for directing the field to an address in a control unit.

Claims

1-15. -15. (cancelled)

16. A method for transmission of a process value from a control unit to a client computer, comprising:

providing at least one access to a first document in a markup language of a server computer, the first document having at least one field for the process value;

providing at least one access to a second document in a markup language, with the second document having data for assigning the field to an address of the control unit;

assigning the field to the address of the control unit;

assigning the second document to the first document, whereby a database is accessed on behalf of the server computer for the purpose of assigning;

querying the process value from the address; and

transmitting the process value from the server computer to the client computer.

18. A method according to claim 16, wherein the first document comprises a script.

19. A method according to claim 16, wherein a script of the first document executes a query of the database to determine the assignment of the first document to a second document.

20. A method according to claim 16, wherein the first document comprises a pointer to the second document.

21. A method according to claims 16, wherein the data for assigning the field to an address of the control unit contains an address of the control unit.

22. A method according to claims 16, wherein the second document assigns a designation to the field of the first document and a database of the server computer is queried using a script, the database containing an assignment of the designation to an address of the control unit.

32. A method according to claim 18, wherein the script of the first document executes a query of the database in order to determine the assignment of the first document to a second document.

35. A method according to claim 18, wherein the first document contains a pointer to the second document.

38. A method according to claim 18, wherein the data for assigning the field to an address of the control unit contains an address of the control unit.

41. A method according to claim 18, wherein the second document assigns a designation to the field of the first document and a database of the server computer is queried using a script, said database containing an assignment of the designation to an address of the control unit.

17. A method for transmission of an input value from a client computer to a control unit, comprising:

providing at least one access to a first document in a markup language of a server computer, the first document having at least one field for the input value;

providing at least one access to a second document in a markup language, the second document containing data for assigning the field to an address of the control unit;

entering the input value into the field;

assigning the field to the address of the control unit;

assigning the second document to the first document, whereby a database is accessed on behalf of the server computer for the purpose of assigning; and

transmitting the input value from the server computer to the control unit.

29. A method according to claim 17, wherein the first document comprises a script.

30. A method according to claim 17, wherein a script of the first document executes a query of the database to determine the assignment of the first document to a second document.

31. A method according to claim 29, wherein the script of the first document executes a query of the database to determine the assignment of the first document to a second document.

33. A method according to claim 17, wherein the first document contains a pointer to the second document.

34. A method according to claim 33, wherein the pointer to the second document is a URL.

36. A method according to claim 17, wherein the data for assigning the field to an address of the control unit contains an address of the control unit.

37. A method according to claim 29, wherein the data for assigning the field to an address of the control unit contains an address of the control unit.

39. A method according to claim 17, wherein the second document assigns a designation to the field of the first document and a database of the server computer is queried using a script, said database containing an assignment of the designation to an address of the control unit.

40. A method according to claim 29, wherein the second document assigns a designation to the field of the first document and a database of the server computer is queried using a script, said database containing an assignment of the designation to an address of the control unit.

23. A computer program product comprising computer-readable means for performing a method for transmission of a process value from a control unit to a client computer, the method comprising:

providing at least one access to a first document in a markup language of a server computer, the first document having at least one field for the process value;

providing at least one access to a second document in a markup language, with the second document having data for assigning the field to an address of the control unit;

assigning the field to the address of the control unit;

assigning the second document to the first document, whereby a database is accessed on behalf of the server computer for the purpose of assigning;

querying the process value from the address; and

transmitting the process value from the server computer to the client computer.

43. A computer program product according to claim 23, wherein the program for performing the method is executed on a control system.

24. A control system comprising:

at least one control unit;

a server computer;

a first document in a markup language and a second document in a markup language for loading by a client computer, the first document comprising at least one field; and

a first database for assigning the first and the second document on the server computer, the second document comprising data for assigning the field to an address of the control unit.

25. A control system according to claim 24, wherein the first document comprises a script.

26. A control system according to claim 24, wherein the first document has a pointer to the second document.

27. A control system according to claim 24, wherein the data for assigning the field to an address of the control unit has an address of the control unit.

28. A control system according to claim 24, wherein the data for assigning the field to an address of the control unit assigns a designation to the field and having a second database on the server computer for assigning the designation to the address of the control unit.

45. A control system according to claim 25, wherein the first document has a pointer to the second document.

46. A control system according to claim 45, wherein the pointer is a URL.

47. A control system according to claim 26, wherein the pointer is a URL.

42. A computer program product comprising computer-readable means for performing a method for transmission of an input value from a client computer to a control unit, comprising:

providing at least one access to a first document in a markup language of a server computer, with the first document having at least one field for the input value;

providing at least one access to a second document in a markup language, the second document containing data for assigning the field to an address of the control unit;

entering the input value into the field;

assigning the field to the address of the control unit;

assigning the second document to the first document, whereby a database is accessed on behalf of the server computer for the purpose of assigning; and

transmitting the input value from the server computer to the control unit.

44. A computer program product according to claim 42, wherein the program for performing the method is executed on a control system.
