Abstract

Applications to be connected, particularly MES (manufacturing execution system) applications, as well as the communications mechanisms are depicted in the object model of the framework (IF; IF meaning industrial framework) by using wrappers and/or adapters and, as a result, can be manipulated in a uniformly homogenous manner in the framework. The invention is advantageous in that the very heterogeneous structures of the applications are depicted on a common model and can be comfortably and easily used by a user by means of generic mechanisms. That is to say that the effort of programming is eliminated and, as a result, this communication can be easily projected by establishing a so-called connection.

Claims

1. A system for communicating between MES (Manufacturing Execution Systems) software applications, comprising:

at least one mechanism of communication;

at least one central processing unit for storing the MES software applications; and

at least one framework program coupling the MES software applications, wherein the MES software applications are mapped to an object model of the framework program, wherein

the mechanism of communication is mapped to the object model of the framework program, wherein

a communication link is set up between two or more objects of the object model by connecting methods of the objects and/or data of the objects and/or the objects themselves, wherein

an exchange of data and/or information and/or events takes place over the communication link, wherein any desired data and/or information and/or events of the MES software applications are exchanged over the communication link independently of the internal format of the respective MES software applications and/or independently of the underlying format of the mechanism of communication, wherein

one mapping of one of the MES software applications to the object model of the framework program is effected by an adapter comprising a tree structure of the objects of the framework program, including components and variables, and which delivers information about the application, data structures of the application, objects for sending, receiving and converting messages to and from the application, a mechanism for performing routing, and a mechanism for logging an exchange of data in the adapter to and from the application and the industrial framework program, wherein others of the adapters and other applications can access objects of said one mapping by means of the object model of the industrial framework program, and wherein the adapter runs in a dedicated process that has no impact on other adapters in case the adapter crashes.

2. A system as claimed in claim 1, wherein the communication link is transparent for a user and/or other systems with respect to the underlying mechanism of communication.

3. A system as claimed in claim 2,wherein the mapping to the object model is effected by an adapter and/or by wrapping.

4. A system as claimed in claim 2, wherein the communication link is set up with a display device having input tools and/or via an autonomously operating program.

5. A system as claimed in claim 1, wherein the mapping to the object model is effected by an adapter and/or by wrapping.

6. A system as claimed in claim 5, wherein the communication link is set up with a display device having input tools and/or via an autonomously operating program.

7. A system as claimed in claim 1, wherein the communication link is set up with a display device having input tools and/or via an autonomously operating program.

8. A system as claimed in claim 1, wherein the communication link is set up between two or more objects by connecting the objects, which are shown in different screen areas of the display device, by a drag &

drop operation with the aid of the input tools.

9. A method for communicating between MES (Manufacturing Execution Systems) software applications, comprising:

providing at least one mechanism of communication;

providing at least one framework program coupling the MES software applications;

storing the MES software applications on at least one central processing unit;

mapping the MES software applications to an object model of the framework program;

mapping the mechanism of communication to the object model of the framework program;

setting up a communication link between two or more objects of the object model by connecting methods of the objects and/or data of the objects and/or the objects themselves; and

providing an exchange of data and/or information and/or events via the communication link, wherein

any desired data and/or information and/or events of the MES software applications are exchanged via the communication link independently of the internal format of the respective MES software applications and/or independently of the underlying format of the mechanism of communication, wherein

one mapping of one of the MES software application to the object model of the framework program is effected by an adapter comprising a tree structure of the objects of the framework program, including components and variables, and which delivers information about the application, data structures of the application, objects for sending, receiving and converting messages to and from the application, a mechanism for performing routing, and a mechanism for logging an exchange of data in the adapter to and from the application and the industrial framework program, wherein others of the adapters and other applications can access objects of said one mapping by means of the object model of the industrial framework program, and wherein the adapter runs in a dedicated process that has no impact on other adapters in case the adapter crashes.

10. A method according to claim 9, wherein the communication link is transparent for a user and/or other systems with respect to the underlying mechanism of communication.

11. A method according to claim 10, wherein the mapping to the object model is effected by an adapter and/or by wrapping.

12. A method according to claim 10, wherein the communication link is set up with a display device by input tools and/or via an autonomously operating program.

13. A method according to claim 9, wherein the mapping to the object model is effected by an adapter and/or by wrapping.

14. A method according to claim 9, wherein the communication link is set up with a display device by input tools and/or via an autonomously operating program.

15. A method according to claim 9, wherein the communication link is set up between two or more objects by connecting the objects, which are shown in different screen areas of the display device, by a drag &

drop operation with the aid of the input tools.

16. A method according to claim 9, wherein the method is implemented by a computer program.

17. A method according to claim 16, wherein the computer program is stored on a data carrier.

18. A method according to claim 16, wherein the computer program is installed on a data processing apparatus.
