Abstract

The invention relates to a method for remote-control programming and to a machine control system 2 for performing the method. To refine the method so as to simplify and shorten an execution operation of a control program source yet automatically avoid version conflicts between the control program source and the compilate in the machine control system, it is proposed that the program source 3a stored in memory in the machine control system be executed by means of a programming device 1, and after the execution, the compilate of the executed program source is generated and stored in memory in the machine control system, where it is made available to a control module.

Claims

1. A method for remote-control programming, wherein a programming device (1) communicates temporarily, in particular during maintenance or upon startup, with a machine control system (2), and in the programming device (1), an execution of the control program takes place, whose program source (3a) and whose compilate (4) are stored in memory in the machine control system (2), and there is a programming module (5b) in the programming device (1) by means of which the program source (3a) stored in memory in the machine control system (2) is executed in the programming device (1), and after the execution, the compilate (4) of the executed program source (3a) is generated and stored in memory in the machine control system (2), where it is furnished for a control module (6).

2. The method of claim 1, characterized in that the program source (3a) is additionally stored in memory in the programming device (1);

and that before and/or after the execution, a comparison for matching of the program sources (3a, 3b) of the machine control system (2) and the programming device (1) is done.

3. The method of claim 1 or 2, characterized in that during the communication and/or during the execution of the program source (3a), access to the program source (3a) of the machine control system (2) is prevented.

4. The method of claim 3, characterized in that during the communication and/or during the execution of the program source (3a), a flag of the machine control system (2) is set, which deactivates the capability of access to the program source (3a) of the machine control system (2).

5. The method of one of claims 1-4, characterized in that a direct physical communication connection (8) between the programming device (1) and the machine control system (2) is employed.

6. The method of claim 5, characterized in that the communication is effected via a direct ethernet interface (9) between the programming device (1) and the machine control system (2).

7. The method of one of claims 1-4, characterized in that the communication is effected via an existing communications network (10) of machine control systems (2), into which network the programming device (1) is incorporated, and the programming device (1) selectively accesses an individual machine control system (2) via the communications network (10).

8. The method of one of claims 1-7, characterized in that the communication and/or the execution is displayed at the machine control system (2), for instance via a communication/execution display (15) of the operation and visualization module (7).

9. The method of claim 8, characterized in that there is a programming barrier in the machine control system (2), which is lifted by means of a confirmation entry.

10. The method of one of claims 1-9, characterized in that the execution of the control program is enabled by an access security, activated in the machine control system (2), for only predetermined users.

11. The method of claim 10, characterized in that an enabled access to the machine control system (2) and/or a denied access to the programming device (1) is equally effective.

12. The method of claim 10 or 11, characterized in that an addressable remote readiness switch (14) that can be spoken to is provided in the machine control system (2) and is locked via the access security.

13. A machine control system, in particular for performing the method of claim 6, characterized in that the machine control system is incorporated, via a communications network interface (11), into a communications network (10) of machine control systems (2) and has an additional individual-connection network interface (9), which is to be connected to a corresponding interface (12) of the programming device (1), as a result of which the communication with the programming device (1) takes place.
