Abstract

A method and system for generating programming code and/or configuration data for programmable controller and the networks on which they operate is disclosed. In one embodiment, programming code is generated on a centralized server having a web-enabled engineering tool. The engineering tool operates on client devices that are in communication with the server over a network, such as the Internet. Preferably, the engineering tool runs in a browser application (or other network-interfacing-application) on the client device and a user generates the programming code on the server with the aid of the client device. By centralizing the engineering tool, which may contain a configuration editor and a configuration management tool having version management functionality, a new business paradigm for providing engineering tool services to customers having programmable controllers. In addition, new methods and tools for collaborative engineering of programming code are enabled.

Claims

1. A system for configuring I/O networks and devices comprising:

a server communicatively coupled to a network; and

a configuration editor residing on the server, the configuration editor adapted to be invokable by a client device that is communicatively coupled to the network.

2. The system of claim 1, wherein the network is the Internet.

3. The system of claim 2, further comprising a tool for developing programming code for a programmable controller.

4. The system of claim 1, wherein the client device comprises a personal computer.

5. The system of claim 1, wherein the client device comprises a PDA.

6. The system of claim 1, wherein the client device comprises a cellular telephone.

7. The system of claim 1, further comprising a version management tool that resides on the server.

8. The system of claim 7, wherein the version management tool is part of a configuration manager.

9. The system of claim 1, further comprising a version management system for managing versions of a program for a programmable controller, the server having the version management tool installed thereon, the version management tool invokable by the client device over the network, and a plurality of versions of the program residing on the server.

10. The system of claim 9, wherein the version management tool is part of a configuration manager that resides on the server.

11. The system of claim 9, wherein the version management tool comprises an application for searching for versions having predetermined attributes.

12. The system of claim 9, wherein the version management tool comprises an application for comparing two or more versions with each other to show differences between the two or more versions.

13. The system of claim 9, further comprising an engineering tool residing on the server, the engineering tool configured to run on the client device in a network-interfacing-application.

14. The system of claim 13, wherein the network-interfacing-application comprises a web-browser and the network is the Internet.
