Version Control for PLC Code

[cadomanis]

I am wondering if there is anyone using a version control system with their PLC programs. We are constantly working on developemnt for the same couple of basic programs, and desperately need a better way to track when, who, and what was changed in a given version of the same basic program. Any thoughts? Chuck

At work I use SourceSafe, which comes along with Microsoft Developer Studio. You can also try Subversion (http://subversion.tigris.org). It's open source and they have recently release version 1. I had a little experience using it, it has some nice features, and there's a tool TortoiseSVN, which will integrate Subversion into Windows Explorer. But the administration can be a little difficult. Hope this helped.

For Omron PLCs, I believe some kind of file management system is included in one of the future releases of CX-One. Don't have any details though. I must say since the CJ/CS CPUs latest version can store also symbol lists, section names, rung names & comments it has become much less of a problem when having the wrong version of program to work with.

Individual PLC vendors do try to provide some rudimentary version management, but it is by necessity more of a test and development tool. The bigger issue for operating process and discrete manufacturing is maintaining version control across multiple platforms and software versions that is consistent, simple and similar. If you ever need info on version control / change management, I can help - it's what I do for a living.... http://wingtipllc.com/PLC-Version-Control.html David Edited June 26, 2007 by David McKay
