Our toolkit SP7 makes it easy to communicate with a Siemens S7 PLC.

Is there a free version of the package?

How many hours can you spend in trying to make things work for $250? Where I work that is about 2-3 hours of work!

Hasn't prevented me from creating my own Siemens S7 Toolkit for internal use  but I couldn't possibly make it available for that price.

Thanks a lot for that answer!

And sorry, that toolkit is not available for free. We've invested quite a lot of time to get it to a point so that it is easy to use for LabVIEW users.
