And thanks!

Have you checked out http://sourceforge.net/projects/libnodaveLibnodave just allows you to excnage data with S7/S5 and your computer; therefore the plc must have a program and the data you are trying to work with be coordinated.

Hi mecca.

Go to www.sps-forum.de and ask your questions there.
The original creator of Libnodave hangs around there, and there are several other Libnodave users who would love to help you.
The forum is in german, but just post in english, and they will help you.

edit: Post in the "Hochsprachen & OPC" section.

Thank you for the links BryanG. I am more interested in C++ language, but I will look anyway, for this can help me understand other ways to use libnodave.

vanvanero, the German forum doesn't have an English section as such, but many of the contributors speak good English. Just post your question in the "Simatic" section of the site.

Thank you for the information.
