There are several vendors of comercial products.
Examples:
www.deltalogic.de
www.mhj-software.com
www.process-informatik.de
www.traeger.de

And then there is Libnodave which is an open source project:
libnodave.sourceforge.net/index.php

good luck.

thank you jesperMP

but can you send me english or french links?

and if it's possible I search non commercial solutions.

thanks

Some of these web-pages, not all though, have english sections (if you look closely).

The libnodave project is the only non-comercial solution I know of.
