Hello Silverio,

thanks a lot for your links. But what I'm looking for is just the
"graphical engine" realizing a block/ports/wires concept. This could be
very general. The code that does real work with the connected blocks is
what I like to add.

This could be IEC like function block application or component based
software in general. Do you know of something like this? What are your
plans for your project?

Peter
