HI,

The question: is it possible to nest io variables from one fc/fb to lower level fb/fc that is called  from higher level fb/fc.

example:

FB1 has in its io declaration var1

FB2 has in its io declaration var2

Now FB2 is called in FB1 (var2 = var1). I saw this use in FlyingSaw example for Simotion, the real question is: does this work also for FCs?  How many times you may nest this io pointer, from SImatic S7 world this is possible only in certain cirumstances ( I forgot, but I thing it can be nested only with FB and only one level depth), or rather impossible. With some high level language this is possible many times, as it is just passing the pointer of the memory area.

hello my dear friend!

may i have the example of flysaw?

thank you !

It's on DVD with all other examples.
