You can imbed an FB in another by declaring it in the STAT's.

That way the imbedded FB's IDB will be part of the called FB.

any orientation is good for me

This is extremely easy.

In the declaration part of the FB, where you would normally specify a BOOL or an INT type, you simple write the FB number ("FB123" for example) or use the symbolic name of the FB ("my_special_FB" for example).
Only prerequisite is that the FB you are calling must be defined first.
