["Scharf, Michael (Nokia - DE/Stuttgart)" <[e-mail]>]

Your proposed wording would help.

BTW, according to section 5.5, the "CNC" may also be embedded inside a PNC. This "controller-in-controller" embedding could perhaps also be mentioned earlier in the document, e.g., as part of your proposed text. It could be something like: "For example, the CNC may in fact be a controller or part of a controller in the customer's domain".

Anyway, I was just wondering if terminology other than the generic "controller" could perhaps better distinguish the different functionality. I won't insist on any change.
