I've put some diagrams from the forthcoming new edition of my HART Technical Overview booklet at www.romilly.co.uk/hartstructure.doc . It's a three-page Word document. Hope it helps ...(If anyone wants to know when the new edition is available - but not free, I'm afraid - just email me with subject "new booklet" and I'll be sure to let you know.)
