Romilly's HART® and Fieldbus Web Site
Some other HART and Fieldbus web sites
Links to user groups or promoters of the major industrial communication protocols, and to some general survey information. This list is definitely not exhaustive, but will lead you to some interesting sites with plenty more links to other sources.
Links checked 13 November 2004. Please let me know if any of the links don't work! Or if there are good links you think should be added.
