AFAIK, "fieldbus" is a bit broader term than just the typical IEC61158-
style remote memory stuff. At least that's the terminology my clients
tend to use (eg. they also call some homebbrewn rs485-based protocols

Maybe it would be better calling it "IEC-61158" instead of "fieldbus" ?

By the way: can this device be opened/used by several processes
simultaniously ?
