>Also try "http://www.protocol.com":http://www.protocol.com

That site doesn't list anything relevant to the question, and www.protocols.com (note the extra s) limits itself to telecom protocols and networks.

Take a peek at "http://ourworld.cs.com/rahulsebos":http://ourworld.cs.com/rahulsebos which maintains enough links for all mentioned systems for you to be busy for a few days to come!

Greetings,

I believe the Profibus organization website is www.profibus.com
Check there for the several HUNDRED vendors who support DP and PA.
In no way is E-H alone!
