Re: I'm wondering for 3 years why the OPC Foundation didn't works out a new

in 2002 (2001 the betas).

Probably because it took the industry long enough to get together on a 
standard as it was, and they are still developing it as we speak.  There's 
no practical way that process control vendors and users can keep up with 
Mr. (Sir?) Gates and his API du jour; hence the real need for a 
platform-independent standard.

I would prefer a more DCS and OS independent way too.

Please don't mix .NET and OPC-XML. That are technically different
topics. OPC-XML is of course much slower than any other communication.

I'm wondering for 3 years why the OPC Foundation didn't works out a new
standard without DCOM. DCOM is dead since the .NET Framework cames out
in 2002 (2001 the betas).
