I worked at Foxboro as the architecture for I/A was being researched. For many years, I have been following the architectures of the various DCS as they have been released. From the beginning, I/A was designed to use as much open technology as possible so that it could keep up with the rapid evolution of microprocessors and software technology. The foundation of I/A from the beginning was the use of Intel x86 family of microprocessors, Unix as the Operating System, and Ethernet to exchange data wherever it was permitted.

The I/A Series system is now a very well proven system that has evolved as designed over two decades by using the foundation technologies. Recently the I/A Series system has been incorporated into InFusion ECS, the latest product from Invensys. InFusion features significant levels of pre-integrated software and systems from both Invensys and its partners. This can significantly reduce the cost of expansion while increasing the scope of application.

Although I no longer work at Foxboro, as an industry consultant it is my job to keep up with DCS technology. The most important factor in determination if a DCS has become obsolete is to examine the architecture. I/A architecture is the same now as when it was released more than 20 years ago, but the open elements of I/A: the microprocessor, the operating system, and the communications network (data Highway) have been able to adopt all of the new technologies as they have become available without requiring any changes in the design of I/A.

If anyone asks, I have equally good things to say about most of the other DCSs supplied by the other major suppliers.

Mr. Caro,

Refer to your reply, May I ask you to give the factors which are important to evaluate the different DCS brands/supplied DCS systems?
I am involved in evaluation a supplier and I wonder if you could guide me on this issue?

Thank you

Hello,

I/A V8.5 is the Day0 installation for XP workstations working on windows. The earlier day0 installation for windows is I/A V8.2. It is always recommended to go for the latest version.

FYI - I/A V8.3 is the Day0 installation for Solaris based stations on the MESH.

This thread turning to be very interesting and informative.

Seniors and experts are welcome to drop their comments as the thread goes down...

Share your experience and ideas, and technical advice that will help freshers like me. and others.

God Bless you All.
