Hi Frank,
Join the club. I used to think the solution to the
problem was to start my own controls company and heck with ITT. One does learn
after 40 years bucking the big boys.
I also like the Emerson dcs.
What can I pass on ? the system will never be any
better than the attention one pays to grounding inside the plant.
Are you using the 3D cad ?

I have been working, 70 hrs last week, on the checkout of a power plant
Distributed Control System. This control system will go on to on a
power plant in Morresville, NC. Things have changed since I last worked
on one of these. The operator stations used to be constructed of
dedicated hardware. Now the operator stations are Del PC's and the
communications is handled with sun servers. The drops in the plant, were the
plant equipment interfaces to the computer system, are now the only dedicated
hardware.
The logical control programming used to involve the writing of scripts,
methods, and codes. A knowledge of UNIX and object oriented
language was required. Now logic blocks (and, or, flip flop,
and sequencers) are picked in an AutoCAD window and pasted into the logic
scheme. With the simulation we have you can see the logic
working. The lines logic activate and turn red. I can
concentrate on the control of the process. I do not have to
speak three letter computerize. The animation of the
graphics still requires codes and scripts. I really like the
Emerson Ovation Distributed Control System. I hate the long hours that I
am working. I also need more money. I can't take it for much
longer.
I had hoped that the fundamental sources of energy would have
progressed this far.
