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.
