-------------------------------------------------------------
The DWP demo was written using specifications and schematics from the Los
Angeles Department of Water and Power. The specifications required that a
schematic be displayed with the following features:
First, when the control valve is picked a new window with the Hand/Autostation
appears. This window contains the controls for setting the control valve.
When the values are adjusted to the user's satisfaction the Confirm button
causes the values to be read by the program and the control valve rotates to
reflect its status. Each of the four control valves in the demo behaves the
same way. When the valve is open the pipes show flow and the pressure drums
indicate fill level. The data controlling fill level is simulated with a
Function Data Source created in DV-Draw.
Both the High Pressure Drum and the Low Pressure Drum can be picked by the
user to display a new window with more detailed information.
To keep the screen from getting too cluttered a button to erase and add
details was added, and the Ammonia Subsystem was put into another window.
For ease of use, buttons bring up a Help window and a Legend window. To see
how to operate this demo, read the Help window. To get a description of the
symbols used in the schematic, read the Legend window.
