Off”. Strong color conventions unclutter graphics by needing
less explanatory text, for example; a yellow filter may be
clean, a red filter dirty, and a red and blinking filter dirty and
unacknowledged.
Buildings, ducts and piping, valves and dampers, floor plans,
and most text on graphics are typically static.
Graphics consist of artwork, text, and dynamic points with
no positioning restrictions for any element. Dynamic points
are typically presented as text in a box; such as 72.9 or Off.
The displayed text changes dynamically as the point status or
value changes. Displayed status and point values are
periodically updated or may be manually updated at anytime.
Dynamic points may be presented symbolically as the pumps
are in Figure 7. When presented symbolically, dynamic point
status and condition are indicated by colors.
Controller Support
A major portion of the BMS Software is the definition and
maintenance of system-level controller software. The software
allows viewing and editing setpoints and parameters, up or
down loading controller databases, adding and editing points
and programs, and executing diagnostics.
OPERATION
Operator access to the system is usually positioning the
cursor (via a mouse) on a graphic display of a system.
Following are examples of BMCS automation concepts for a
two building facility with boilers, chillers, and VAV air
handlers. When an authorized operator signs on to a system
PC, the system recognizes the access authority and presents
the top level graphic (Fig. 5)
