Meter:
Refer to Figure 20. This type of meter
implements a common panel meter-type
display format. The units string is shown on
the face of the meter. All raw parameter
values are interpreted as positive numbers
(i.e. 0...0xFFFF equates to 0...65535
10
.)
Pos/Neg Meter:
Refer to Figure 21. Similar
to the “meter” gauge, this type of meter also
implements a common panel meter-type
display format, but in this instance the
indicated value can be positive or negative
(two’s complement interpretation). In other
words, raw parameter values of 0...0x7FFF
equate to 0...32767
10
, and values of
0x8000...0xFFFF equate to -32768...-1.
Because the meter placard is always
centered around zero, the “Min Value”
attribute is not configurable, and the “Max
Value” attribute is used for both the maximum
positive indicated value as well as the
maximum negative indicated value.
Thermometer:
Refer to Figure 22. This type
of meter implements the universally-
identifiable thermometer display format.
Hovering the mouse pointer over the red
“mercury” portion of the graph pops up a
tooltip which displays the current indicated
value and units.
Line Graph:
Refer to Figure 23. This type of
graph implements a continuously-scrolling
historical data logging line graph. Up to 80
seconds worth of historical data is available.
Hovering the mouse pointer anywhere on the
graph displays a vertical reference line at the
corresponding time, and pops up a tooltip
which displays the current indicated value at
that time.
