Max Value: The gauge’s maximum indicated value. Similar to the Min Value attribute, negative values
can be used if desired. Indicated value characteristics can even be inverted by setting the Max Value
attribute to a value less than the Min Value attribute.
Update Button: Clicking the update button will apply the current configuration attribute settings to the
gauge. Note, however, that simply updating the gauge’s current display properties does not write these
settings to the interface card’s file system. To save the current configuration of all the gauge windows to
the file system, the Dashboard tab’s “submit” button must be selected (refer to section 6.3.5).
Current Value:
The current indicated value of the designated function code is numerically displayed with
the configured Units string at the bottom of each gauge window.
The following is a summary of the different available gauge types:
Gauge: Refer to Figure 27. This type of
meter implements a rotary dial-type display
format. The indicated value and units are
shown numerically on the face of the gauge,
and via the red indicator needle. The yellow
needle shows the previous indicated value,
thereby providing a simple historical
reference. The “Min Value” attribute is not
configurable; this gauge always starts at 0.
BarGraph: Refer to Figure 28. This type of
meter implements a linear bar graph display
format. Hovering the mouse pointer over the
red portion of the graph pops up a tooltip
which displays the current indicated value
and units.
Meter: Refer to Figure 29. 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 function code
values are interpreted as positive numbers
(i.e. 0...0xFFFF equates to 0...65535
10
.)
