If these parameter values are 'off-normal' and you hover over the parameter label on the
faceplate, a tooltip appears to indicate that the parameter is 'off normal.'
Mode is considered 'off-normal' when its value is not equal to the point's NMODE parameter
value.
Mode attribute is considered 'off-normal' when its value is not equal to the point's
NMODATTR parameter value.
Faceplate Control Zone display conventions
This topic describes the display conventions used in the Control Zone of a faceplate.
Inverse video
If the labels adjacent to the
MODE
or
MODE ATTR
boxes are shown in inverse video, it
means that the parameter is abnormal.
If the value in the
PV
box is shown in inverse video, it means that the server cannot
determine the value—perhaps because the server has lost contact with the field device.
If anything is shown in inverse video and you don't why it is occurring, report it to your
supervisor or an experienced colleague.
Red question marks, dashes, or asterisks
If red question marks appear in the
PV
box, it means either:
n
the server cannot determine the value—perhaps because the server has lost contact with
the field device; or
n
the value cannot be displayed—perhaps because the value contains more characters
than the display field can accommodate.
Red dashes indicate that the server cannot find the parameter.
Red asterisks indicate that the display field has been configured incorrectly and requires
attention.
If you see red question marks, dashes, or asterisks and you don't know why it is occurring,
report it to your supervisor or an experienced colleague.
Crosshatch shading
Stale data quality is visualized on displays as a crosshatch shading effect. This visualization
applies to standard HMIWeb alphanumeric, level indicator, and combo box objects.
The default color of the crosshatch is
DarkGray
(
#A9A9A9
). However, it is possible to
define a different color in the
hw-hatch-color
attribute in the display’s cascading style sheet
(CSS). See the topic titled "Predefined style attributes" in the
HMIWeb Display Building
Guide
.
