12.10 Numeric Page
This page displays the process value and
channel descriptor.
The process value (PV) will not be displayed if
the channel is not in a good status. Instead
the text for the channel status is displayed as
one of the following
OFF Channel is turned off
>RANGE Over range
<RANGE Under range
HW_ERROR Hardware error
RANGING Automatic range configuration
(may appear briefly)
OVERFLOW Value out of limits e.g. a maths channel may have returned a bad value
ERROR Error, e.g. a maths channel divided by zero
NO_DATA No data, e.g. nothing has been written to a Modbus input channel.
All channels will be represented in their configured RGB colours. Colour matching will very much depend
on the display the browser is running on.
