Instant trending allows you to monitor a variable
tag visually from your CitectSCADA project, without
configuring the tag it as a trend tag. Without the support of the
CitectSCADA Trends Server
to facilitate this functionality, instant trending requires you to
perform the following setup:
Include the
CSV_InstantTrend project. To implement the Instant Trend
feature in one of your own projects, you need to add the
CSV_InstantTrend project as an Included project. (See Including a
project in the current project.)
Enable the
CSV_TrendX events. As described in Running the Computer Setup
Wizard, you need to enable the events CSV_TrendXClient and CSV_TrendXServer for instant trending to work.
Verify that both events are enabled on the Trends Server computer,
and that CSV_TrendXClient is
enabled on any runtime machines that will use instant
trending.
Call the Instant
Trend display. Verify that any buttons or menu items you
configure to launch the Instant Trend display call the function
CSV_TrendX_Display(). call this
function with no arguments set, as this will implement the default
settings. This loads the correct page with appropriate display
settings.
Set the default
display duration. The Instant Trend window only stays open for
a set period of time. Use the [TrendX]Duration parameter to adjust the
default period of time as appropriate.
Configure the
Tag Selection dialog. You can decide whether or not to load a
list of current tags into the Tag Selection dialog when using
instant trending. Having no tags appear in the selection dialog
might be useful if your project has many tags. See the parameter
[TrendX]TagListEnable.
Check the key
sequence used to load tags. You can load tags directly into the
Instant Trend display by putting the mouse cursor on a tag value on
a graphics page and pressing the plus (+) key. However, make sure
that this key sequence does not clash with other application
functionality. To change the key sequence for this feature, see the
parameter[TrendX]KeySeq.
