The quick
data main form displays groups of Process Tags in the grid and allows
navigation via the tree control. Select the group in the tree to
view it's Process Tags in the grid.
First you must configure
the TagServer that will contain the
Source Tags for Quick Data. Right-click for a popup, use the
"Configure/Tag Server" menu item or click on the TagServer toolbar button to
access the UI for configuring the Source Tags. See the section titled "Using
the Tag Server" for the details of configuring source tags.
Once you have source tags in the Tag Server you
can add Process Tags. Select the "Process Tags" item in the tree
and either add a new tag or a Process Tag Group which can contain any number of
tags. You can also create groups under groups to any depth that
you wish. When you select "Add New Process Tags..." you will be
able to
select multiple source tags from the Tag Server. QD will
create a new Process Tag for each source tag. You may also
select a Source Tag multiple times which will create multiple Process
Tags having the same source.
Add a Process Tag
Group by giving it a name.
Add
Process Tags.
When
creating new process tags browse the available source tags in the Tag
Server and add
them to the "Selected items" section at the bottom of the form.
You may add source tags multiple times to accommodate different
"views" of the device data. Once you press "OK" a Process Tag
for each selected source tag will be created for you with the same default name
as it's source.
View array values
on the main form by clicking on
the array tag in the grid which will display the data in a real-time tooltip.
To disable

tree and the unchecked Enabled column check box in the grid.
Error or

bottom of the form. The three levels of severity
are Error, Warning and Information. The following is an example
output of the QD watchdog detecting an OPC server failure.
