Using Quick Data
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.
