DataSocket servers, Lookout or LabVIEW DSC module applications,
and data published by the Data Publishing VIs.
DataSocket uses uniform resource locators (URLs) to specify absolute
paths to data items. A URL consists of three separate components:
protocol, network address, and locator. You are probably most familiar with
URLs from using a Web browser. For example,
http://www.ni.com/
support/fieldpoint
is a URL in which
http
is the protocol,
www.ni.com
is the network address, and
support/fieldpoint
is
the locator.
The FieldPoint software package installs a DataSocket URL browser in
LabVIEW. To launch the browser, select
Tools»Browse Network for
DataSocket URLs
. Enter the IP address of the FieldPoint device or
computer you want to browse, and click
Refresh
. After a short pause,
the available DataSocket servers appear in the window. Open each server to
access an item on that server, as shown in the following figure. Once an
item has been highlighted, its URL is displayed in the URL field. You can
use copy <Ctrl-C> and paste <Ctrl-V> to insert the URLs into the
DataSocket read and write VIs.
