15.7 Linking to EMB HubLite Device Status Pages

It may be helpful to create a shortcut or a hyperlink on another web page that will direct the browser to bring
up a speciﬁc device status page in your browser. To do this, right click on the page and select properties.
The URL for the page will be shown on that dialog. Simply copy/paste this URL into your link.

The EMB HubLite can provide Modbus device data in XML format. This feature, coupled with browser
based AJAX (Javascript) can provide a very powerful tool to allow the creation of custom web pages.
Further examples of XML and its uses are available on the Leviton website in the
Documentation/Technotes section.
