A Xenta 5/7/9xx controller can either be implemented as
- A Xenta Server, where it doubles as the LonTalk adapter and a Xenta device
- A LON node, where it is a part of an LNS database below a different LonTalk adapter
If the Xenta is a LON node, then it will be represented as a LON device in the network, but also utilizes Xenta Group Bindings to communicate to Xenta programmable controllers (280/300/401). If graphic pages in certain Xenta units aren't displaying data, or connection objects aren't passing data as expected, the online status of the Xenta units should be checked not from the Vista Server, but from inside the Xenta 5/7/9xx. This issue will display red x's on the graphics page.
- Xenta 511, 527, 701, 711, 721, 731, 913
- LNS Database
A Xenta 5/7/9xx LON node pulls "double duty" as both a LON device and a Xenta Lacnet device. It requires one Xenta Group Binding on message tag 0 to facilitate communication with Xenta programmable controllers.
- Log into the web interface for the 5/7/9xx.
- Navigate to Utilities > LacNet > LacNet List Xenta. "LacNet" refers to proprietary Xenta communication.
