Issue
See Check Xenta programmable online status from a Xenta 5/7/9xx LON node to determine if the Xenta 5/7/9xx controller is communicating with Xenta programmable controllers on the network. If it's not, graphic pages in certain Xenta units won't display data, or connection objects won't pass data as expected, etc.

- LNS Database
- XBuilder
Cause
A Xenta 5/7/9xx LON node pulls "double duty" as both a LON device and a Xenta device. It requires one Xenta Group Binding on message tag 0 to facilitate communication with Xenta programmable controllers.
Resolution
- Check LacNet status (see Check Xenta programmable online status from a Xenta 5/7/9xx LON node). If controllers are showing an offline status, proceed with the following steps.
- In LonMaker, right-click on the device and go to Properties. View the address table.
- The Xenta 5/7/9xx controller's address table should have the first entry (message tag 0) populated with an index that matches all the Xenta programmable controllers on the network (see Verifying Xenta Group Bindings in an LNS system for more information about checking address table group bindings).
- If the group binding for LacNet communication doesn't exist or is wrong, redo group bindings.
- Ensure the Xenta group masters of the network have not been manually removed from the network pane of the XBuilder project.
- Download the XBuilder project to the device.
- Recommission the device in LonMaker.
- If it is still not communicating, download each of the Xenta units that it is trying to communicate with and recommission them in LonMaker.
