Communnicating to a XL10 VAV via WEBs800

[vpnbots]

Hello all,

I'm attempting to communicate and live discover an Honeywell XL10 VAV through a WEBs 8000 running N4.6 . When I enable the local lon device and configure the comm setting for the LON module, and hit discover. I get the following error...

I'm not getting any comm lights on the module. Any ideas on what I might be doing wrong?

When you enable the local device, is the status ok?
What is the status of your lon network?

A lot of the X10 controllers depending on age probably were commissioned with LonSpec. Different domain length ID is something to consider.

Thank you all for the reponses. Turns out all I need to do was reboot the Station and these errors cleared up and I was able to communicate to the controller. Hate when its that easy.
