I attempted a Lonworks/Tracer Summit integration today, and it failed miserably! I was able to load the Lonworks device into my laptop with LonMaker and see all of the data just fine. We were able to connect the device to the COMM5 port on the Tracer BCU, set it up in the Summit Software, then press the service pin and everything appeared to be rolling along. We set up some AI/AO/BI/BO, we were able to see the point names and SNVT descriptions. Finally, we checked status on the points and they all all read 0, regardless of what the value is. The communications in the summit for the device shows normal. Has anyone dealt with this problem before? Is there something I forgot to do? I can see it using LonMaker, but LonMaker uses LNS and doesn't need the .XIF files, Tracer Summit uses API and needs the .XIF (maybe we have the wrong .xif?). Any insight from a Trane pro would be greatly appreciated.
