I recently installed a couple of new ABB drives with the FLON Lon interface card in them. I can bring them in to LonMaker using the supplied XIF file with no problem.
The problem I'm having is using the XIF file to create an lnml file in AX using the Lon XML tool. When I run the tool, it locks up AX. I've used the tool many times before and never had this problem. I don't get any messages, AX just quits responding and CPU usage goes to 50% and stays there.
I thought at first that it might be because the FLON card has 140+ variables available on it, but I ran the Lon XML tool on a NexLite XIF file with over 800 valiables and that worked just fine.
I'm running a Softjace on 3.1.30 and haven't run into any other issues that I've felt a need to upgrade.
