It runs fine for about 8 days then seems to hang. When it’s hung, you can still ping it. And it has a “heartbeat” but the T3000 software can’t access it. At the bottom of the T3000 screen the message is “No Bacnet “Who is?” command response”. If I power cycle it, it will reboot and run just fine for another week or so. Could my programs be filling up some register causing it to hang? Is there a way to programmatically reboot it once a week? This does not seem to be a hardware issue.

Thanks for the details, it does indeed look like it could be a program or buffer issue of some sort. Could you please email the program to me, we will try to duplicate the issue here. Send to maurice at temcocontrols dot com
