We’re still having trouble to understand what you mean. The latest firmware for our T3 series controllers is 62.x. Just going from memory we cannot think of any devices that have firmware versions of 5.x
See image for T3-22AI, I just bought 4 more and they have Ver 5.6. Another issue is the Device Instance is not retained on power cycle. We are using the T3 for I/O with ALC controllers, not your controller.
I am not sure what the latest & greatest firmware version is but in general the best bet is to go with the latest version which you can automatically download using the T3000 built in firmware update tool. Losing the Bacnet device instance sounds like an issue from a long ways back. While you’re at it you should also update T3000 itself.
Once you have done that you can show us a few screen shots from the T3000 user interface and perhaps we can pick something up from that. In particular you can pay attention to the network health on IP and RS485 if applicable. If you are still having issues our goto tool is wireshark, you can send on a capture and we’ll look through it for you.
