KNX/TP: Disconnected
#1
Hi,
We've have a device that has been working fine for years, and now is getting this alerts:
   

When connecting to the bus (through LM) using ETS, and when we read device states, most responses are lost... 
Can it be a SD card issue? Or what can be happening?

Thanks.

It is most likely too big bus traffic.

But when I connect using ETS I can't see a lot of traffic...

What is the bus voltage next to LM? Check the KNX connector.

Not at the moment... When I go again to the installation I'll try and let you know if it's solved or not.
Thanks.
