Tom It's a USB Data Logger (old type of USB). AC powered with battery backup, no taught wires and the logger is housed securely.
Just over an hour has gone by with no more errors, as you say, it may just be the reset/catch up that caused the second issue. I'll have a look again on the morrow to see if the error crops up again. When I first saw the issue, having recently upgraded to 4.8, I reverted to my 4.5.1 back up As the issue was still present I then re-seated the data logger. I'll do the upgrade back to 4.8 once I'm happy the system is stable again. Many thanks.
