PXI 8108 lose Ethernet connection

[razvancrt]

Hello everyone,

I have a small issue regarding  the controller PXI 8108.

After a certain amount of time ( few hours/days), the Ethernet connection between the PC and the  controller PXI 8108 (used as Remote System) is lost.

The connection will be possible only after restarting the chassis

The controller has no fault present. And the link led of the Ethernet is on.

I have noticed this issue on 3 systems with similar configuration until now.

Any tips?

Thank you!

System Info:

PXI 1044 Chassis

PXI 8108

Firmware version: 13.1

OS: NI Real Time Phar Lap ETS 13.1

Hi, I have the same issue with a 8104 PharLap controller and LabVIEW 2013 sp1.

Have you solved? How?

Many thanks.

Hi,

Unfortunately, I haven't found any solution yet.

The good think in my case is that the tests in automatic mode are not used very often, so the issue is not blocking yet, it is just annoying.

Maybe you can get in contact with NI support.

Currently I have no time to spend with an issue that is not blocking 🙂

Thanks for your reply.

I think that the issue could be related with the low-priority loop factory setting for the TCP/IP stack.

I am planning to log CPU RAM and TCP connection before calling NI Support.

Anyway if I'll have news I'll post them.
