Ethernet CompactDAQ chassis is showed disconnected in MAX after manual rebooting

[Ahmed.TUN]

I have a cDAQ 9188 which appear disconnected in MAX after being shut down and powered again.

In fact, after being powered, LabVIEW returns an error when trying to connect to the chassis, and at that moment i noticed that the device is disconnected in MAX.

I get obliged to reset(unreserve/reserve) the device in MAX to back it again connected.

Is there a way to resolve this issue?

Hi Ahmed.TUN,

I'd like to get some more details here.  When you say you have to reset the device in order to get it connected again in MAX, what do you mean?  What steps do you take to do this?  You cannot perform a reset on a device which is not connected in MAX.  Are you saying you reset the device physically a second time to make it show up in MAX?  Can you provide screenshots so we can get a better idea of what you're doing?

What driver version are you using?

Operating System?

How is the cDAQ connected (e.g. directly, through a single router, remote network)?

Have you reproduced this on a second computer?

Additionally, here is a general troubleshooting guide for ethernet cDAQ systems having connection problems:

Hi Ahmed and Chris-

I suspect that Ahmed is experiencing the issue I describe here.  Basically, it seems Ahmed has found experimentally what we intended to be the recommended use case for this functionality, namely that once a connection has been lost for any period of time, a Device Reset or other driver operation on the chassis device is necessary to re-establish proper communication with the modules hosted by that chassis.

Hopefully my comments in that other thread are helpful.
