9144 - Something strange - Timing Out?

[quarterlbr]

Hi-

Don't know if this is where this belongs, but I've got a 9144 connected to a 9074 cRio, and I'm recording temperatures every second on two modules in the 9144 (and others in the 9074). The 9074 has no issues, however, the 9144 seems to want to disconnect or time out, to the point that I had to create a section of code that would reset the 9074/9144 error codes upon every restart. The symptoms are frozen numbers coming from the 9144 (they look as if they are read once on startup, and then stop reading - the readings are frozen after that first snapshot). 9074 numbers continually update, so no effects here. After I connect and "reset" with a manual vi using the 9074 IP address, they "unfreeze".

I've never had this issue before and I've used this same configuration for many more variables than what I am recording now, albeit an earlier version of labview (8.6.1).

Any insight to help an experienced amateur is appreciated.

Thanks.

Try adjusting the scan rate for the 9144 to less then 50 ms. I think back then for older LV versions we can only scan faster then that. To get your data every second you can use a timed loop synchronized to the scan and for period use a 20 to just use every 20th scan.

hope that helps.

Thanks for the suggestion. I haven't tried it yet because it still seems to be working and since we are collecting data, I don't want to stop the test. When I get a chance, I'll play with the scan rate as you suggest to see if that helps.
