Loss of signal between SCXI mainframe and vi

[Adzel]

Hello,

I am using a triaxial load cell with the SCXI-1000 mainframe and a SCXI-1321 4-channel module.

I have been utilizing this sytem succesfully for several weeks now. However, as of yesterday the signal seemed to disappear from being passed from the mainframe to the vi. I have done a circuit check and can "see" the signal on the terminals within the SCXI-1321. DAQmx sees the board and mainframe, etc, but no signal is passed thru to the vi.

I stepped away from the laod cell vi I was using and set up a very simple vi with LabVIEW Express. Basically it is the DAQ Assistant and a graph. I set up the channels, etc, very carefully. Still, no signal.

Would any of you chaps have any advice for this conundrum?

Thanks!

I'd like to help, could you post a little more information?
1) SCXI Module are you using? The SCXI-1321 is a terminal block, but what module is it connected to?
2) What DAQ Device are you cabling the SCXI-1000 chassis to?
3) What VI were you using? Was it a shipping example?
4) Are you able to set up a DAQmx Global Channel in MAX and test it there?
5) What version of NI-DAQ do you have?
6) LabVIEW 7.0, right?

Hello,

I think I found the problem...the fuse was blown!!

I replaced it and everything is working properly.

Thanks very much!
