SCXI Strain Null.vi throws -10005 error

[RLD]

I get a -10005 "device is invalid" error when I try to run SCXI Strain Null.vi on a SCXI-1520 which is connected to a PXI-6070E. The PXI is being accessed via RDA/ethernet from a LV7 Windows computer.

Otherwise the SCXI-1520 can be configured and read without difficulty.

Hello,

Thank you for contacting National Instruments.

The 10005 error is usually the result of wiring the wrong device number or incorrect channel SCXI string to the SCXI Strain Null.vi. Ensure that the device number you have connected is the same as the device number that appears in MAX for the RDA DAQ Board that is connected your SCXI chassis. Most importantly, ensure that you have connected the correct SCXI channel string to the SCXI Strain Null.vi. For example, sc1!md1!0 , would null channel 0 of module 1 of chassis 1. Please verify that both the device number and channel string that you have connected are correct.

I understand the usual causes of -10005, but this time things are different. I can read the channel with AI SingleScan or with AI Read, but the same scxi string errors out on SCXI Strain Null.

The only thing that might be unusual is the remote computer is a PXI-8146.

Also I have not setup any virtual channel or DAQmx Task. Am only using the scxi string.

RLD,

You may want to try running the SCXI Strain Null.vi locally on the machine itself rather than through RDA. This will allow us to determine if the problem is local to the PXI-8146 or if it is being caused by a RDA Server communication breakdown.
