Problem SCANning SCXI-1100

[Peter Kravtsov]

Hello All,

I have a SCXI 1001 chassis with a
2400 module
1200 module
1100 module
I can read all 32 analog signals via 1100 with
SCXI_Single_Chan_Setup, SCXI_Change_Chan and AI_VRead functions.
But when I try to scan them with
SCXI_SCAN_Setup, SCXI_Muxctr_Setup and SCAN_Op functions,
I always get "-10810" status return from SCAN_Op.
I've checked all it's parameters many times, tried to change
some of them - no response.
What is wrong with it ?

Best wishes,
Peter.

Hi Peter,
My NI-DAQ manual gives status codes: 10809 and then skips 10810 and gives
other codes in sequence.
What NI-Daq are you using ? I would like to help.

Thanks and regards

-10810 : internalDriverError
" An unexpected error occurred inside the driver when performing this given
operation."

Latest NI-DAQ.
I think it's version is 6.7.

Peter,
The error code -10810 is 'internal driver error: an unexpected error
occurred inside the driver when performing this given operation.' My guess
is some dll is missing, or perhaps the dll versions for your NIDaq are not
all the same. You might even consider re-installing NIDaq. If that doesn't
work, bug the guys (and gals) at tech support. Bear with them a little though,
not many of their lower level tech people are good with SCXI. (They can
read you what is in the manual, but when it is wrong, they have no clue what
to do).
Now, I use a similar combination to what you have, except I use the 1200
connected directly to a parallel port. Obviously, it sounds like you are
using the 2400 to drive the data to a serial port. If I am correct, you
have to
do the same thing I do. Scan_Op may never work. I have to use Lab_IScan_Op.
Since I don't have an AI or MIO board, the computer essentially negotiates
all commands with the 1200. Lab_IScan_Op is the only function that can do
a multiplexed scan of the 1200 series devices (including the 1200 module).
The 2400 is basically translating the data stream to serial, so it is actually
having no effect on the scan process. If you like, I can show you what function
calls I make. Just let me know...

Virtually yours,
Orlan Franks
