PID

[Manos]

Hello,
I am trying to test a servo system, using a PID controller and the DAQ
PCI-4451 card. I used the PID Control Loop demo from the Solution Gallery
(LabVIEW 6i ), but I got the error:
" Error - 10403 occured at AI SingleScan.
Possible reasons:
NI-DAQ LV: The specified device does not support the requested action
(the driver recognizes the device, but the action is inappropriate for the
device) "

Is there a bad cooperation between the specific VI and the PCI-4451?
Are there any ideas for bypassing this problem ?

thanks in adcance,
M.

M,

The NI DSA boards do not work with the AI Single Scan VI because it needs a scan rate for the delta-sigma and filters to work correctly.

Here a link to a knowledge base which gives a more detailed answer on this issue:

The Knowledge Base also suggets a programming solution to error as well.
