NI 4451 with error 10401

[jim_mech]

Hallo there,
I am using the NI 4451 with LV 6.1 and NI DAQ 6.9.3f3
I tried to run the attached VI in order to perform a frequency response but 
I am getting an "error 10401 at AI Clock Config"

I checked the configuration at MAX and the device number assigned there is
the same with the one in the VI.
I have also run the tests of the device and it seems to functions correctly.

I would also like to mention that before the NI DAQ 6.9.3f3 I had NI DAQ 7.4.4
Legacy installed but the VI didn't even load


Thank you in advance for your time!

Hello jim_mech,

I see that you are using a NI 4451 with LV 6.1 and NI DAQ 6.9.3f3 and you are reporting an "error 10401 at AI Clock Config"

Here are some troubleshooting steps:

1) Where you able to run a test panel to test your device? Can you get any readings from your device?
2) You may want to export your task and configurations before you reset the Traditional DAQ. To reset the driver, Select Traditional NI-DAQ (Legacy) Devices under Devices and Interfaces, right click and select Reset driver for Traditional NI DAQ.

You can reference this KB on Why Do I Receive Error -10401 When I Run My LabVIEW Program (Unknown Device Error)?


With regards to why you didn't see the VIs in LV 6.1, with driver versions of 7.4.1 and above LabVIEW 6.1 is no longer supported by these drivers.

Can you give these suggestions and keep me updated with your issue. Have a great day!
