6229

[Jim77215]

My computer is setup with PCI plugin boards for the following NI hardware: PCI-DIO-96 (PN 77738-01), DAQ PCI-6229 PN 779068-01), PCI-1553 (PN PCI301), GPIB (PN 778032-01), RS-422 (PN 778980-01).

I know, that in most cases I can perform self-tests for this hardware using MAX. My question is, can I write my own LabVIEW driver that instructs the NI hardware to perform self-tests and then retreive the pass/fail results?

Hi Jim,

Thank you for posting on NI discussion forums.

Please check the following knowledge base.

Thanks much for the reply. Can I take the "Reset" approach, listed in the knowledge base you referenced, for all of these other NI plug ins as well: PCI-DIO-96 (PN 77738-01), PCI-1553 (PN PCI301), GPIB (PN 778032-01), RS-422 (PN 778980-01).

The reset approach can be used only with DAQmx devices.

You can clear the input and output buffers of GPIB or serial communications if you use the VISA Clear VI.

Please let me know if you have any other questions.

Thanks, we are going to use the Reset approach for our two DAQmx devices.

When you speak of VISA clear do you mean performing that operation is similar to self tests in the same manner that the DAQmx reset verifies self tests.

All what the VISA Clear does is that it clears the input and output buffers. When there's an error when using VISA, you will usually get a timeout error.
