Want to write to a digital line based on analog trigger

[DeniseN]

Hello!

I'm monitoring a voltage channel, and would like to send a digital signal (on another channel) when the voltage channel changes. Would the VI I've attached work? Is there a way for me to simultaneously read the digital lines to determine when the digital signal was sent? Ideally I would be able to record this timing data in the same file created from the analog data; can I do this?

I'm using DAQmx 7.4, Labview 7.0, and two PXI-6133 cards.

Thank you,
Denise Nelson

Hello Denise. Thank you for contacting National Instruments. The PXI-6133 does not support digital triggering on a digital line. Only our PCI/PXI 653x cards support that. Therefore this program will give you errors. Please let me know if you have any questions. Have a great day!

Ah. Thanks!

I'm doing something similar however I need to read a digital signal based on an analog trigger.
See attached VI.

Do the PXI-6133 cards support that capability?
