How can I monitor the DIO Buffer in non regeneration mode

[Steve_Block]

I have an application where I'm feeding samples into a USB 6341 devices in non regeneration mode and want to know how to monitor how many samples remain in the buffer until it runs out. Is there a way to monitor this?

Have a look at the "Status" properties in a DAQmx Write property node.   There's one called "Space available in buffer."   Subtract that from the buffer size to see how close the buffer is to running out of fresh samples.

Where do I find that?

In the DAQmx palette, pick the icon labelled "Write Node".  Once it's on your block diagram, the drop-down menu will let you pick "Status" and show the sub-menu where you can pick "Space Available in Buffer".
