I had this idea that it would be really nice to be able to program the relay card to open and close certain relays with a single input, instead of controlling a single relay with a bunch of labview code and have my timing be limited to software constraints.
I want to be able to turn on 4 relays, sequentially, within 5ms. I don't think I could do this with software because it would take to long for the computer to make it happen. But if i could make it a hardware timed event, that would be really cool.
Theoretically it would make sense that i would be able to program the relay card, but i have no idea how or where to begin.
The relay card I am using is a NI PXI-2567.
You may be able to load in a scan list and then use a counter to clock the advancement of the scan list. I am not certain if your board can do that, but that would be the way to do what yo are asking.
