Has anyone ever manually programmed a PXI Relay Driver?

[gleen41]

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.

Thanx!

Not sure what you mean by "with a single input" and you have not explained where that PXI module is installed. What's the controller? If you have LabVIEW RT, 5ms should be very easy to do. You could even control your relays with FPGA instead.

Yes, possible, you can define the scan list and send hardware trigger to step through the scan list
