How to activate NI switches in parallel

[Ramteke]

Hello,

How do I activate relays on a PXI 1169 (100 SPST) in parallel? Is there any way?

Thanks,

You can place each switch in a while loops (that is, one loop per switch). While loops run parallel in a VI.

Hope that helps.

Hi,

Assuming you are using LabVIEW to program your SCXI-1169, you can modify the shipping example to activate the relays in parallel.  Just as Ali84 mentions you can use while loops to activate the relays in parallel.  If you go to Start >> Programs >> National Instruments >> NI-SWITCH >> Examples >> LabVIEW 8.2 >> niSwitch Controlling and Individual Relay.vi.  This program shows you how to activate an individual relay.  You could modify this program using while loops or flat sequence structures to activate multiple relays in parallel.
