I'm trying to implement some state-machine type controls. We are outputting specific voltages at a given time, and need to see if a device triggers only in response to those outputs. Thus, while the output is high we want to check for triggers, and ignore all others.
So...are there any logic devices beyond basic gates in LabVIEW? I tried creating a RS-latch from NANDs, but it complains that there is a circular loop when Q and Q' are fed back to the opposite NAND gate input.
