Hello, I'm having a hard time with my code snippet that I've used to write digital values to a port. Essentially my program has three error conditions that are supposed to trip a relay in an SXCI-1160. I've written to port on newer items like cDaq and I have a working example of using it on an SCXI-1160 but for some reason I can't get it to respond here. I can put a probe on the line going into the code, but it doesn't appear that any combination of numbers causes anything to happen on the hardware. Am I missing something? The RB 16ch simple drive.vi is what I'm trying to use as a subvi since it's an 1160. I pulled some parts out and made an independent sample code in write to 1160 task.vi, which uses the config.vi as a subvi. Thanks in advance. I've gotten arond it by using some case structures and Switch VI's, but it's much less efficient than Write To Port.

This is Labvew 2013 at the moment.

It's writing to digital port 0 of an SCXI-1160. I expect the integers to change the states of relays like they do on our other system.

So this architecture has worked on other NI switch modules? How are you mapping the integer values to specific relays?
