Today, I was trying to help my electrical and software sub teams troubleshoot a simple problem...We aren't seeing any Relay Output LEDs turn on or off on the digital side car.

It started with the compressor not working. Or turning on the Relay Output. Then we just moved to simple logic.

A Button mapped to Relay 2, and a Spike Relay to turn on and off. Software kids downloaded the code, and we don't see the LEDs for the Relay 2 to light up. Which kinda leads like it's a software problem. I looked over the very simple code we have done many many times before Open a Relay Reference to Digital 1, Relay 2, in Open. Then mapped Relay 2 to a button True False to a Spike Relay On or Forward, and we don't even see the LED light up next to Relay 2.

We change EVERYTHING.
CRIO Card
Digital Side Car
Ribbon Cable
Spike Relay (even though we didn't need to because the LED is not coming on)

It seems it's a software problem in the Labview. Anyone else having this problem or tried to get your Relay Outputs to work in 2014 Labview yet?

Are we over looking something simple?

Normally Labview, the Crio, have been pretty rock solid for us and nothing flakey like this.
