LabVIEW
Passing Logic Through Blocks
This is a LabVIEW forum and we don't even know what you mean by words like "block", "gate", etc. These are typically not a programming terms. If you talk about a green wire, do you mean a boolean on the block diagram or something physical? Are you talking about an error wire?
In summary, be specific and try to avoid ambiguous words. Seeing some code always helps!
How are things connected? How much current do these devices draw and how much do you provide?
Best guess is what you're talking about is somewhere inside of this code? Since that's the part that leads to a "DAQmx Write"?
If so, then your biggest problem there is the absolute mess of wires you have there. Clean all of that up so you can actually see what leads to where and I bet your problem becomes more apparent.
I would also advise getting rid of those Boolean constants you have going into logic gates because they're silly. For instance, in the middle there you have a True wired into an And node... which you can just replace with a straight wire.

One quick question. Are your indicators lighting up on screen? If not then I recommend starting at the indicator and working backward with probes until you find the culprit. If the indicators are coming on then your task could be set up wrong, your wiring could be wrong, or you could have a bad card or relays.

The constants are necessary for for the system being controlled.
The constants do nothing TRUE AND TRUE/FALSE will always be the value of TRUE/FALSE. FALSE OR TRUE/FALSE will always be the value of TRUE/FALSE. Aside from that, have you done anything the check your logic? Are you familiar with probes? They are very convenient for this kind of thing. Follow the logic back to see where the problem is located. Make sure that what you are sending to the DO is correct. You have not said what the data going into the DO needs to look like, nor have you attached a vi that we can run. A picture is worth a thousand words, but a vi is worth 10,000 pictures.
