Weird Case Behavior


Recommended Posts

Posted

All of a sudden I can NOT wire "through" my case statements in my state machine.

I can wire controls that send data out of tunnel nodes. In the same case structure as soon as I try to wire in a error cluster or DAQmx task, then LabVIEW makes a feedback node.

Pretty standard stuff; I feel like I have done many times.

Do I have a weird option flipped?

I have attached screen shots of what I am doing. A 1-2-3

Any help is greatly appreciated.

Ummm, it's called dataflow :) Your subVI has the IO constant as an input (which is an output of the case structure), and the error out (which is an input of the case structure). The case can't execute until it has data at all of its input tunnels, and it can't satisfy that for the error cluster.

Yes, thank you, this was embarrassing.

don't worry ... it doesn't get REALLY embarrassing to till you realize why you violated dataflow while on the phone with NI raving like a lunatic and opening up an SR ... not that I've done that ... :throwpc:
