NI-DAQmx Base Error -200428

[Neil_Helsel]

When trying to run my VI I get this error at every DAQmx:

NIDAQmx base error 200428

The error message then says:

Possible reason(s):

Value passed to the Task/Channels In control is invalid.

The value must refer to a valid task or valid virtual channels.

Task Name: QuickCapture

How do I fix this?

Not much information here. It's dangerous to go alone! Take this.

What other info would help here?

We need information pertaining to your specific subVI and/or task configuration. This error is a generic error that tells you that you didn't write the correct task to the DAQmx input, or your task isn't set up right. Without seeing what you're actally doing with your DAQmx task, that help article is the best advice that can be given when you just give us the error code.

The vi is a subvi to a huge code containing hundreds of subvi's. So would it change anything if I said I only started noticing it when I added an export waveform to excel node?
