Hi,
I have a measurement system thathas been running for some time that, without any apparent change to the hardware or pc that is running it, has begun giving an error: Error -200077.
It running with Labview 8.2.1, cDAQ9172, and a few modules
The full error discription is:
Error -200077 occurred at Property Node DAQmx Timing (arg 5) in DAQmx Timing (Sample Clock).vi:1->Instance 37 3PAI .vi->PAI.vi->wagu.vi
Possible reason(s):
Measurements: Requested value is not a supported value for this property.
Property: SampClk.Rate
You Have Requested: 0.000000
Valid Values Begin with: 22.250739e-309
Valid Values End with: 6.666667e6
Task Name: _unnamedTask<0>
Could it be a hardware failure, or a change to WindowsOS that could cause this?

Probably neither. More likely it is a flaw in your code that is now sending the value of zero to the DAQmx timing property node.

Possibly, but why would it start occuring after happily running for 2 years? Its on startup so its not an unusual path in the program execution.
