C# IIviDCPwr . How to track compliance message (QueryInCompliance)?

[PeterSevos]

Good day.

Would you please help me with tracking compliance message (overvoltage error) with my PXI-4112?

"Outputs["0"].QueryState(OutputState.OverVoltage)" doesn't work. It works only with OVPEnabled on and doesn't supported with 4112.

In classic NI-DCPower it used to use "Measurement.QueryInCompliance(ChannelName)" and it's work great, bool value is always available! But in current project I should use IVI wrapper.

So, is any idea to call function like "QueryInCompliance" using IIviDCPwr?

Hi PeterSevos,

I was able to pull up the current NI DC Power Supplies and SMUs Help and found we have the function 'niDCPower_QueryInCompliance' available and it sounds like the VI you were using before. I have attached the help page for this function below.

The right answer is to use "QueryState(OutputState.ConstantCurrent)".

Thank to all!
