measuring voltage and temperature

[LochiMD]

Hallo,

I've got the problem of measuring voltage and temperature simultaneously, with diferent numbers of samples. I want to use two of the "DAQmx write", but then the error "The ressource is reserved" appears.

Software: Labview 8.2.

Hardware: NI cDAQ - 9172
NI 9211 (Temperaturecard)
NI 9201 (Voltagecard)

How can i fix it?

Hello LochiMD,

there are sereral things you have to care about.

The best would be, you have a look on the following link:

Synchronize continuous Acquisition of Multiple Analog Input Devices

https://decibel.ni.com/content/docs/DOC-12182 (Have a look on the picture, especially left side)

You should use the VI DAQmx Timing (Sample Clock), samples per chanel and sample mode is necessary.

If you do this, your program should work.

Best Regards,

Nina
