cRIO and 9205 Calibration

[MichaDu]

Hi,

I'm using a cRIO system with analog input module 9205. To get correct voltage values, I have to read the calibration values. There are examples to do this only in RT VI, but not inside the FPGA VI.

I only want to process data inside the FPGA VI without RT (reading voltage, processing and writing to AO module). Has anybody done this before? Or can I neglect the calibration without getting large error?

If you use the fixed point acquisition then calibration is included in the measurements.

Hi Michael,

thanks for your help!

That means I do not have to take care about any calibration parameters, just read out fixed-point values and work with them?

That would make my application much easier! While I prefer working with physical integer data than fixed-point data, I programmed some module specific VIs to convert FXP-V to I16-mV and FXP-A to I16-µA. This makes it more easy again!

Kind regards
