the bits which i supply and which i receive are not the same

[Raghavendra1]

in FPGA target, i created a control for an analog output. and, i connected the same output to an analog input. But when I read this input through an indicator, I saw that the no. of bits I chose in the control and no. of bits in the indicator are not the same, I also used fxp, mathematical adjustments to convert bits to volts, etc. please help me.. I am new to labVIEW.

Can you post your VI.  I'm having trouble understanding your problem.

In your title you say what you send and what you get back are different.  But in the description you say the number of bilts in the control and indicator as different.  If your FXP is set up differently, you will have differences.

If you are outputing an analog voltage and reading that voltage back, you will have noise in the DAC and ADC that will cause errors.  Plus I would expect the output and input to be slightly delayed depending on the sample rate available by the FPGA.
