Calculate RPM using proximity sensor with Digital Input Module NI 9422

[SultanUsman]

Hello!

I am trying to calculate Motor RPM using the digital Input module NI 9422 in LabVIEW FPGA (cRIO-9063). I have designed the counter that counts the digital pulses, but I am confused about how these pulses convert to RPM value. Please find an attached image of my codes and let me know which part needs to update, also share your code if possible.

Kindly help me to fix this error.

I am a beginner in LabVIEW.

Thanks & Best Regards
