How to read 2 Counts Inputs with 9178?

[Giuliano06]

Good afternoon everyone!
I need to make a program to read the frequency of 2 encoders and read 3 temperatures.
From these frequencies, I will be able to calculate the speed of the wheels.
When I try to create this task, LabVIEW shows the following errors:

- You can not create two Counts Inputs for the same task.
- When you change the option to "Large range for 2 counters," the program reads one value and then locks.

I tried to create an independent clock for the second frequency signal but did not succeed as well.
Someone would have an idea how to solve this?

Currently I use a cDAQ 9178, to measure the frequency use to 9402 and 9213 to measure temperature.

Thanks guys.

Please include a Snippet of your code, or attach your VIs, so that we can better assist you. It helps to see the code that you've tried that throws the error.

This document might help you figure out how to configure your counter task.

My VI is attached now. 🙂

What happens if you put Low Frequency with 1 Counter instead of 2 counter?
