I use Labview2020 Daqmx examples analogue input, voltage continuous input.
But there is wrong when I run the program.
The error is I can't read the name of the device.
My device name is NI Compactrio chassis(NI-9040) and NI-9205 modules. I use ai0 for my physical channel, and there is no other channel used.
How can I run this program correctly?
Solved! Go to Solution.

When you run that VI on your Windows computer then this computer doesn't know about the NI9205 module in your cRIO target!
The cRIO is a computer of its own, and so you have to run that VI on the cRIO! (The cRIO904x devices also support DAQmx…)
I recommend to read the "Getting started" for your cRIO as well as its manual!

Hi, GerdW
Greatly thank for your information.
I followed the instruction but there is a problem when I create my channel
for NI 9205, Why?
How can I solve this problem.
Thank you.

Hi AaBb,
even though I cannot read Chinese I guess I saw the problem…
As I wrote in my last message the NI9205 module is maintained by the cRIO target!
You still try to create a DAQmx channel in your "my computer" host part of the project, but you need to create that DAQmx task/channel in the cRIO RT target!
I repeat: the cRIO is a computer of its own and manages its own resources!

Problem perfectly solved!
Greatly appreciated GerdW's help. (love you, GerdW!)
There are three bugs I met:
1. Please create a data reading project under the CRIO system(CRIO is the host computer)
2. Please install and activate your Real-Time driver(from NI.com) on your host computer.
3. Please check the language of the CRIO terminal and your host computer(both English or both Chinese, it must be the same)
thank you all! Hope it helps you.
