Error 200428 When Creating Task in DAQmx Base

[AliMoradi]

I've written a basic program that captures a voltage signal, plots it, and writes it to a file, but when I run it, I keep getting this error:

"Error -200428 occurred at Value passed to the Task/Channels In control is invalid."

I have attached a copy of my VI. Initially, I did not have the "DAQmx Base Create Task" VI in the block diagram and I was getting the above error. After searching through some documentation, it seemed that the issue was that I needed to put the "Create Task" VI in when using DAQmx Base. Unfortunately when I did that, I still kept getting the same error.

Is there something I am doing wrong here?

Here are my software/hardware information:

Operating Software: Mac OS X 10.11.14

Hardware: NI myDAQ

Software: LabVIEW 15.0 (64-bit)

Drivers: NI DAQmx Base 15, NI VISA 15.5, NI-488.2 15.5, NI-DAQmx for myDAQ on Mac OS X (all for OS X)

Hi,

    Before going for further stpes kindly go through the link https://www.ni.com/en/support/documentation/supplemental/06/learn-10-functions-in-ni-daqmx-and-handl...  to get good knowledge on development of Daq. hope this is helpfull.

The issue is with the input , an invalid input is givin to the daq mx vi. go through the link so that you will be able to solve it.

kudos Welcome 😄

Hi Ali.

You are encountering that error because NI-DAQmx Base does not support the NI-myDAQ device. You do have NI-DAQmx for myDAQ installed, however, which does support that device.

See the instructions here to confirm that the device and driver are communicating correctly:
