Error -200099 DAQmx Create Channel(AI-Voltage-Basic)

[Wladimir Berger]

Hello

if i will run my vi as subvi, it creates an error:

DAQmx Create Channel (AI-Voltage-Basic).vi:5<append>
<B>Task Name: </B>_unnamedTask<A615>

and i get no output data from this vi. If i run the vi only it works well.

Example: I run my mainvi Test_AI.vi and i get no output data. I change to the block diagramm of the mainvi and open the subvi Analog Input multichannel.vi and then i get output data.

Can someone help me? I don't find any thing about this problem 😞

I work with LabVIEW 8.5, NI DAQmx 8.7.1Driver, NI USB 6210

Thanks a lot.

The subVi violates about a half dozen style guide rules and I rewrote it before running the top level. With the rewrite, I had no problems or errors. Try the modified version below and see if you still get an error.

The biggest change was to eliminate every write to a value property node. As you can see, none of them are necessary and the complex sequence structure you had is not at all necessary either.

The same error-200099 even i get when i run VI.

Let me brief my application.

VI should work for 3 devices, namely rack, portable and fylde.

Logic part is ok. when i run the VI i get this error,,,,,,Error i get at Virtual AI channel creation sub VI.

The problem i feel is fylde device is third party DAQ.Though it has got Labview drivers it can't be created/recognised in Virtual AI channel task list.

The Swaping option to pick device and logic to read fylde channels is working, but the problem is at Virtual AI channel creation

Hope you understood the problem. Any suggestions?

Thanks

Why on earth would you expect a third-party device to work the same as an NI device? The channel is created by DAQmx and MAX and that is a utility for NI devices. LabVIEW has nothing to do with it.

Realizing that this thread is really old, I am still hoping someone can help me, because I am having a very similar problem. I have looked at the VIs above and did something quite similar except that I used a loop to add new channels to the task. For some reason I am getting error 200077 (Hardware incapable). I am using an NI 6220 PCI board. Using the DAQ-Assistant, I can configure each AI individually, so that should not be the problem. Any ideas?

Thanks
