PXI 6229 + LabVIEW

[fgoulao]

Hi all,

I am doing some tests with LabVIEW and I want to send analogic voltage signal to a PXI 6229 (the chassis is a PXIe-1071). I would like to know if I need to add, in the testing programs I have, any control to make the connection between Labview and the controler. For instance, to describe to which connector in the PXI 6229 the cable is connected to (it only has Connector 0 and 1)

Thanks in advance,

Francisco

Fgoulao,

If you take a look at page 20 of the specifications sheet, every pin has a unique name so you do not need to specify which connector it is on.

The actual analog output channels and which connector they are on, are defined by the task you created in MAX, the project, or the VI. Someplace, you have specified ao0, ao1, etc. and the pxi slot number. No other information besides what you already have is required.

I am trying to obtain a simple signal sent from Labview to the controller in an oscilloscope. However he isn't displaying any signal. I am using a DAQ assistant (to generate a signal - analogic (voltage)) and then I select the output which then I connect to the output. In the DAQ data I am simulating a simple triangular signal.

Is it normal that it doesn't work?

That does not make much sense to me. With the DAQ Assistant, the very first thing you do is select the output channel. Please attach an image of the assistant setup and your block diagram.

Hi,

So far, I have made these 2 programs. (attached)

On a first stage I just want to monitor the signal in an osciloscope, but nothing is changing. 

Perhaps, because the programs that I made doesnt make any sense.


Best regards,

Hi again,

Basically I need to drive a nano machining table which is only able to read voltage signal between 0-10V.

Thus, although Labview generates numeric signal, I think it is possible to send a VOLTAGE signal from labview to the nanometric table. I just would like to know how I can do that. 

But, before connecting the software to the nano table, I want to track the signal on an osciloscope.

Thanks in advance, 

Francisco

Please use the proper screen capture instead of using your phone.

I don't see anything obviously wrong. Did you use the DAQmx test panel to generate a signal? What is the physical pin you are connecting to?

[fgoulao]

Hi again.

Thanks everyone for the solutions given. Everything was correctly made, but I was connecting the wrong cable.

I just would like to know another thing: I need to generate a signal using formula block (2 different ones: one with respect to the X axis and the other one with respect to the Y axis). My question is: should I create 2 DAQ Assistants, each one with a different output connected to a different axis, or is there any assembly block that allows me to assemble both formulas block and the connect it (the assemble block) to the "data" part of the DAQ assistant?

Best wishes, 

Francisco
