LabVIEW control TTI PL303-P power supply

[GerdW]

Hi Evans,

Could you show me a sample vi to control PL303-P current?

No, I can't.

There should be one in the LabVIEW driver for your device.

If there is no such VI: read the programming manual of your device, create a copy of a similar VI of the driver and adapt it according to the commands of your manual. (That's the usual way to extend such device drivers.)

I downloaded official PL303-P vi examples. Why am I facing these errors?

Attached is PL303-P vi errors screenshot.

Hi Evans,

Why am I facing these errors?

Don't know. You should just check one of those subVIs!

When you mark one of the subVIs in the error list you should get the details of the error in the subVI. Unfortunately you didn't do this before creatingyour screenshot…

Did you install the device driver as intended (in the correct folder)?

Default directory.

C:\Program Files\IVI Foundation\VISA\Win64\PLP\

C:\Program Files\National Instruments\

Hi Evans,

the DLL is missing or not within the search path for DLLs…

(Or you are using a 64bit version of LabVIEW trying to call a 32bit DLL…)

How do I resolve this?

[GerdW]

Hi Evans,

use the 32bit version of LabVIEW to interact with 32bit DLLs…

Are you using LabVIEW-64bit? If yes: why? Is there a specific reason?

[EvansL]

Yes, I am using LabVIEW 64 bits. No specific reason. The LabVIEW download link was 64 bits.

Is downloading LabVIEW 32 bits the only way to resolve the issue?

Hi Evans,

according to Microsoft it's the most easiest way…

Hi Evans,

Can you share with me the vi samples?

I cant get my PL303 to work either.

Thanks.
