Config MAX to simulate Power Supply

[ale_m]

Hello,

I have installed Measurement and Automation Explorer, and I have no phisical NI hardware connected to my PC.

So, I'm trying to use the posibility to simulate a hardware using Measurement and Automation Explorer.

I want to simulate an interaction with a Power Supply.

So in MAX, under IVI Drivers, I've created a Driver Session configured like this:

Simulate with nisDCPwr

Driver Setup Model:41-111-111; <-- I've set this random value

The only Software Module available is pi40iv, with Module Path pi40iv32.dll, and Published API IviDCPwr 1.0

I haven't set any Hardware assets.

So I'm using VC++ to acces a power supply. I found some exemples, and I tried this:

optionString = "Simulate=1,DriverSetup=Model:41-111-111;";

sResName = "PXI4::15::INSTR";

viCheckErr(IviDCPwr_InitWithOptions(rsrcName, VI_TRUE, VI_TRUE,optionString, &vi1));

And it outputs this error:

"The session name or logical name could not be resolved to a session or driver session."

I really have no ideea how to configure MAX in order to be able to simulate a Power Supply.

Is it possible?

Can anyone help?

Thank you,

Alexandra

ale_m,

If you install the NI-DCPower 1.2.2 driver, you can create a simulated power supply just like you would with any other DAQ device.  Then, you can make the appropriate DCPower calls in C++ to access the simulated device.

You can download the latest driver here: NI-DCPower 1.2.2

This Developer Zone article explains how to create a simulate device: NI-DAQmx Simulated Device
