Are dlls compatible with the compact rio?

[flip518]

I would like to use the instrument drivers for a Chroma 63201 electronic load on my 9014 model compact rio.

I tried to load them and recieved this error message:

Failed to download chr6320x IVI Error Converter.vi
LabVIEW:  Failed to load shared library chr6320x_32.dll:chr6320x_GetError:C on RT target device.
Deployment completed with errors

Is it possible to load a dll on the rio, or do I need to write my own drivers which are compatible with the rio.

Thanks much, 

Phil

I don't think you would be able to run the DLL on the RTOS. What exactly are you trying to do? How are you communicating with the device?

Hi Adnan,

Thanks for the input.  I am communicating to the device with the rs 232 port on the compact rio.  I can alternatively just use the rs 232 command set provided with the Chroma load, I was hoping though that I could make use of the instrument drivers to save some development time.

You just need to be sure if the DLL has been compiled for the Real Time OS. Otherwise, it wouldn't work.

Hello,

The reason is that the VxWorks RTOS on the 9014 requires libraries to be .out format rather than .dll. See this KB:
