DLL-file deployment to CompactRIO using LabView

[esplu88]

hi,

I have compiled a DLL-file from SimulationX, and I want to deploy that file to a CompactRIO using LabView. How do I do that?

thanks in advance

What do you mean by deploy?

[Akiel]

Ive taken it to mean install and use in a labview enviroment, as you can deploy a software package, pity i have no experience of compact rios

with deploy I mean running the DLL-file on the compactRIO. Anyhow, I found a good guide on ITI.com that solved the problem 🙂 

thanks for the reply!

You can't deploy a Windows DLL to Compact RIO. While newer Compact RIO systems do use a x86 compatible CPU, they still run VxWorks which is TOTALLY incompatible to Windows in any way you can think off. For the VxWorks application on the CompactRIO, a DLL is just a binary file of gibberish. Shared Libraries for CompactRIO need to be compiled as ELF shared libraries using the VxWorks toolchain (a GCC based toolchain) so your source code for the DLL better is in C/C++.

One correction, the cRIO 900x and 908x seem to use a x86 CPU and run Pharlap ETS. Pharlap ETS allows to run SOME Windows DLLs but by far not all, since it only supports a subset of the Windows API as available at around Windows 2000. So if you have a cRIO 908x controller (900x are very old and unlikely to be used nowadays)  you MAY be able to deploy the DLL to your cRIO system. To make sure you need to check the DLL for unsupported API imports by the DLL checker that can be downloaded for your specific LabVIEW version here.

About that DLL-file, SimulationX seems to be producing windowsplatform-dependant c-code, so I dont think it's possible to compile an .out file from the c-code generated from simx. I think the solution is to, as you said, use cRIOs with Phar Lap OS.

thank you for the reply:)
