Emergency help, real-time simulation of AMESim and PXI 8881 real-time targets.

[chychy123]

Hi everyone, I am using AMESim with PXI 8881 real-time target for real-time simulation.

Related configuration: AMESim2020.1; PXI 8881 linux RT system, software installed in real-time system are 2021 version.

Currently, I am using AMESim's case file for testing. The documents are as follows, including the relevant annexes.

I followed the steps in the AMESim help document to generate a dll file for real-time simulation, and used WebDAV to place the dll file in the linux ni-rt/startup directory.As shown in the figure below.

Follow the tutorial to create a project file, open the relevant VI, and set the path of file import.

Finally, an error is reported at runtime, and the error message is as follows: The node part of the library function node reports an error.

I don't understand what the reason is, I suspect that it is a path error, but after trying to modify it, it is still the same error.

After carefully reading the help documentation of AMESim, I found that the AMESim case is relatively old, and the real-time system in the case is based on Phar Lap ETS. I am using Linux RT and now suspect that the generated real-time files are not suitable for Linux RT.

AMESim's help documentation is attached and can be viewed directly in the real-time simulation section of the documentation.

The following figure shows the real-time target machine in the case.

Thank you very much for your advice and guidance.

Your suspicion is correct. Linux does not support libraries in the form of DLL. The libraries need to be recompiled as a Shared Library SO. You should reach out to Amesim for the updated documentation.
