PROFINET connection could not be established using PROFINET Master Simulator

I have generated a GSD file using the HMS PROFINET GSD Generator Tool. I am able to scan for the device. After generating, I load it into PROFINET Master Simulator tool. I select the correct network interface card and device. After I click start, I can see the correct number of ADI’s but when I click Ok I get the following error message:

The PROFINET connection could not be established: There has been an error on RPC layer:

0x1C010003 - nca_unk_if: The server does not export the requested interface.
Tip: Are you using the right GSD ?!?

What is the Profinet device you are connecting to?

This post solved my issues.

Great - thank you for the update.
