Hi, I'm trying to connect my S7-1500 to WinCC OA by following these steps:

1. Save export_V20 to the path:
   winccoa_path/data/clsetup.
2. Export the project from TIA Portal V20 and save it under:
   winccoa_Project/data/TIA_Projects.
3. Create a connection using the TIA project.

The setup was successful, but the host state enters a loop of connecting and disconnected. This indicates that I'm unable to establish a stable connection with the PLC.
However, I can still connect to the PLC normally from TIA Portal V20.

What could be the problem?

Thank you, it worked. I set the wrong adapter
