Codesys - Profinet Controller / PLC 1.20.4 - Library issue

[ChrisLarkin]

When using Profinet Controller 4.3.1.0 with PLC App 1.20.4 (both latest release) there are many errors cause by unknown type.

At least one library if not more are unable to be resolved causing 502 errors when trying to compile. Find at screenshot of a section of the CodeSys message window.

I have tried the following to no success:

• Create empty project and build only with profinet controller and nothing else
• Uninstall profinet add-on and all dependancies and then reinstall

Hi Chris,

you are using the wrong PROFINET controller (CIFX). Please check the manual we provide!

Okay, I see my mistake, thank you.

Attaching Ethernet then PROFINET to it has resolved my issue.
