Components Compiler Error (PLCNEXT0001): The program name '...' conflicts with a program organization unit with the same name.

An included library contains a non-IEC 61131-3 program which has the same name as a local POU in your project.

Remedy

In the COMPONENTS area, open the folder 'Programming | Local' and locate the user-defined POU with the duplicated name. Rename the POU. After renaming the POU, some further adaptions may be necessary (e.g. its instance calls).
Or
Contact the provider of the library.
If the library source code is available and can be edited, modify the program name and release the library again.
