Question about a project version

[IAreCBTEF]

Hello ;

I currently have a project file whose OES version is 4.10.3, and the TwinCAT program version is 4022.30,

but the OES version in my computer is 4.10.5 and the TwinCAT version is 4022.27. 

If I want to open this project normally, I need to Does the version have to be the same as the project program version?

Does the OES version just need to be 4.10, or does it have to be exactly the same?

Hellonexidator,

I tested it just now, the project program can be opened normally, And no error is reported after compilation (including library files),

but some library files in TwinCAT3 need to be manually re-added, I don't know why.

Thank you for your answer,

The PLC export from OES should automatically install all required libraries. If there are still some libraries missing after exporting, something is wrong with the project.
