Why does an EF block have a "Different Code Object" if the version is remaining the same in the Types Library Manager?

Issue:
When opening an archived Unity Pro project with a recent version of Control Expert, Library Version Management is launched, comparing the types in the library and the ones in the project.

Even if the version of some EFs is remaining the same one, there is a "Different Code Object" in the type. This is caused by an internal change done on the system services provided by the PLC, which generates a slightly different code for few EFs. However, there are no performance consequences on the use of these EFs.

Product Line:
Control Expert v14.1 and v15

Environment:
Types Library Manager

Resolution:
Update the project's types in order to be equal to library. A list of the concerned EFs is attached.

This issue is solved by applying "update with latest version available" during opening the project in the LIBRARY Version Management dialog. Besides, the project can be updated later as well, using the menu in the Types Library Manager.

NOTE: Take into account that once the project is updated, "Rebuild All" will be needed. After that, the PLC needs to be stopped to perform a global download.
