Hello!

We are working on a project that has some CFC logics (the CFC version is v8.0).

When we try to download the CFC we are facing the following errors:
E: The interface of block ... [FB..] has been changed. Please reimport.

(As reference, the complete log is in the attached screenshot).

The interessed FB have not been modified.
This is what we have already tried:

1. Updated the block calls (only in the OB where the FB are called) and "check and update accesses"
2. Performed a block consistency check
3. Generated the STL source file for all the FB involved (including the referenced blocks was not possible due the using of protected blocks), and recompilation.
4. Tried to compile the STL source for the CFC and recompile from this one.

Do you have any hints for this issue?

Thanks in advance.

Hi onofriol,

When a block interface has been changed, you cannot undo this. You need to retrieve a backup.

 Thank you for the answer Hazard_7.

When a block interface has been changed, you cannot undo this. You need to retrieve a backup.

Actually I do not want to undo the interface change of these FB.
Is there any way to update the CFC and download them?

The other thing that I don't understad is how these FB are linked with CFC logics, apparently there is no direct reference between them.

Thank you very much for this trick, it has solved the problem!

Thanks also for the clear video.
