Dears,

I'm facing an annoing issue with CFC F charts. After install the necessary software packages, when i try to modify the F logics, this error appear

This happen with the F charts or library only.

These are the installed packages.

These are the errors during the compilation

The necessary licenses are all installed.

Does anyone knows why this happen?

Any suggest to try?

Thanks.

Duccio

Solved,

For some reasone F System 6.4 upd1 doesn't complete the installation.

so, for step7 F-System was not installed.

Problem has been solved with the installation of F System 6.4 SP1.

OS was Win 10 Enterprise LTSC 21H2.

Duccio.
