Every time i excecute a read or write operation i havethis message: " SFCnot loaded SFC number: 84 Module Address: 608 Requested OB programming error OB(OB121) " This happens even after a full compile-download. My question is: Do i have the wrong S7 version? my controller is a CPU 416-2 Please, any help will be greatelly apreciated. we make lot of changes to the production line (Recipe configuration changes) and in order to have up to day backup is by going online with the processor and manually copy those DBs.If ican get the READ_DBL and WRIT_DBL to work, the next step will be automate the backup operation from wincc (HMI) Ps: I am having some problem openning your sample project. Thanks
