The problem comes from another problem: Can a DB be called by several FBs? The answer is no. by the way, my colleague told me that a DB can be read/ wrote by several FBs. So I would like to know that what is the difference between read/write and call. When I call a block, what happens? Thx. Hello, Please read more here to know what are the differences between an instance DB and a Global DB: What is the difference between an instance data block and a global data block and how does a CALL call influence the DB register?
and some points regarding your question:
