In PLC programming, FB (Function Block) and FC (Function) are two commonly used programming elements. Their design purposes and data processing methods differ, which directly leads to FB requiring a DB (Data Block) while FC does not. Why does FB require DB? The static variables and input/output parameters of FB need to be persistently stored … Read more
