Siemens S7 TIA Portal
Both FCs and FBs are useful where a certain sequence of logic needs to be repeated and/or re-used in multiple places, but with different inputs and outputs.

Function block (FB)
A function block (FB) is a code block that uses an instance data block for its parameters and static data. FBs have variable memory that is located in a data block (DB), or "instance" DB.

Getting Started With Function (FC) Programming in TIA Portal
An FC (Function) is a reusable, stateless block of logic in TIA Portal. It has no internal memory (unlike FBs) and must receive its inputs and outputs during each call.

What should you watch out for in STEP 7 (TIA Portal) when
When the block is called, the value of the actual parameter is copied to the temporary data of the calling block. Writing a parameter in the called block does not lead to modification of the actual
