Please note Function and Function Block both are subroutine
in case of s7-300 & 400. Whenever you are writing
structured program you make use of them.
The basic difference between them is Fuction(FC) don't
require addition memory block they can exist on their own.
Whereas Function Block(FB) compulsorialy require a memory
dedicated to it called as Data Block(DB). This data block
is called as Instance Data block as only that particulcar
FB can use it.
Function Block is used when after each call operation in
initial /input value needs to be changed.
