Programming Blocks Of The Cpu Program Part - Siemens SIMATIC S5 Manual

Control of the IP 265 by the CPU User Program
Advantage of parameter exchange via flag areas:
The CPU can access the parameters at any location in the CPU user program without having to
check each time whether the IP 265 is ready.
