General remarks
The purpose of the function description of the blocks and of the interface is to illus-
trate the communication between the CPU and the FM 353 in the SIMATIC S7 pro-
grammable controller. The programmable blocks and the AW-DB (which is the in-
terface to the FM 353) make it possible for you to write your user program to suit
your particular application.
