1.1 Overview
Introduction
In this section, you will learn what the FM 456-2 application function module is and
what it has to offer.
What Is an FM 456-2?
The FM 456-2 is an application function module from the M7-400 family of
automation computers that is used in the S7/M7-400 programmable logic
controller.
The FM 456-2 application function module is an automation computer with PC-HW
architecture for inserting in your S7/M7-400 programmable logic controller rack.
The FM 456-2 is a freely programmable module (application function module) that
can be expanded or combined to form large configurations:
Programmable module with Pentium, 120 MHz; a memory card and up to two
interface modules can be plugged in at the front.
EXM 478 expansion module, each for fitting 3 interface submodules such as
IF 962-VGA, IF 962-COM, IF 962-LPT.
MSM 478 mass storage module with diskette drive, hard disk and “LPT1”
parallel interface.
ATM 478 AT adapter module for installing a short AT module.
Position of an FM 456-2 in the S7 System
Within an S7/M7-400 system an FM 456-2 can be expanded with monitor,
keyboard and mass memory. Integration into the system is performed by the M7
system software.
You can use an FM 456-2 to provide flexibility in meeting specific requirements,
such as application technology tasks (controlling, positioning, metering, ...),
communications, data storage, etc. This considerably reduces the load on the
S7/M7-400 CPU.
