Product Overview

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.

Configuration of an S7-400 with FM 456-2

An FM 456-2 with or without expansion modules can be installed in addition to the
S7-400 components. Figures 1-1 and 1-2 illustrate sample configurations:

Installation and Startup

This section provides you with some brief information about the necessary steps to
start up an FM 456-2.

The startup activities can be divided into several steps, which should be carried out
in the order shown:

1. Installing and switching on the hardware

2. Load operating system, adapt BIOS setup if necessary

3. Load user software into the FM 456-2 from PG/PC, test and commission. Adapt
S7/M7 software to the FM 456-2 functions.

The activities you must carry out in step 1 of the startup process are shown below
in the correct order in form of a checklist. The checklist contains notes on where
you can find detailed information on each point.

2.3 Installing Interface Submodules

The EXM 478 expansion module has three card slots to accept interface
submodules. The FM 456-2 application function module has two card slots.

Warning

!

The modules can become damaged.
If the interface module is inserted or removed with the power on, the FM 456-2,

the expansion module or the interface submodule may be damaged.
Never insert or remove the interface submodule with the power on. Always switch

off the power supply (PS) before inserting or removing interface submodules.
Observe the ESD rules when installing an interface submodule.

Installing Interface Submodules

Proceed as follows to install an interface submodule in a card slot:

1. Hold the interface submodule on the long sides of the front plate.

2. Insert the PCB end of the interface submodule in the upper and lower guides of
the card slot as shown in Figure 2-1.

3. Slowly push the interface submodule into the slot until the connector on the
interface submodule latches into the slot and the front plate lies flush against
the edge of the slot.

4. Secure the front plate with the two fitted, captive M2.5 x 10 slot-headed screws
on the left frame of the card slot.

Warning

!

The interface submodules and the connected equipment can become damaged.
The interface submodules and the equipment connected to them may be

destroyed if the submodules are connected to the wrong front plugs.
Label the front plugs so that the associated interface submodule can be clearly

identified.

Covers for the Unused Card Slots

When the application function modules and expansion modules are delivered, only
the upper card slot is open. All other card slots are covered. The cover is secured
to the frame of the card slot with screws.

Slacken the screws and remove the cover to insert more than one interface
submodule in an expansion module.

2.4 Installing a Short AT Card

The ATM 478 AT adapter module can accept a short AT card. An AT module can
only be installed if the ATM 478 AT adapter module is not mounted. Only short AT
cards with a slot in the mounting bracket can be installed (see also the chapter on
M7-400 expansion in the

Warning

).

Installing the AT Card

Proceed as follows to install an AT module in an ATM 478 AT adapter module:

1. If the ATM 478 AT adapter module is installed in the rack, you must remove the
module assembly and extract the ATM 478 AT adapter module from this
assembly.

2. Remove the cover from the upper left side of the ATM 478 (see Figure 2-2).

3. Remove the mounting bracket for the AT module from the upper front of the
ATM 478 by undoing the screw (see Figure 2-2).

4. Insert the AT card into the slot from the front (see Figure 2-2).

5. Press the AT card through the side opening and at the front downward into its
connector until it engages. Ensure that the AT module support plate slides
under the metal spring on the front of the ATM 478 (see Figure 2-2).

6. Fit the mounting bracket over the angled part of the support plate of the AT card
and screw it onto the support plate of the AT card and to the ATM 478 (see
Figure 2-2).

7. Fit the cover to the upper left side of the ATM 478.

2.5 Fitting Expansion Modules to an FM 456-2

Before installing your M7-400 in the module rack, you must pre-assemble the
FM 456-2 application function module with all necessary expansion modules.

This section provides information that you will need to pre-assemble expansion
modules, such as an EXM 478 expansion module, an ATM 478 AT adapter module
and an MSM 478 mass storage module, to an application function module to form
a module assembly.

Assembly Sequence

Carry out assembly in the following sequence:

1. Remove the covers over the plugs and sockets on the modules.

2. Remove the connecting clips that are fitted at the top and bottom of the module.

3. Remove the module covers.

4. Position the modules on a level surface and interconnect them.

5. Clip the modules together with connecting clips at the top and bottom.

The individual steps for fitting expansion modules are illustrated on the following
pages.
