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.

2.10 Connecting the Operator Panels and Peripherals

The operator panels and peripherals which can be connected to your FM 456-2
depend on its configuration.

M7-SYS user

Extensive information on all connection options of the FM 456-2 can be found in
the appropriate sections of the technical data.

To prepare for operation, you need either a PC/PG or the M7-400 configuration
with monitor, keyboard, expansion module, and mass storage module as well as
interface submodules.

For reasons of noise immunity of the entire system, we recommend that you use
the standard connecting cables available from Siemens for connecting the
peripherals.

Connecting a VGA Monitor

To be able to connect a VGA monitor to the FM 456-2, an IF 962-VGA interface
submodule must be fitted in the card slot of the FM 456-2 or of a corresponding
expansion module. Connect the monitor to the 15-pin high density subminiature D
socket of the IF 962-VGA interface submodule (up to 2.5 m).

Connecting a Keyboard

Notes for Setting Up Monitors

Please observe the following notes when setting up monitors.
 Ensure that the clearance between two monitors in asynchronous operation is

at least 15 cm, otherwise video interference may occur.
Exception: monitors with a mu-metal shield.

 Provide sufficient space between the monitor and extraneous magnetic

sources.

 Do not set up the monitors in steel shelving or on steel benches. Magnetization

of the surrounding sheet steel can result in false colors or video shifting.

 Avoid setting up monitors in the vicinity of transformers, radio transmitters,

magnets and power cables.

 The effects of extraneous magnetic fields can be attenuated by using a

mu-metal shield.

Special Conditions when Using Office Monitors

Additionally, you should observe the following notes when setting up office
monitors:

 Office monitors with an internally metallized plastic housing should not be used

in an environment subject to electromagnetic interference, because the internal
metal surface cannot be subsequently connected to the external ground bus.
The required isolation of the electronics ground from the housing ground of the
monitor - essential for an environment subject to electromagnetic interference ­is not possible with most office monitors.

 You can only use such monitors in conjunction with conventional VGA cables.

Connection to the M7-400 is therefore only possible with limitations, because
you can only cover short distances with these cables.

Connecting Printers

You can connect printers with a serial or parallel interface.
 A printer with a parallel interface should be connected with the appropriate

connecting cable (see ordering information) to the IF 962-LPT interface
submodule.

 A printer with a serial interface should be connected with the appropriate cable

(see ordering information) to the COM interface submodule.

We recommend the use of Siemens printers.

2-22

Note

Only a connection cable with screen grounded at both ends may be used to
connect between an M7-400 component and a printer.

3.1 Replacing the Interface Submodule

Removing the Interface Submodule

You can replace the interface submodule with another without removing the
associated application function module or expansion module. To do this, proceed
as described below:

1. Switch the central module and all function modules in your S7/M7-400 system
to STOP with the key switch.

2. Switch off the load supply voltage to the modules.

3. Set the standby switch on the power supply module to the position (output
voltage 0 volts).

4. Loosen the screws retaining the Sub-D connectors and pull out all plugs.

5. Loosen the two captive slotted screws fixing the front plate of the interface
submodule to the left hand frame of the module card slot sufficiently to pull
these out about 6 mm (1/4 inch).

6. Pull the interface submodule carefully out of the guide of the card slot (see
Figure 3-1).

Caution

!

There is the risk of injury to persons and damage to property.
As the surface temperature of the modules can reach up to 70 °C, there is the risk

of burning. Therefore always grasp the front plate of the interface module at the
long sides.

Interface modules contain electrostatically sensitive devices which can be
damaged when being touched.

Observe the ESD rules when fitting the interface modules.

4.5 Memory Card

The FM 456-2 application function module provides a facility to use memory cards
as data medium or mass storage. This section provides you with information on
how to use this facility.

Note

If a power failure occurs during write access to the memory card, the entire
content of the memory card may be corrupted under worst case conditions.

Please note that, unlike a diskette, the memory card with flash EPROM is only
suitable for a limited number of write operations.

A memory card simulates a diskette drive from which the operating system can be
booted. It can also be used for changing user software and data.

For the FM 456-2, memory cards with flash EPROM are available (see Section 5,
“Ordering Information”).

reference

UNDELETE:
Files which were deleted from the memory card cannot be restored using
UNDELETE programs.

4.6 Expansion Socket

The FM 456-2 application function module is provided with an expansion socket,
allowing you to connect up to three M7-400 expansion modules. The ISA bus is
extended via the expansion socket.

Which Expansion Modules Can Be Connected?

One EXM 478 extension module with up to three interface submodules, one
MSM 478 mass storage module with diskette and hard disk drive or one ATM 478
AT adapter module for short AT cards can be connected directly to the FM 456-2
application function module.

A total of up to 3 expansions can be connected in series to the CPU.
If three EXM 478 expansion modules are connected, up to 11 interface modules

can be operated together with the slots on the relevant application function
module.

Assembly Rules

The rules for the sequence of assembly and the possible combinations of
expansion modules can be found in the chapter “M7-400 Expansion Modules” in

manual /1/

4.7 Slots for Interface Submodules

Definition

The submodule slot is a receptacle for a submodule. The FM 456-2 application
function module has a slot for the memory card and two slots for interface
submodules.

Figure 4-4 shows the position of the two slots for interface submodules on the
FM 456-2 application function module.

Slot Numbering

Each slot for an interface submodule has a submodule slot number assigned to it.
The submodule slot number depends on the module slot and on the arrangement
of the slot on the expansion module or the CPU. You can see the submodule slot
numbers in Figure 4-5.

FM 456-2 Functions and Technical Data

You require these submodule slot numbers for configurations that you undertake in
the BIOS setup or for determining the I/O addresses of an interface module (see
the chapter “Expansions for M7-400” in the

Module slot

4.8 Watchdog

Method of Operation

The FM 456-2 contains a watchdog for monitoring user programs. This is called on
a cyclic basis by the system software. If the cyclic operation fails (for instance, if
the software “hangs”), the module is reset after the watchdog period has expired.
The cause of the reset is stored and is evaluated by the diagnosis software.

4.9 Buffering

The S7-400 rack is buffered centrally by the back-up battery in the power supply
module.

If central buffering is present, the time and date and the SRAM (256 Kbytes) is
buffered on the FM 456-2 application function module.

FM 456-2 Functions and Technical Data

BIOS Setup

Note

Note that the data content will be lost if the central buffering fails or the module is
unplugged from the rack.

The BIOS setup data, excluding time and date, is stored in the BIOS flash EPROM
and is therefore independent of the central buffering. The BIOS setup is retained if
the central buffering fails or the FM 456-2 is removed from the rack.

4.11 Address and Interrupt Assignments

This section contains detailed information in tabular form about I/O address area
mapping, memory and interrupt assignments in the FM 456-2 application function
module.

Memory Assignment

The main memory is assigned as follows in the FM 456-2:

Table 4-5 Main Memory Assignment

Address Content

1 MB to 15 MB
E 8000H to F FFFFH BIOS
E 0000H to E 7FFFH Free (32 K)
D 4000H to D FFFFH Free (48 K)

*)

or to 16 MB User memory area

D 0000H to D 3FFFH Reserved for CP 1401 (16 K)
C F000H to C FFFFH Free (16 K)
C C000H to C EFFFH Memory card, otherwise free (12 K)
C 8000H to C BFFFH Reserved (32 K)
C 0000H to C 7FFFH Shadow VGA BIOS (32 K)
A 0000H to B FFFFH VGA (128 K)
0 0000H to 9 FFFFH 640 K system area

*)

If the interface submodule IF 964-DP is not plugged in the preferred slot (see
page 4-10)

Keeping Memory Areas Free

The memory areas that are not always marked as “free” should be kept free when
using a memory manager.

SRAM Area

The size of the SRAM with battery backup is 256 Kbytes (net for data blocks
244 Kbytes). If the battery is removed and inserted again when there is no power
connected, the SRAM content will be lost. This is indicated by the BAF LED.

Memory Areas for AT Cards

AT cards which are inserted in the expansion module ATM 478 can occupy the
following memory areas:

D 0000H to E 7FFFH 96 K 96 K 32 K
C 8000H to C BFFFH 16 K 16 K 16 K
C C000H to C EFFFH
C F000H to C FFFFH 4 K 4 K 4 K

1)

The area is only available if no memory card is present.

2)

If the driver software under MS-DOS requires expanded memory (EMS), the
memory manager EMM386 occupies 64 K in the area D0000H to E7FFFH
because it must be operated in EMS mode.

I/O Address Area

Addressing of the ISA-compatible input/output components is carried out in the I/O
area at addresses from 0100H to 03FFH. The addresses determined by the ISA
architecture are used. Unlike the original AT, the I/O addresses are fully decoded in
the FM 456-2 module, so that addresses above 03FFH can be used for addressing
M7-400-specific hardware.

Rules for Handling Electrostatically
Sensitive Devices (ESD)

Introduction

This appendix explains

 What lies behind the term “electrostatically sensitive devices”
 What precautions must be observed when handling electrostatically sensitive

modules.

Contents

You will find the following information about electrostatically sensitive modules in
this appendix:

Rules for Handling Electrostatically Sensitive Devices (ESD)

B.1 What Does ESD Mean?

Definition

All electronic modules are equipped with highly integrated devices or components.
Because of their technology, these components are very sensitive to overvoltages
and therefore to static electrical discharges.

The abbreviation ESD is used internationally for these Electrostatically Sensitive
Devices. In Germany these are referred to as EGB (Elektrostatisch Gefährdeten
Baugruppen).

Electrostatically sensitive devices are identified with the symbol shown below:

Caution

!

Electrostatically sensitive devices can be destroyed by voltages well below those
that you can normally detect. These voltages occur when you touch a component
or the connections of a module without having first ensured that you are
electrostatically discharged. The damage that can be caused to a module by
overvoltage cannot usually be recognized immediately, but only becomes apparent
after a lengthy period of operation.

B.2 Electrostatic Charging of Persons

Charging

Any person whose electrical potential is not equalized to that in their environment
can become electrostatically charged.

Figure B-1 shows the maximum electrostatic voltage with which a person can
become charged when coming into contact with the materials shown. These values
correspond to the figures in IEC 801-2.

Rules for Handling Electrostatically Sensitive Devices (ESD)

B.3 Basic Precautions Against Electrostatic Discharge

Ensure a Good Ground

When handling electrostatically sensitive modules, ensure that persons, workplace
and packaging are effectively earthed. This will avoid static charging.

Avoid Touching Components Directly

Only touch electrostatically sensitive components if this is unavoidable (for
example during maintenance work). Hold the module so that you do not touch
either the module pins or the printed circuit tracks. In this way, the electrical
discharge energy will not be able to reach sensitive components and cause
damage.

If you have to take measurements on a module, first discharge any static about
your body before carrying out the work. This can be done by touching a grounded
metallic object. Use only grounded measuring instruments.
