2.3 Ensuring Readiness for Service
Grounding Measures
Low-resistance grounding connections ensure that the user of the installation is
protected against electric shock (for example, if a short-circuit occurs or if there are
defects in the system). Moreover, they discharge interference transmitted by
external power supply cables, signal cables or cables to I/O devices.
You should therefore create a low-resistance connection (a large surface acting as
the contact) between the grounding point on the system housing and the central
grounding point of the cabinet or the installation in which the computer is to be
installed. The minimum cross-section should not be less than 5 mm2.
The grounding terminal is located on the side of the device and is identified by a
symbol.
Connecting to the power supply
Note
The computing unit is equipped with a safety-tested power supply cable and may
be connected only to a socket outlet with grounding contact.
Make sure that the socket outlet on the device or the socket outlet with grounding
contact of the building wiring system is freely accessible and located as near to the
device as possible.
The computing unit does not have a mains switch. To completely disconnect the
PC from the mains power supply, you must pull the plug. This connection must be
easily accessible.
If the PC is to be installed in a cabinet, a central disconnector must be provided.
The standard power supply of the computing unit is designed for 120/230 V
systems.
The power supply has automatic mains voltage changeover. There is no need to
adjust the voltage range.

3.7 Using the Computing Unit in a SIMATIC S5 Network
Point-to-point connection,
This section describes the options for connecting your computing unit to a
programming unit or an S5 programmable controller in a point-to-point connection.
A point-to-point connection is possible by connecting the computing unit to another
programming unit or a programmable controller by means of:
S a V.24 connection
S a TTY connection
Configuring notes for interfaces with current loop (TTY, 20 mA)

Different criteria have to be taken into account for reliable operation of a
connection. The maximum data transfer rate (baud rate) depends on the required
distance, the type of cable, the pin assignment of the interface and external
interference.
Rules
To reduce interference by a favorable choice and correct connection of the
cable, you should comply with the following rules:
S The shielded cable used must have a low line resistance
(< 130 W / km) and a low capacitance (< 90 pF/ m). Twisted-pair cables are
less susceptible to inductive interference. A low line resistance result in reduced
voltage excursions and shorter charge reversal times; the line resistance
decreases with increasing conductor cross-section for the same length of cable.
S The shorter the data transmission link, the higher the maximum possible
transfer rate.
S If there is an active transmitter and an active receiver at the same end of the
transmission link, the sequence of access priority to the transmission circuit
must be taken into account in order to achieve the longest possible
transmission link.
S Signal lines and power lines must not be run together. Signal lines must be
installed as far away as possible from sources of strong interference (for
example, 400 V 3-phase power cables).
S The active TTY interface with a 12 V open-circuit voltage has been tested on a
100 m long cable at a transmission rate of 9600 bps in an environment with
normal levels of noise (field strength < 3 V/ m). If a LiYCY 5 x 1x 0.14 shielded
cable is used, reliable transmission is possible over a distance of up to 100 m.
The AS511 driver was used for testing (only one transmitter at a time).
Note
The interference field of the source of interference is reduced by the square of
the distance.

PROFIBUS is an open and rugged bus system for industrial use. It can be used
to configure networks with up to 32 nodes per segment. PROFIBUS-DP
supports data rates of 9.6 KBaud to 12 MBaud.
How the network functions

The network operates on the ”token passing with subordinate master/slave”
principle (complying with DIN 19245, PROFIBUS). It distinguishes between active
and passive nodes. An active node receives the token and passes it on to the next
node within a specified time.
Hardware requirements
Using the following components, for example, you can connect or network the
computing unit to/with PROFIBUS:
S interface RS 485, MPI/DP interface, integrated
S shielded, twisted pair (bus cable or spur line)

4.3 Replacing the Backup Battery
Battery power supply for real-time clock and configuration

A backup battery (3.6 V lithium battery) powers the real-time clock even after the
device is turned off. In addition to the time of day, all the information about the
device (device configuration) is stored. If the backup battery fails or is removed
from its plug, these data are lost.
The clock uses very little power and the lithium battery has a high capacity so that
the battery can provide back-up power for the real-time clock for many years. The
battery seldom needs to be replaced for that reason.
Battery voltage too low

If the battery voltage is too low, the time is lost, and a correct configuration of the
device can no longer be guaranteed.
Replacing the battery

In this case, you must replace the backup battery. The battery is on the
motherboard.
To change the battery, perform the following steps:
1. Turn off you device, and remove the mains cable and all interconnecting cables.
2. Open the device as described in section 4.1.
3. Change the backup battery inserted in the motherboard by pulling out the cable and
undoing the cable tie.
4. Secure the new battery in its mounting with a cable tie.
5. Insert the battery connector in the motherboard.
6. Close the device.
Caution
! Danger of damage!
Only replace the lithium battery with an identical battery or with a type
recommended by the manufacturer (Order No: W79084-E1003-B1).
Dispose of used batteries in keeping with local regulations.
Improper replacement of the battery poses danger of explosion.

Edition 12/01 4-11
Backup battery removed
Figure 4-6 Position of the Backup Battery
Warning
! Danger of bodily injury and damage to property, danger of release of noxious
matter.
A lithium battery can explode if mistreated and noxious matter might be released if
old batteries are disposed of wrongly.
Do not throw new or empty lithium batteries into the fire, and do not solder on the
cell housing; do not recharge lithium batteries or force them open.
Obtain lithium batteries only from Siemens (Order No: W79084-E1003-B1).
If possible, return old lithium batteries to the manufacturer or recycling facility or
dispose of them as special garbage.
Changing SETUP
If you change a battery or unplug the battery connector, you must run SETUP to
reset your device’s configuration data (refer to Chapter 5).

4.11 Network Connections and Interconnections
4.11.1 Connecting the MPI/DP Port
Connecting a PROFIBUS-DP network via the MPI/DP port

You can connect the computing unit to PROFIBUS-DP networks via the isolated *)
MPI/DP port. The physical connection is established with SINEC-L2 components for
stationary connections or using the 5 m long MPI connecting cable for non-stationary
connections. SINEC-L2 components and MPI connecting cables are not included in
the scope of supply of the computing unit and have to be ordered separately. The MPI
connecting cable (5 m) can only be used for transfer rates up to 187.5 Kbaud.
To connect the computing unit to a PROFIBUS-DP network, perform the following
steps:
2. Plug the power lead (of SINEC-L2 components or MPI connecting cable) onto
the MPI/DP socket of your computing unit and secure the connector by
tightening the screw-type lock.
3. Turn your computing unit on.
Caution
Always discharge your body’s charge before inserting power leads and connecting
cables by briefly touching a grounded object (ESD Guidelines).
MPI/PROFIBUS-DP network
Up to 32 devices (computing units, programming devices, PLCs or DP
components) can be interconnected to form a network segment. The physical
connection to the PROFIBUS-DP network is via an isolated *) RS458 interface,
which is an integral part of the interface.
Several PROFIBUS-DP network segments can be connected via repeaters.
The complete PROFIBUS-DP network can consist of up to 127 nodes. The data
transfer rate on the MPI network is 187.5 kbaud, whereas on the PROFIBUS-DP
network data transfer rates of 9.6 kbaud to 1.5 Mbaud are supported by the
MPI/DP interface.
Note
You will find information on how to configure a PROFIBUS-DP network in the
manual ”Programmable Controller S7-300, Configuration, CPU Data” Order No.

4.11.2 Point-to-Point Connection
Point-to-point connection
This section describes the options for connecting your computing unit to a
programming unit or a programmable controller in a point-to-point connection.
A point-to-point connection is possible by connecting the computing unit to a
programming unit or a programmable controller by means of:
S a V.24 connection
S a TTY connection
You will find detailed notes in section 6.12.
Configuring notes for interfaces with current loop (TTY, 20 mA)

Different criteria have to be taken into account for reliable operation of a
connection. The maximum data transfer rate (baud rate) depends on the required
distance, the type of cable, the pin assignment of the interface and external
interference.
Rules
Observe the following generally applicable rules to reduce interference:
S The shielded cable used must have a low line resistance (< 130 W/km) and a
low capacitance (< 90 pF/m). Twisted-pair cables are less susceptible to
inductive interference. A low line resistance result in reduced voltage
excursions and shorter charge reversal times; the line resistance decreases
with increasing conductor cross-section for the same length of cable.
S The shorter the data transmission link, the higher the maximum possible
transfer rate.
S If there is an active transmitter and an active receiver at the same end of the
transmission link, the sequence of access priority to the transmission circuit
must be taken into account in order to achieve the longest possible
transmission link.
S Signal lines and power lines must not be run together. Signal lines must be
installed as far away as possible from sources of strong interference (for
example, 400 V 3-phase power cables).
S The active TTY interface with a 12 V open-circuit voltage has been tested on a
1000 m long cable at a transmission rate of 9600 bps in an environment with
normal levels of noise (field strength < 3 V/m). If a LiYCY 5 x 1x 0.14 shielded
cable is used, reliable transmission is possible over a distance of up to 1000 m.
The AS511 driver was used for testing (only one transmitter at a time).

4-32 Edition 12/01
Note
The interference field of the source of interference is reduced by the square of the
distance.
Connecting the computing unit to an S5 programmable controller

using the COM1/TTY interface.
1. Turn your computing unit off.
2. Plug the connecting cable onto the COM1 /V.24/PLC port.
Caution
! Danger of damage being caused to the device
If you interchange the connectors, or use wrong connecting cables, the port might
be damaged. Be careful not to plug the TTY cable in the LPT 1 port of the
computing unit instead of the COM1/TTY port.
Always discharge your body’s charge and the charge of connecting cables before
plugging in connecting cables by briefly touching a grounded object (ESD
Guidelines).
Use only the original connecting cable for the connection to the programmable
controller.
The computing unit and the programmable controller must be operated at the
same protective conductor voltage.
Connecting the computing unit via an adapter

An adapter is available for connecting the computing unit to the PLC with earlier
standard connecting cables.

cable. Cables of various lengths are available under the order number
6ES5 734-2xxx0 (xxx stands for the length code).
4.12 Reset Button
A hardware reset is initiated by means of the reset button on your device. The
computing unit is restarted (cold restart).
On the computing unit, the reset button is located on the drive side beside the
floppy disk drive. The reset button can only be operated with the aid of a pointed
object (for example, tip of a ball-point pen or elongated paper clip). The position of
the reset button is marked in the illustration of the computing unit below.

6.3 Hardware Address Table
In the distribution of the address areas a distinction is made between

S memory address space and
S I/O address space.
Different write/read signals (I / O WR, I / O RD, MEMR, MEMW) address these
different areas. The following tables will give you an overview of the address areas
used. Please refer to the descriptions of the individual function groups for more
details.
How memory decoding works

The Pentium II CPU has a memory address area of 64 Gbytes, of which 4 Gbytes
can be used. The CPU has 64 data lines, 33 address lines and 8 byte enable lines
(BE0 to BE7), which encode the non-available address lines A0, A1 and A2.
The CPU address bus is mapped via the PAC (system controller) to the PCI
address bus. The memory addresses of addresses 0000 0000h to 0009 FFFFh
(640 kbytes) and from address 0010 0000h to 2FFF FFFFh (768 Mbytes) are
excluded.
The ISA bridge PIIX (PCI ISA IDE Xcellerator) precisely maps the ISA address bus
once on the PCI address bus. The ISA address bus for 8 bit modules includes the
address area from A0 to A19, which corresponds to the CPU addresses 0000
0000h to 000F FFFFh (1 Mbyte).
For 16-bit ISA modules, the address bus is expanded by address lines A20 to A23
and therefore addresses from 0000 0000h to 00FF FFFFh (16 Mbytes). The
distinction between the 1 Mbyte and the 16 Mbyte ISA address areas is achieved
by special memory read/write signals which are activated only if address lines A20,
A21, A22 and A23 have logic zero level.
If address areas assigned to main memory or the PCI bus are addressed by the
CPU, no ISA bus control signals are generated. This means that an ISA bus
module is not addressed in these memory areas. Conversely, an ISA bus master
cannot reach addresses above 16 Mbytes. In order to obtain a larger address area
for dual-port RAM expansions than the memory address between 640 kbytes and
1 Mbyte, various decoding holes are provided on the Pentium PU basic board:
S The CPU address area FFF0 0000h to FFFD FFFFh (1024 k-128 k BIOS =
896 Kbytes) is mapped to the ISA address area 00F0 0000h to 00FD FFFFh
and is always addressed in the CPU address area. Decoding of the address
lines A24 to A31 missing on the ISA bus is accomplished by special hardware
on the basic board.
S The CPU address area 00F0 0000h to 00FF FFFFh is mapped in the ISA
address area 00F0 0000h to 00FF FFFFh (16 MB memory window). This
setting can be enabled and disabled by running Setup.

6.4 Interrupt Assignment
Interrupt assignment
Handling of the 16 hardware interrupts (IRQ 0 to IRQ 15) is taken care of by two
type 82C59 integrated interrupt controllers on the computing unit.
The INT output of the slave controller is connected to the IRQ 2 input of the master
controller. Interrupt 9 (IRQ 9) can be used on the bus for the assigned interrupt 2
(IRQ 2). IRQ 9 parameters are set to the software interrupt vector 0A H (IRQ 2) in
the initialization phase by the ROM BIOS.
Priority
The interrupts are prioritized in the reverse order of their numbering. Interrupt
IRQ 0 has the highest priority and interrupt IRQ 7 the lowest. For triggering IRQ 2,
interrupt IRQ 8 has the highest priority and IRQ 15 the lowest. Interrupts IRQ 8 to
IRQ 15 therefore have higher priorities than interrupts IRQ 3 to IRQ 7. The
interrupt vectors are initialized and masked when the computing unit is powered
up.

6-10 Edition 12/01
6.6 Monitoring Functions
The LEDs described in the following sections are only available on specific
versions of the device. The basic configuration of the computing unit does not have
any LEDs. The hardware signals are described in section 6.7.2.
6.6.1 Overview
Function
The following individual functions are implemented:
S temperature monitoring and indication of overheating and underheating
S watchdog
Messages can be passed by the monitor modules to applications.
The program SOM (Safecard on Motherboard) and drivers for Win NT and
Windows 98 are available on the devices for this purpose. These tools can be used
to display the status and assign parameters to limit values.
You will find a description of the drivers and the SOM program in the SafeCard
directory on the Documentation and Drivers CD supplied to you.
6.6.2 Signals at the Front-Side Port
The indications have the following meanings:
LED OFF YELLOW

Temp System turned off Inside temperature outside permissible range.

Edition 12/01 6-11
6.6.3 Temperature Monitoring and Display
Temperature monitoring
The temperature is acquired by three thermocouples. One thermocouple monitors
the processor temperature, the second monitors the temperature in the processor
module area and the expansion boards, while the third monitors the temperature in
the power supply module area. The following conditions result in a temperature
drift:
S temperature exceeds the threshold value for overheating
S temperature falls below the threshold value for underheating
The temperature thresholds can be set separately (by driver or SOM program).
One of the following reactions is triggered should the temperature drift:
Reaction Options
Temp LED from OFF to YELLOW Always
Trigger IRQ Adjustable
6.6.4 Watchdog (WD)
Function
The watchdog monitors the execution of a program. The purpose of the WD is to
report a program crashing to the user by means of different reactions.
The watchdog is idle when you turn on the computing unit or following a HW
RESET(cold restart) – in other words, no reaction by the WD is initiated.

6-12 Edition 12/01
WD reactions
If the WD is not retriggered within the set time (by driver or SOM program), the
following reactions are triggered:
Reaction Option
Acknowledge WD Always
Initiate reset on the computing unit Adjustable
Send IRQ on computing unit Adjustable
The reactions you want to have triggered can be set by drivers or the SOM
program.
WD monitoring times, TWD

The monitoring times can be adjusted in increments of one second over the range
from 3 to 255 seconds.
Note
If the watchdog time is modified after the watchdog has been activated – in other
words, while the watchdog is running – the watchdog will be retriggered as a
result!

Edition 12/01 6-13

Port to bus module (X1)

The computing unit has a bus module with a PCI expansion slot and a shared
ISA/PCI slot. Expansion boards can be installed complying with ISA specification
(Rev. 3.1) and PCI specification (Rev. 2.0) with a maximum length of 265 mm
(175 mm for shared ISA/PCI modules). All PCI slots can be used as masters. Only
5 V PCI modules can be operated.
The bus module is designed as a truly passive module – in other words, there are
only receptacles for the expansion boards and any backup capacitors that may be
present. The power supply of the expansion boards runs via the connection of the
bus module to the basic board. The -5 V voltage is not provided by the power
supply and is generated from the -12 V on the bus module using in-phase control.
The connection to the basic board is established by a gold-plated ’EISA’ type
two-part connector. All the necessary bus signals (ISA and PCI) are applied to this
connector. The following table shows the connector pin assignment.

ESD Guidelines C
What does ESD mean?
Virtually all present-day modules incorporate highly integrated MOS devices or
components. For technological reasons, these electronic components are very
sensitive to overvoltages and consequently therefore to electrostatic discharge:
These devices are referred to in German as Elektrostatisch Gefährdeten
Bauelemente/ Baugruppen: “EGB”
The more frequent international name is:
“ESD” (Electrostatic Sensitive Device)
The following symbol on plates on cabinets, mounting racks or packages draws
attention to the use of electrostatic sensitive devices and thus to the contact
sensitivity of the assemblies concerned:
ESDs may be destroyed by voltages and energies well below the perception
threshold of persons. Voltages of this kind occur as soon as a device or an
assembly is touched by a person who is not electrostatically discharged . Devices
exposed to such overvoltages cannot immediately be detected as defective in the
majority of cases since faulty behavior may occur only after a long period of
operation.
Precautions against electrostatic discharge

Most plastics are capable of carrying high charges and it is therefore imperative
that they be kept away from sensitive components.
When handling electrostatic sensitive devices, make sure that persons, workplaces
and packages are properly grounded.

Edition 12/01 C-1
ESD Guidelines
Handling ESD assemblies

A general rule is that assemblies should be touched only when this cannot be
avoided owing to the work that has to performed on them. Under no circumstances
should you handle printed-circuit boards by touching device pins or circuitry.
You should touch devices only if
S you are grounded by permanently wearing an ESD wrist strap or
S you are wearing ESD shoes or ESD shoe-grounding protection straps in
conjunction with an ESD floor.
Before you touch an electronic assembly, your body must be discharged. The
simplest way of doing this is to touch a conductive, grounded object immediately
beforehand – for example, bare metal parts of a cabinet, water pipe etc.
Assemblies should not be brought into contact with charge-susceptible and highly
insulating materials such as plastic films, insulating table tops and items of clothing
etc. containing synthetic fibers.
Assemblies should be deposited only on conductive surfaces (tables with an ESD
coating, conductive ESD cellular material, ESD bags, ESD shipping containers).
Do not place assemblies near visual display units, monitors or television sets
(minimum distance to screen > 10 cm).
Measuring and modifying ESD assemblies

Perform measurements on ESD assemblies only when
S the measuring instrument is grounded – for example, by means of a protective
conductor – or
S the measuring head has been briefly discharged before measurements are
made with a potential-free measuring instrument – for example, by touching a
bare metal control cabinet.
When soldering, use only grounded soldering irons.
Shipping ESD assemblies

Always store and ship assemblies and devices in conductive packing – for
example, metallized plastic boxes and tin cans.
If packing is not conductive, assemblies must be conductively wrapped before they
are packed. You can use, for example, conductive foam rubber, ESD bags,
domestic aluminum foil or paper (never use plastic bags or foils).
With assemblies containing fitted batteries, make sure that the conductive packing
does not come into contact with or short-circuit battery connectors. If necessary,
cover the connectors beforehand with insulating tape or insulating material.

restart. These files are CONFIG.SYS, AUTOEXEC.BAT and register files.
Configuration software
Configuration software updates the device configuration when modules are fitted.
This is done either by copying the configuration files supplied with the device of by
manual configuration.
D
Device configuration
The device configuration of a SIMATIC PC contains details about its features and
options such as memory capacity, drive types, monitor, network address, etc. The
data are stored in a configuration file and are used by the operating system to
select the correct drivers and device parameters.
When the basic configuration changes, the user can modify the settings using a
program that configures the system (SETUP).
Drivers
Program parts of the operating system. They convert the data of applications into
specific formats required by the peripheral devices (for example, hard disks,
monitors, printers).
