PROFIBUS is for data communication between programmable controllersmade by different manufacturers.
The multi-point interface (MPI) is an integrated interface onprogrammable controllers such as SIMATIC® or SIMOTION as well as on
SIMATIC PCs, PGs and Panels.
Industrial Ethernet (IEEE 802.3 and 802.3u) is the international standardfor area networks, and is currently the number one network in the LANlandscape worldwide.
In point-to-point communication, two stations interchange data withone another. The point-to-point structure represents the simplest formof communication.
Process or field
communication is
supported by the
AS-Interface and
PROFIBUS DP
networks.
PROFIBUS (IEC 61158/EN 50170) is the international field standard, andis the world market leader among field buses.
As low-cost alternative to a wiring harness, AS-Interface connectssensors and actuators using a two-wire cable.

EIB (for integrating building services
automation). Centralized and
distributed I/O are configured in the
exact same way.
SIMATIC IT
Siemens recently expanded the Totally
Integrated Automation solution platform
to include Manufacturing Execution
Systems (MES). SIMATIC IT forms the
bridge between automation level and
corporate management level.
Component based Automation
based on PROFInetComponent based Automation is the TIA
concept for modular plant and machine
construction. It utilizes the benefits of
component technology, which has
already successfully established itself in
the software world. PROFInet, the
communication standard developed by
PROFIBUS International, is used for
communication.
Protocol applications (e.g.
PROFIBUS DP).
Allocation of products (e.g.
CP) to automation systems
(e.g. controllers) in the

technical specifications for
the various bus systems.
Totally Integrated Automation
Totally Integrated Automation® (TIA)
stands for a complete line of automation
components providing the very highest
level of integration: three-fold integration.
� An integrated software toolset supports
all project phases, from hardware
selection over programming and
operation to diagnostics and
maintenance.
� All tools access a common database,
saving configuring overhead and
ensuring project-wide data consistency.
� Communication within TIA is integrated
from the field level to the process
control level: Industrial Ethernet,
PROFIBUS with AS-Interface as
extended arm (for interfacing switching
and installation technology),
Integrated communication plays adecisive role
As economically-priced alternative to the
cable harness, AS-Interface connects
sensors and actuators over a two-wire
cable.
The basis for building services automation
is the international EIB standard
(EN 50090, ANSI EIA 776).
The multi-point interface (MPI) is an
interface integrated in SIMATIC® S7®/C7®
programmable controllers, SIMOTION,
and SIMATIC PCs, PGs and OPs/PPs/TDs.
The MPI makes it possible to set up short-
distance communication networks.
PROFIBUS (IEC 61158/EN 50170) is the
international standard for the field level,
is the world market leader among field
buses, and provides powerful process or
field communication.
Industrial Ethernet
(IEEE 802.3 and 802.3u) is the
international standard for area networks.
At present, Industrial Ethernet is the
number one network in the LANlandscape, with a market share of over
80%. Industrial Ethernet is used to set up
powerful long-distance communication
networks.
Industrial Mobile Communication
Industrial Mobile Communication is the
term used for industrial mobile
communication products (such as MOBIC)
from SIMATIC NET which use wireless
communication. The basis for Industrial
Mobile Communication are worldwide
networks such as WLAN (to IEEE
802.11b), GSM, or the networks of the
future, UMTS. Thanks to the growing
versatility of information technology,
Industrial Mobile Communication is being
used with increasing frequency in the
world of automation.
Industrial communication
Network interfaces are implemented
via programmable controllers or links.

Process or field communication
AS-Interface
Valves, actuators, drives � many differentcomponents are used at the field level.
All of these actuators/sensors must be
interfaced to an automation system.
Today, distributed I/O are being used at
the field level as intelligent on-site
outposts, so to speak.
Process or field communication is
supported by the AS-Interface and
PROFIBUS DP networks
AS-Interface
At the field level, one finds numeroussensors and actuators. As price-efficient
alternative to the cable harness,
AS-Interface connects these components
using a two-wire cable.
AS-Interface is used where individual
actuators/sensors are spatially distributed
throughout the machine (e.g. in a
bottling plant).
AS-Interface is the open international
EN 50295 Standard. All over the world,
leading manufacturers of actuators and
sensors support AS-Interface. Interestedcompanies have full access to the
electrical and mechanical specifications
for this interface.
Safety at work
The 'safety at work' concept enables the
integration of fail-safe components such
as Emergency Stop switches, safety door
switches or fail-safe light grid in anAS-Interface network. These components
are fully compatible with familiar AS-I
components (such as master, slaves,
power supply, repeaters, etc.), are based
on EN 50295 and are jointly operated on
the yellow AS-i cable.

AS-interface is a single-master system.Communications processors (CPs) are
available for SIMATIC families which serve
as master for controlling processor or
field communication.
Extended AS-Interface Specification V2.1
permits interfacing of up to 62 slaves.
Thanks to the integration of analog-value
processing in the masters, accessing
analog values is just as easy as accessing
digital values. A DP/AS-Interface Link is
used to interface the SIMATIC S7-400®
to the AS-i network. DP/AS-Interface Link
20E in IP20 is available for connecting
the AS-Interface network directly to
PROFIBUS DP, making it possible to use
AS-i as PROFIBUS DP subnetwork.
This is how you save costs
AS-Interface replaces high-overhead
cable harnesses and connects binary
actuators and sensors such as proximity
switches, valves and indicator lights to a
programmable controller, for example
SIMATIC. In practice, this means problem-
free installation, since data and power
are transported over a single cable.
Thanks to a specially developed cable
and cable-piercing technology, the
AS-Interface cable can be tapped at any
point. This concept gives you enormous
flexibility and is exceptionally cost-saving.
Special knowledge of installation and
commissioning are unnecessary. In
addition, easy cable installation, a clear
cable structure and the special design of
the AS-i cable not only greatly reduce the
risk of errors, but also the overhead for
service and maintenance.

PROFIBUS links field devices such asdistributed I/O or drives with automation
systems such as SIMATIC S7
programmable controllers, SIMOTION or
PCs.
PROFIBUS, which is based on the
IEC 61158/EN 50170 Standard, is a
powerful, open, rugged fieldbus system
with short response times.
The following protocols are available for
process or field communication with
PROFIBUS:
PROFIBUS DP
(distributed peripherals)
PROFIBUS DP is used to connect
distributed field devices such as SIMATIC
ET 200® or drives with very fast response
times.
PROFIBUS PA
(Process Automation)
PROFIBUS PA is an expanded version of
PROFIBUS DP which offers intrinsically
safe data and power transmission (e.g.
measuring transducers in the foodindustry) in conformance with
International Standard IEC 6158-2.
PROFIBUS DP/PA is used when
actuators/sensors in the machine or plant
(e.g. at the field level) are widely
distributed and can be spatially combined
in a single station (such as the ET 200).
In this case, the actuators/sensors are
connected to the field devices, which are
supplied with output data as per the
master/slave principle and provide the
controller or PC with input data.At SIMOTION's drive interface, the
isochrone PROFIBUS is supported by
PROFIdrive's "drive engineering" profile.

Powerful tools such as STEP 7®, COMPROFIBUS and SIMATIC PDM are available
for configuring and assigning parameters
to the I/O devices. In STEP 7, centralized
I/O and distributed I/O are configured in
exactly the same way.
PDM (Process Device Manager) is the
parameter assignment tool for intelligent
field devices (parameter assignments,
diagnostics), and is called from STEP 7.
STEP 7 can be used to make changes in
user programs as well as to test and
commission SIMATIC programmablecontrollers interfaced via PROFIBUS DP
from any point in the plant. Drive ES also
makes it possible to engineer the drives
from any point in the plant.
The S7-PDIAG/S7-GRAPH and ProAgent
diagnostic tools make it possible to carry
out process diagnostics without the need
for additional diagnostic instruments.

Lateral data communication on thePROFIBUS DP
Lateral communication on the PROFIBUS
DP makes communication even faster and
easier. The master sends a message
containing setpoint values to the first
slave. The slave responds by sending its
actual values in a broadcast message,
which is heard by all the other nodes on
the bus. Recipients are mainly intelligent
devices with their own data preprocessing
capability (distributed intelligence), such
as drives or distributed PLCs. Lateralcommunication requires no additional
message.
Master/slave and lateral communication
relationships can be combined as needed.
Isochrone mode (equidistance) canbe set to a µs! Ideal for closed-loop
control!
A precisely reproducible bus cycle time
is a requirement for sophisticated closed-
loop control, positioning and motion
control applications. Every deviation can
result in instable processes. Reprodu-
cibility with jitter of < 1 µs satisfies the
very strictest requirements, e.g. for
applications involving synchronism.
Drives, CPUs and modular slaves are
synchronized to a common clock pulse,not only making it possible to perform
motion control tasks, but also enabling
precise execution of distributed general-
purpose closed-loop control and
measuring tasks.
Process or field communication
PROFIBUS DP/PA
Acyclic data interchange
In addition to the cyclic exchange of user
data, PROFIBUS DP also enables acyclic
messages. This makes it possible to send
event-controlled data to the slave, e.g.
drives can be easily assigned new
parameters dynamically while the plant
or machine is in operation.

Openness all along the line
Thanks to PROFIBUS DP's openness, it
goes without saying that it is possible to
interface standardized components from
different manufacturers.
The IEC 61158/EN 50170 ensures
investment security for the future.
More than 2,000 products and services
from around 300 member companies all
over the world offer a wide range of field-
level products with PROFIBUS DP
interface.
Siemens itself offers a complete paletteof programmable controllers, network
components, communication software
and field devices.
And if you are a manufacturer of field
devices, we can supply you with virtually
everything related in any way to the
PROFIBUS interface, such as ASICs,
training, certification, and much more.

Process or field communication
Typical practice-related data
A list of the field devices which can be interfaced tothe relevant networks for the purpose of process orfield communication.
Configuring and commissioning can be done anywhereon the network.
The freely selectable communication relationships arethus extremely flexible, easy to convert, and easy tochange.
Slaves are network nodes on the PROFIBUS whichsend data back to the master at the master's request.
AS-i is a single-master system with cyclic polling.The AS-i cycle time is the time it takes for the master
to poll the slaves, which is done at preciselypredetermined intervals.
The term 'interface' or 'interfacing' is understood tomean the physical method of connecting bus nodesto the bus cable.
The bus cycle time is understood to mean the time ittakes for each master (active bus nodes) to receive
the token (the right to send) precisely once.
When using electrical components, local networkscan extend over the distance defined in the standards.
Greater distances can be bridged using opticalcomponents.
The method of cabling used between the stations isreferred to as the network topology.
Transmission media are either two-wire cables or fiber- optic cables.
The degree of protection is shown as IPxy, wherebythe first digit (x) refers to shock-hazard protection aswell as protection against solid bodies.
The second digit (y) indicates protection against water.The higher the digit, the greater the protection.
Standards are international norms or guidelines stipulating product properties and characteristics.
In some networks, the power supply for the bus nodes is also supplied by means of the bus.

PG/OP communication
These are integrated communication
functions which allow SIMATIC and
SIMOTION systems to communicate with
every HMI device (TD/OP) and SIMATIC
PG (STEP 7). PG/OP communication is
supported by all networks (with the
exception of MPI), e.g. commissioning
(coexistent interface).
S7 communication
For S7-400, S7 communication is the
integrated communication function SFB
(System Function Block), and for S7-300
it is loadable FBs optimized in the
SIMOTION and SIMATIC S7/C7 systems.
It also makes it possible to interface PCs
and workstations.
The amount of useful data per request
may not exceed 64 kbytes.
S7 communication provides simple,
powerful communication services as well
as a network-independent software
interface.
S5-compatible communication
(SEND/RECEIVE)
S5-compatible communication
(SEND/RECEIVE) enables SIMATIC S7/C7
to communicate with existing systems,
above all with SIMATIC S5®, as well as
with PCs via PROFIBUS and Industrial
Ethernet.

The decision as to whether multi-pointinterface (MPI), PROFIBUS or Industrial
Ethernet should be used for data
communication depends mainly on the
size of the area that must be covered by
the network, the amount of data
involved, the number of nodes involved
and the network's expandability.
A basic contingent of communication
functions on the networks ensures
consistency, that is to say, the functions
show virtually the same performance
capability over all of these networks.

consists of standardized protocols for
data communication, such as FTP.
PROFInet
PROFInet communication services are
used for data interchange between
PROFInet components via Ethernet, andare configured graphically using a
vendor-independent engineering tool
called SIMATIC iMap.
OPC
(OLE for Process Control)
OPC is a standardized, open, vendor-
independent interface, and is used to
interface OPC-capable Windows applica-
tions to S7 communication and S5-com-
patible communication (SEND/RECEIVE).
Information Technology (IT) with
e-mail and Web technology
This form of standard communication
links SIMATIC to IT via Industrial Ethernet.
In office environments, e-mail and Web
browsers have become widely-used
communications resources.The most
widely accepted communication path is
Ethernet, although telephone lines and
the Internet are also popular.
Socket interface for Industrial
Ethernet
This interface enables data communica-
tion with computers via TCP/IP. Users can
program their own protocols for thisinterface, which is widely used in the PC
world as well as in the UNIX world. In
the SIMATIC S7, the SEND/RECEIVE (S/R)
blocks are used as portal to TCP/IP.

Industrial Ethernet is a powerful area andcell network based on the IEEE 802.3
(ETHERNET) Standard.
Ethernet is also the technology on which
the Internet is based, and offers many
possibilities for worldwide networking.
The many possibilities provided by
intranet, extranet and Internet already
available in today's office environments
can also be utilized in production and
process automation.
Ethernet technology, which has been
successful over many years, in combi-nation with switching, full-duplex mode
and autosensing allows you to match your
network's performance to your
requirements.
You can choose your data throughput
rate to suit your particular needs, since
integrated compatibility makes it possible
to introduce the new technology in
stages.
With a market share of over 80%, Ethernet
is number one in today's LAN landscape
worldwide. Ethernet provides importantproperties and performance characteris-
tics which can mean many important
benefits for your application:
� Fast commissioning thanks to simple
yet sophisticated connection systems.
� High availability, since existing plants
can be expanded without perturbation.
� Virtually unlimited communication
capabilities due to scalable performance
through switching technology.
� Networking of widely varied types of
applications, such as office andproduction applications.
� Company-wide communication thanks
to WAN (Wide Area Network) link-ups
such as ISDN or Internet.
� Investment security thanks to retention
of compatibility in future development.

TS 980 / TS-MOBIC teleservice
Is used for telecontrol of a PC or PG
integrated in the plant by way of IndustrialEthernet.
In addition to the TS client, all software
tools that are to be used must be installed
on the PC or PG in question (e.g.
diagnostic software such as STEP 7 or
ProTool/Pro).
Only the TS 980 software executes on
the remote PC/PG.
Telecontrol
The SINAUT telecontrol system makes it
possible to set up complex, widely
distributed networks using narrow-bandtransmission media. This makes it possible
to use not only private lines or wireless
connections in communication projects,
but also leased lines or public networks
such as ISDN, GSM or the analog telephone
network, and to combine them as needed.
Data communication
Worldwide communication
Teleservice
Progressive plant automation and
increasingly extensive globalization ofcompanies are requiring more and more
frequent access to teleservice systems
via stationary or radio networks.
SIMATIC teleservice
The MPI interface on SIMATIC S7/C7,
SIMOTION automation systems and OPs
is extended by means of the public
telephone network. This requires nothing
more than a TS adapter and a modem.
The Teleservice engineering tool
establishes a connection with the
machine or plant, and has at its disposalthe well-known functionality of STEP 7,
Drive ES, SIMOTION SCOUT and the
diagnostic tools. Teleservice functions
just as though you were actually at the
machine or in the plant. No additional
PC/PG is required.
Today, cross-network communication andworldwide communication are based on
TCP/IP. This Standard is used in both local
Ethernet network and on the Internet or
intranet, simplifying communication and
system interfacing.
Communication using information techno-
logy (Web, e-mail) are becoming increasingly
important in the automation world.
Communications processors transmit
event-controlled messages over IT
communication pathways by e-mail to
both local and global recipients. They areable to provide simple visualization using
Web technology and file processing (FTP):

Network performance
The differences in the performance
capabilities of multi-point interface,
PROFIBUS and Industrial Ethernet depend
on certain marginal conditions, such as
the number of nodes or the length of the
data frames.
One important marginal condition is the
required network access time, which is
the length of time a node must wait
before it can send a frame. The shorter
the network access time, the more the
networks differ in their performance.At 100 Mbit/s, Industrial Ethernet can
send 150 times the number of frames that
MPI can send in a given amount of time.
New technologies, used in combination,
can enhance Industrial Ethernet's
performance by a factor of 50 or more.
These technologies are:
� Fast Ethernet with 100 Mbit/s:
Frames are transported much faster,
and therefore reserve the bus for a
much shorter period of time.
� Full Duplex excludes collisions; the
data throughput increases enormously,
since the usual retries are unnecessary.
Between two stations, data can be sent
and received at the same time. The
data throughput over a Full Duplex Fast
Ethernet connection thus increases to
200 Mbit/s.
� Switching enables parallel
communication. Dividing a network
into segments using a switch off-loads
that network. Local data traffic in each
segment is completely independent ofthe traffic in other segments, making
it possible for several frames to be in
transport at the same time.
Data communication
Network performance and capacity
The performance enhancement
therefore stems from the fact that
multiple frames are underway at the
same time.
� Autosensing is the term used for
network nodes (data terminals and
network components) which can
automatically detect the transmission
rate of a signal (10 Mbit/s or 100Mbit/s) and support autonegotiation
(the configuration protocol for Fast
Ethernet).

The decision as to whetherto use multi-point interface
(MPI), PROFIBUS or IndustrialEthernet for datacommunication dependsmainly on requirementsrelating to network size,amount of data, number ofnodes and networkexpandability.
Here is a list of automation systems which can beinterfaced to the relevant networks and implementdata communication.
The typical number of nodes cites empirical valuesfrom many applications.
A factor important to network performance is theamount of data per frame. The worse the networkperformance, the shorter the frames should be inorder to prevent a single node from usurping the
available performance capacity. If long frames, e.g.program blocks or data blocks, have to betransmitted, they are first segmented.
Electrically, local networks can be extended to thelimits defined in the Standards. The use of opticalcomponents makes it possible to bridge longerdistances without violating the Standards, but the
configuration rules regarding execution time mustbe observed.
The way the cables between the nodes are laid isreferred to as topology.
Network operation requires that certainspecifications (e.g. addresses) be made by thestations in the network. In Industrial Ethernetnetworks, all parameters except the station addressare preset, enabling easy expansion. No busparameters are required. Flexibility is attainedthrough the use of the appropriate networkcomponents.
By making appropriate settings (e.g. network speed,monitoring times), PROFIBUS can be adapted to therequired network size, number of nodes, and timeresponse.The settings themselves can be easily made usingthe available configuring tools.MPI has default settings for all parameters, but someof these can be changed.
A number of basic communication functions areavailable on all the networks for the purpose ofuniformity.S5-compatible communication (SEND/RECEIVE)enables communication between SIMATIC S5 andSIMATIC S7 or a PC.
The PROFInet communication services are used fordata interchange between PROFInet devices, andare configured graphically using the vendor-independent SIMATIC iMAP engineering tool.
In a system such as SIMATIC S7, for example,additional performance capabilities can be imple-mented through the use of auxiliary components.
This is the reason why e.g. SIMATIC S5s, S7s andPCs can be interfaced to PROFIBUS and IndustrialEthernet using communications processors (CPs).

High-availability communication and redundancy
Process or field communication
Production plants are designed and calcu-
lated for around-the-clock shifts. When a
plant fails, the results are cost-intensive
downtimes, high re-start costs, and the loss
of valuable materials. Redundant control
systems such as the SIMATIC S7-H system
protect against such failures.
High-availability systems
The S7-400H is a high-availability
programmable controller. Handling,
programming, configuring and
communication are the same as forstandard systems.
Depending on the network topology,
redundant communication links are created
which become automatically available,
without loss of data, in the event of a
problem. The I/O are interfaced by means
of redundant PROFIBUS DP lines.
Redundant networks
S7-REDCONNECT ensures problem-free
communication between PC applications
(such as WinCC®) and the S7-400H over
redundant networks. PC applications whichalready use S7 communication (e.g. over
the OPC interface) may continue to be used
without any modifications. Industrial
Ethernet networks and PROFIBUS networks
can be set up as redundant networks with
OSM®, ESM® and OLM®. Thanks to ring
topology, the network continues to function
when one transmission path fails; failure
of a network component affects only the
nodes in that segment.

The "PROFIsafe" protocol profile, developedfor PROFIBUS DP, is used for communication
between a fail-safe S7 CPU and the fail-
safe signal module.
PROFIsafe features
PROFIsafe was the first communication
standard based on IEC 61508 to allow
standard communication and fail-safe
communication on the same bus. With SIL
3 (Safety Integrity Level 3), Category 4
(EN 954-1), it fulfills the highest demands
for the production and process industries,
and with the PA version (IEC 61158-2),PROFIBUS DP expands the integrated
distributed automation into the process
world. PROFIsafe thus supports the different
communication requirements of both the
production and process industries.
PROFIsafe functionality
PROFIsafe counters the possibility of
transmission errors due to problems such
as address falsification, loss, delay, etc. with
four different measures:
� Sequential numbering of the PROFIsafe
data
� Time monitoring
� "Password"-based authenticity
monitoring and
� An optimized version of CRC.
Using slave nodes, fail-safe encoder signals
from a PROFIBUS station are transmitted
to the fail-safe CPU. When these encoder
signals have been logically gated, an
appropriate output signal is transmitted to
a fail-safe PROFIBUS slave. Single-channel
transmission is used, and there is no
redundant transmission path.
Fail-safe communication
The fail-safe SIMATIC
components are part of Safety
Integrated, the Siemens
safety program based on
SIGUARD®, SIMATIC® and
SINUMERIK® / SIMODRIVE®
products. The PROFIsafe
protocol profile is used for fail-
safe communication on the
PROFIBUS.

Network interfaces between IndustrialEthernet, PROFIBUS, AS-Interface and EIB
are implemented through links,
programmable controllers (PLCs) or PCs.
In the latter two cases, integrated
interfaces and communications
processors (CPs) can be used to interface
networks. When a link is used to
implement a network interface, the data
are forwarded without changes of any
kind from one network to the other. The
DP/EIB Link, the DP/AS-Interface Link or
the IE/PB Link can be used as network
interface between EIB, AS-i, PROFIBUS
and Industrial Ethernet networks.
When PLCs such as SIMATIC S7-200,
S7-300 or S7-400 are used, data are
exchanged between the networks via
communications processors or integrated
interfaces. The data are preprocessed
using a controller (PLC or PC-based)
before being forwarded to the other
network.
PROFInet network interface with
Proxy functionality
PROFIBUS segments can be interfaced to
Industrial Ethernet by means of devices
with a representative function, so-called
PROFInet proxies.
This can be done using a solution
involving SIMATIC WinAC PN or via a
SIMATIC NET IE/PB Link.
This allows all standard PROFIBUS slaves
to be used without any changes for
Component based Automation.

AS-Interface
One feature of AS-Interface technology
is the use of a common two-wire cable
for data transmission and for the
distribution of auxiliary power to the
sensors/actuators. For this purpose, an
AS-Interface power supply unit is used
which fulfills the requirements of the
AS-Interface transmission method.
The mechanically coded and therefore
non-interchangeable AS-Interface profiled
cable is available for wiring purposes. The
repeater/extender is used to extend anAS-Interface segment.
PROFIBUS
For PROFIBUS, different transmission
media are available for a wide variety of
applications.
Electrical data transmission
The standard solution for this form of
data transmission is a shielded, twisted
pair cable with circular cross section.
These cables are available with PE or PUR
sheath, in a halogen-free version,
designed for underground installation or
as dragline, or in a special version for usein hazardous areas.
The PROFIBUS FastConnect® system (FC)
allows the PROFIBUS copper cables to be
prepared quickly and easily on site.
Optical data transmission
This solution is based on fiber-optics.
The FO cables are available with glass or
plastic fibers for indoor or outdoor use,
in a dragline version, and in a halogen-
free version.
Wireless data transmission
This form of transmission is based on
ILMs (Infrared Link Modules) with a reach
of 15 meters.
Industrial Ethernet
Electrical data transmission
� FC twisted pair
The FC twisted pair cabling system is
ideal for structured cabling in the plant
itself. The FastConnect(FC) connection
system for Industrial Ethernet not only
"industrializes" the structured cabling
system from the office area for use in
the plant. FastConnect cables can also
be prepared extremely quickly right
on site, thus making standard RJ45
cabling technology available in an
industry-standard version suitable for
structured cabling (patch, patchfield,
interior, outlet, service cabling).
Thanks to integrated insulation
displacement contacts (such as ELS
TP40), a connection is possible between
two nodes up to 100 meters apart using
FC TP cables without additional patching.
If electrical isolation and EMC protection
are the primary concerns, however, then
optical data transmission would be the
right solution.
Optical data transmission
� Glass fibers
The optimum technology, even for
setting up redundant ring networks.
Futuristic fiber-optics cables, which are
completely impervious to electromag-
netic interference, are used as trans-
mission medium. These cables are
also completely free from potential
dependencies. The advantage:
absolutely no need to invest in
expensive equipotential bonding.
Wireless data transmission
To allow wireless data transmission, a
local radio network for wireless
communication can be set up with just
an Access Point, such as RLM, and a radio
card, e.g. the CP 1515.
These transmission media can also
be used in any combination.

Totally Integrated Automation
with Component based Automation
The savings add up
Everything needed to automate is part of
the modular TIA system. Every single
device or system is of the highest quality
and performance, and would be worth
the investment even without being a
member of the TIA club.
To top it off, there is only one sales
contact, one ordering address, and
support is first-hand and from a single
source.
The savings really add up when TIA
includes IT, and when you add trainingand on-the-job training, configuring and
programming, commissioning, service,
maintenance, spare parts warehousing,
etc., etc., etc.
Open to the office world, fit for the
Internet.
The future is already a reality.
From the management level to the f ield
level, the combination of TIA and SIMATIC
IT means the communication is integrated
and the most suitable bus is available for
every application � Industrial Ethernet,PROFIBUS with AS-Interface as its
extended arm (for interfacing switching
and installation technology), EIB (for
integrating building services automation).
All I/Os, whether central or distributed, is
configured the same way.
TIA utilizes open, internationally
recognized communication standards,
just like the office world does, making it
possible to use Internet technologies for
automation. Controller information can
be requested using popular browsers,
making it possible to operate and monitorentire plants.
OPC is the standard interface for
accessing process data, and makes the
configuration of simple links to all PC-
based automation systems, as well as to
office applications, extremely easy �
wherever they may be, Internet
technologies enable remote plant
operation and plant monitoring. Thanks
to PROFIBUS, TIA is open to anexceptionally wide range of field devices.
The bus can even be used for fail-safe
applications and drive synchronization.
Even in the future.
Now and in future, TIA is open for new
technologies, new tools and partners,
not only in the world of automation but
in the IT communication network.
To make this possible, the strategy was
expanded to include an MES concept
and SIMATIC IT. The resulting strategy
enables improved coordination ofbusiness and production processes.
Component based Automation with
PROFInet
Component based Automation is the TIA
concept for modular plant and machine
construction. Technological
modularization is a reliable concept for
shortening implementation and
commissioning times in the plant and
machine construction industry.
If distributed intelligence is used, that is
to say, programmable field devices, drives
and I/Os, mechanical modularization can
be systematically extended to include the
automation solution.
Component based Automation utilizes
software component technology, which
makes the use of distributed intelligence
much simpler.
The new SIMATIC iMap engineering
software, which is designed for plant-
wide, cross-vendor use, replaces the high-
overhead programming of communi-
cation relationships between intelligent
devices with simple graphical configuring.
Component based Automation utilizes
the PROFInet standard from PROFIBUS
International.
PROFInet defines an engineering model
for distributed automation solutions and
a model for integrated communication
via PROFIBUS and Industrial Ethernet with
IT standards.

PROFInet
PROFInet takes the following aspects intoaccount, which are being worked on by
PROFIBUS International workgroups:
� Installation engineering with
industrial-standard connectors and
network components, including design
and installation guidelines
� Network administration (device
address assignment)
� Communication between
programmable controllers in
distributed systems (distributed
intelligence)
� Communication between distributed
field devices, such as I/O and drives
� Real-time communication for the high-
performance and deterministic
interchange of process data, even in
isochrone drive control systems in
motion control applications
� Remote diagnostics and network
diagnostics using reliable IT standards
such as WEB and SNMP
� Gradual integration of field-proven
PROFIBUS application profiles, such as
PROFIsafe
PROFInet is the integrated solution for
all communication requirements in
industrial automation, and combines on
a graduated basis the knowledge gained
from PROFIBUS and Industrial Ethernet.
� Stage 1 of PROFInet enables
implementation of distributed
automation structures.
� Stage 2 of PROFInet is concerned with
the interfacing of distributed field
devices to Ethernet and improving real-
time functionality on the Ethernet.
� In stage 3, PROFInet will enable
isochrone interfacing of controllers
and drives to the Ethernet via
Isochrone Realtime (motion control).
In contrast to the Office world, the use
of Ethernet in automation places higher
as well as special demands on the
components in industrial environments,
for example on
� Industrial-standard installation
engineering (connectors, cables)
� Higher availability
� Fast response times
(real-time capability)
� Network administration and
diagnostics
� Interfacing of existing fieldbus
applications and fieldbus devices in
Ethernet-based plants
The answer to the demands on an
Ethernet-based automation network is

It is becoming increasingly important forcompanies to coordinate business and
production processes and to optimize the
value-added chain of company and
individual plants alike. The challenges of
today are the optimization of global
operating costs and the improvement of
a concern's manufacturing flexibility.
In order for companies to be able to
improve their processes and remain
competitive, they have been
concentrating their investments for the
past several decades on local PLCs and,on the next higher level, on Scada
systems for the visualization of plant
processes.
Based on today's and tomorrow's markets,
Siemens developed a new MES procedure
which permits companies to coordinate
their business and production processes
in the plant, the company and the supply
chain while integrating and saving earlier
IT investments.
SIMATIC IT combines a stable standard
product which can get by with fewer
updates and permits adaptation on
specific manufacturing processes. By
carrying out "implied" product controls
(coordination of functionality) "explicitly",
they become less complex, less specific,
and subject to fewer modifications. This
makes them easier for other companies
or industrial sectors to use and easier to
adapt to specific manufacturing processes
and to modifications in that process. The
concept is based on an architecture which
combines model (explicit controls) and
components (functionality).
SIMATIC IT
SIMATIC IT is an MES concept, andconsists of cross-sector MES basic
functionality and a wide variety of
components which add specific
functionality. SIMATIC IT conforms to the
ISA S95 Standard, the focus of which is
not only on different functionalities, but
also on the processes and the workflow
required for a successful company.
SIMATIC IT Framework contains
modelling capabilities for plant
configurations and for production
models. It also contains basic IT services.
The explicit controls are described in
detail in SIMATIC IT Framework.
SIMATIC IT Components contain the
basic MES functionality required in thevarious industrial sectors as well as other
industry-wide and industry-specific
components according to functionality
and application. Examples are labor
management/quality management,
central product specifications
management, and plant performance
analysis.
The MES concept from Siemens A&D AS
MES is contained in the SIMATIC IT
product family, and is suitable for
seamless vertical and horizontal
integration in Totally Integrated
Automation.

Java is a platform-independent object-oriented programming language
similar to C++. The Java compiler, however, does not generate machine
code, but rather a byte code which must be interpreted. This is done with
the aid of the so-called Java Virtual Machine.
Local network
The master controls data transmission on the bus. Only one node may
be the master.
