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.

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.

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.


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.

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

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.

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.

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):

Industrial Mobile Communication

This term is used for the industrial mobile

communication products for wireless

communication from SIMATIC NET.

Industrial Mobile Communication is based

on worldwide networks, such as WLAN

(to IEEE 802.11b), GSM or, in future,

UMTS. Thanks to enormous growth in

the diversity of information technology,

Industrial Mobile Communication is being

used with increasing frequency in the

automation world, making global

communication in automation

environments possible while at the same

time creating the possibility of problem-

free links to the planning and office

worlds through the following products:

� MOBIC® Internet Pad for wireless access

to intranet and Internet as well as Thin

Client applications

� The CP 1515® communications

processor and RLM Radio Link Modules

for setting up a wireless IEEE 802.11b

network and for linking mobile nodes

to that network.

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


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.

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

PROFInet, the open and innovative

communication standard from PROFIBUS

International.

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.

RLM Radio Link Module Access Point for setting up a local wireless LAN radio network to IEEE 802.11b

SFC System function calls System function calls integrated in the CPU operating system, e.g. timers

or block transfers

Slave The stations addressed by the master are referred to as slaves. Thecommunication relationship between stations on the bus is therefore

referred to as master-slave relationship.

Socket The Socket interface enables data communication with computers via

TCP/IP. Users can write their own programs using this interface, which is

popular and widely used in the PC and UNIX worlds. In the SIMATIC S7, the

SEND/RECEIVE blocks are used as access portal to TCP/IP.

S/R SEND/RECEIVE block Enables SIMATIC S7/C7 communication with other systems, SIMATIC S5s,

PGs and PCs via PROFIBUS and Industrial Ethernet.

Switching Simultaneous establishment of multiple connections between ports. These

connections are established dynamically and temporarily based on the data traffic.

TCP/IP Transport Control Protocol/ De facto standard;

Internet Protocol Protocol for worldwide communication over Ethernet.

Thin client The principle of Thin Client/Server Computing is based on the fundamental

physical separation of data.
