The bus systems AS-Interface andPROFIBUS are used for data exchange upto the field area. These use the process orfield communication for data transmissionin order to link actuators and sensors to acontrol system.Industrial Ethernet offers industry-capablecommunications components which canbe used to set up both electrical networks
and optical networks.Thanks to the switching technology theranges are virtually limitless. In addition,Industrial Ethernet offers the option ofmobile communications, which can beseamlessly integrated into your networkstructure. As a result, information isreadily available anywhere and at anytime, and mobile access to theIntranet/Internet is made possible.
Industrial Ethernet uses data communica-tion to exchange data up to the field area.It is used between either two automationdevices or between one automationdevice and intelligent communicationpartners (PC, computer etc.).
PROFInet-capable productsAt Siemens, PROFInet is used for the
implementation of Component basedAutomation. This allows the advantagesof component technology, which arealready established in the software world,to be exploited for modular design ofinstallations and machines. In this wayexceptional productivity gains can beachieved in engineering and during com-missioning.

Fig. 2 Solution options with Industrial Ethernet
With Industrial Ethernet it is possible tobuild up large and powerful redundantnetworks.Components which are designed
specifically for industry enableproblem-free data exchange over longdistances.
Accordingly, robust network componentsform the backbone of industrial communi-cation for a multitude of applications, e.g.electrical or optical components in linear,
ring or star layouts, with 10 or 100 Mbit/s.The connections of the active componentson the network are implemented using
communications processors which,depending on the target system, are avail-able in different designs, performanceclasses and for different applications.
Industrial Ethernet with its universallyapplicable SIMATIC NET components isused in a wide variety of industrial fields.
Sample applications from themanufacturing industry and theprocess industry
Automotive manufacturingIn automotive manufacturing it is possibleto implement production lines with vari-able speeds or installation control systemsfor use while the production line is in
operation. Flexible controls need to beavailable for many of the variables in orderto ensure that production is uninter-rupted.In this context plant availability is becom-ing increasingly more important.Downtimes for repairs are usually moreexpensive than suitable monitoring sys-tems which monitor installations for wearand possible faults.Using powerful communication compo-nents, it is possible, for example, to quicklylocate and indicate faults.

Food and beveragesThe flow of materials from the initial deliv-ery e.g. of potatoes through the sort-ing and storage processes right up to thepoint where the goods are taken out ofstorage and the packaged items are trans-ported is programmed in advance, andcan be modified on the master computer ifthe capacity utilized or the requirementschange.The operating states and aggregates ofconveyor systems can be monitored andinfluenced just as easily as the filling ofsilos. In this case the co-ordination ofdifferent sorting installations is just asmuch a commununications duty as theautomatic individual ventilation of thepotatoes.
Building automationBuilding automation is already well-estab-lished in multi-story car parks. Free spacesare already indicated at the entrance tothe car park and arrows are used to showthe motorist the shortest route to a freespace. A contact-free sensor mounted onthe ceiling operates as a parking spacemonitor, regularly checking the space by
means of ultrasound. An alarm is raised inthe control center if somebody drives thewrong way up an access ramp or if a linestarts to form.A high-performance communications pro-cessor collects and co-ordinates the data,and then visualizes them for example on acomputer.
Waste watersThe purification of waste water requiresspecial properties for automation compo-nents and communications system suchas suitability for use in given temperatureranges, resistance to EMC disturbances or
rapid messaging in the event of a fault.Filter lines, pumps and measuring devicescan be monitored and controlled from thecontrol office to ensure a smooth flow ofprocesses in the installation.High-performance communications reli-ably convey the corresponding data fromthe sensors to the control office.There, these data can for example be visu-alized and controlled by using a computer.

Networks with switchingtechnologySwitched Industrial Networks can be builtup either electrically or optically, both in alinear structure as well as in redundantring structures.The structure incorporates either anOSM(Optical Switch Module) or an ESM(Electrical Switch Module). Transmissionsbetween the modules take place on fiberoptic cables for OSM or TP/ITP cables forESM. Terminal devices and networksegments are connected using TP or ITPlines.The expansion capabilities of switchednetworks are virtually limitless. Signal runtimes need to be taken into account fromdistances of 150 km.The switching functionality has decisiveadvantages: It is possible to form subnetworks and
network segments. The data throughput and therefore the
network performance can besignificantly increased as a result ofstructuring the data traffic.
The network configuration rules areeasy to apply.
Network topologies with 50 OSMs andan overall range of up to 150 km areeasy to realize, with no need to takesignal run times into account.
Limitless expansion of the networkrange is possible by connectingindividual collision domains/subnetworks.
Switches allow existing networks to beexpanded easily and without retroactiveeffects.
Networks in a linear structure withswitching functionality
The Electrical Lean Switches (ELS) havebeen specially optimized for setting upIndustrial Ethernet networks with10/100 Mbit/s in a linear structure in thefield area. In addition to switchingtechnology, they are equipped withintegrated FastConnect (FC) connectiontechnology for quick and easy connectionof the FC lines (see page 10).The ELS are designed for use in a switch-ing cabinet.

Redundancy in the networkIt is vital for industrial applications that thenetwork reconfiguration time is as fast aspossible after a fault, otherwise, theconnected terminal devices willdisconnect their logical communicationsconnections.Redundant networks increase the overallsecurity and reduce installation downtimes.In order to achieve the extremely fastreaction times which are required,SIMATIC NET uses a specially developed
technique to control the standby function.This ensures that a network can bereconfigured to a functioning networkinfrastructure within fractions of asecond.
Standby through softwareThe standby software S7-REDCONNECTcan be used to link PCs to the high-avail-ability SIMATIC S7-H system. As a result,SIMATIC S7-H redundant systems protectagainst downtimes of the installation.In the event of failure of a subsystem orbreakage of a wire, the system switchesover to the backup system or backup net-work (dual bus, redundant ring), whichallows it to keep the communicationsintact.

The network component ELM (ElectricalLink Module) can be used to integrateexisting 10 Mbit/s triaxial networkswithout any problems into new 100 Mbit/snetworks with switching technology.Expansion with switching technologyoffers the following advantages: You can continue to use your
knowledge of existing technology. There is no need to learn a completely
new technology. The fast switching technology is
available for immediate efficient use.
Industrial Ethernet offers the option of astep-by-step migration from 10 Mbit/s tothe 100 Mbit/s technology.
Existing networks can be integrated andexpanded step-by-step.
In addition, ELM enables the connectionof up to three terminal devices using atwisted pair interface to an existing triaxialnetwork or to an industrial twisted pairnetwork.

Industrial Ethernet ESMThe ESM (Electrical Switch Module)enables switched networks with100 Mbit/s to be built up cost-effectively.A decoupling of loads and therefore anincrease in network performance can beachieved in existing networks throughsegmentation (division of a network intosubnetworks/segments) and connectionof these segments to an ESM.The standby manager which is integratedinto the ESM permits the building ofredundant Industrial Ethernet ring
structures with switching technology andfast media redundancy (max.reconfiguration time 0.3 seconds).Electrical rings are set up with 2 twistedpair ports of the ESM. The data transferrate in the ring is 100 Mbit/s, and up to50 ESMs can be used in each ring.In addition to the 2 ring ports, the ESM hasa further 6 ports (optionally either with ITPor RJ45 interface), to which both terminaldevices and network segments can beconnected.Several rings can be connected togetherredundantly using the integrated standbyfunction.Three options are available for signalingerrors: using indicator contacts using SNMP (traps) by e-mailThe network topology can be easilyadapted with ESM to the plant structure.The following network structures andresulting combinations can be realized: Linear structures and star structures

Optical network componentsIndustrial Ethernet OMC and OSM
Industrial Ethernet OMCThe Industrial Ethernet OMC TP11 andOMC TP11-LD (Optical Media Converter)enable the targeted use of fiber opticcables in Industrial Ethernet networks.100 Mbit/s full duplex twisted pairinterfaces of terminal devices or networkcomponents are converted to fiber opticcable interfaces with the aid of OMC. Thisallows for example the followingapplications to be realized: Integration of a single remote terminal
device or a remote subnetwork using
fiber optic cable into an IndustrialEthernet network.The maximum length for the fiber opticcable is: with multimode fiber optic cable and
OMC TP11 3 km or with OMC TP11-LD and monomode
fiber optic cable 26 km. Integration of a stretch of fiber opticcable into a redundant ring with ESM byconnecting two OMCs and fiber opticcables in between
Equipotential bonding measures orlightning protection devices are notrequired when using OMC and fiberoptic cables.
OMC pass on error states detected at oneof the ports to the other port. Thereforethey can be integrated into redundantrings or redundant connecting stretchesbetween rings (connection of OMC at thecoupling or ring ports of OSM TP/ESM).The ability of the media converters tofunction properly can be monitored viathe indicator contact.
Industrial Ethernet OSMThe OSMs (Optical Switch Modules)enable cost-effective building of switchednetworks with 100 Mbit/s. A decoupling ofloads and therefore an increase in net-work performance can be achieved inexisting networks through segmentation(division of a network into subnetworks/segments) and connection of these seg-ments to an OSM. The standby managerwhich is integrated into the OSM permitsthe building of redundant IndustrialEthernet ring structures with switchingtechnology and fast media redundancy(max. reconfiguration time 0.3 seconds).

Fig. 25: Communications processors for SIMATIC
The communications processors ofSIMATIC NET can be used for applicationsat the field level, in process automation orfor wireless communications.Effectiveness and efficiency are vital forthe solution concepts for plant compo-nents and automation tasks. Accordingly,the requirements for communicationperformance are very high in terms of thedata transfer rate.The communications processors offer aconstant data throughput as a result oftheir pre-processing of the protocol. They
realize fast reaction times with stable highlevels and avoid fluctuating levels of com-munications performance.The CPs ease the strain on the terminaldevice in terms of communications tasksand only take up very few resources there.
PLC as an element ofcommunication
Programmable controllers (PLCs) play acentral role in the world of automation.And in the process the industrialcommunications represent the nervefibers. The SIMATIC NET PLC-CPs play a keyrole in industrial communications.
They offer the following advantages: CPs for all formats of SIMATIC,e.g. SIMATIC S7-300/-400.
Thanks to the open communicationswith standards the SIMATIC cancommunicate with every other device.
SIMATIC NET increases the availability ofplant sections which are networkedtogether in a modular layout, in the sameway that electrical power supplies are alsoimplemented in individual electricalcircuits.SIMATIC S7 controls can be integrated viathe standard protocols TCP/IP, HTTP, SMTP
and FTP in higher-level software systemslike MES (Manufacturing ExecutionSystem) and MIS (ManagementInformation System).This is even simpler with SIMATIC NETproducts for Windows PCs, which offer anOPC interface and are embedded in theSIMATIC engineering system.

Potential applications for communicationsCommunications processors for SIMATIC S7
Different communications processorsare available for connecting to theSIMATIC S7. The design of these proces-sors differs according to their targetsystems, i.e. there are different ones forfor SIMATIC S7-200, SIMATIC S7-300 andSIMATIC S7-400.The communications processors are alldesigned for use in harsh industrialenvironments and can be usedthroughout a wide temperature range.In addition they are also certified for shipbuilding (ABS) to enable their use on shipsor offshore units. They are equipped withRJ45 connection technology and cantherefore be integrated into theindustry-suitable cabling system ofSIMATIC NET. The data transfer rate of 10and 100 Mbit/s permits fast datatransmissions with large quantities ofdata.The CPs are equipped with S7communication as standard; CP 243-1,CP 343-1 and CP 443-1 are standardprocessors.In addition to the standard processes,SIMATIC NET also offers communicationsprocessors with expanded functions
which open up a variety of differentopportunities. CP 343-1 IT and CP 443-1 IT with IT
functionality plus CP 343-1 PN for use with
PROFInet functionality.
CP 243-1 for S7-200
The CP 243-1 forms the connection toSIMATIC S7-200 and enables a dataexchange with the S7-200 and S7-300 orS7-400 controls using Industrial Ethernet.The CP can communicate through up to 8connections to other Ethernet users, whe-reby the CP can play the role of both Clientand Server.PC applications can access the data of aS7-200 with CP 243-1 using the standardi-zed, open and manufacturer-independentOPC interface. The software packageSOFTNET-S7 is required to access the data.In this way the process data can be visua-lized, archived or further processed withthe aid of a PC, e.g. with PC applicationslike WinCC or WinAC.
