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 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.

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.

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.

CPs for S7-300 and S7-400

The CP 343-1 and CP 443-1 communicati-ons processors form the connection to theIndustrial Ethernet for the relevantSIMATIC S7. They are equipped with Auto-sensing (10/100 Mbit/s) with the opera-ting modes HDX (Half Duplex) and FDX(Full Duplex) with a connection for auto-matic detection of operating modes.

They offer universal connection possibili-ties for ITP, RJ45 and AUI as well as thecapability for processing several differentprotocols at the same time, e.g. ISO, TCPand UDP transport protocol (CP 343-1 PN:no ISO). The remaining communicationsservices like PG/OP communications andS5-compatible communications(SEND/RECEIVE) complete this area ofapplication in industrial environments.
