Sensors for production engineeringOptimum solutions for all tasks

Sensors play an important role inmany machines and plants, forexample:· Detecting the position of an

objects· Detecting and checking the shape

of objects· Detecting contrast and markers

invisible to the naked eye· Identifying objects, with mobile

data memories as well· Reliable occupational safety for

man and machine

Examples of these tasks are abun-dant in all areas of industry:· In conveyor technology, countless

contactless sensors control com-plex processes.

· In assembly lines, mobile datamemories accompany productsthrough the assembly stages.

· In industrial production, machinevision systems check products forrejects or packaging for intact-ness.

· In automated processes, effectiveaccident prevention and the pro-tection of persons have maximumpriority. Contactless safety sensors– such as light barriers, light arraysand laser scanners – reliably limitaccess to dangerous areas.

· In transport logistics and trafficcontrol, sensors are used to iden-tify automobiles, even at great dis-tances, as well as containers, andto monitor main assembly lines.

SIMATIC Machine VisionIntroduction

The SIMATIC Machine Vision imageprocessing systems are designed forautomatic visual inspection andidentification of parts in productionprocesses:

ApplicationThe optical inspection and identifi-cation of products in productionprocesses is becoming an increas-ingly important topic as thedemands for quality and productionspeed increase. Arguments support-ing their use are clear:· Fewer rejects· Delivery of tested productsThese general requirements arespecified by DIN ISO 9000 and inproduct liability laws.Monotonous visual inspection oridentification by persons is expen-sive. At the same time, concentra-tion and mood are subject to naturalvariations.Furthermore, increasing cycle ratesmake checking by personnelincreasingly difficult. The use of an

image processing system is applica-ble here:· Automatic visual inspection dur-

ing quality assurance; the systemchecks objectively, rapidly andreliably the dimensions, contours,shapes, presence, correct assem-bly, position and completeness ofparts which can even be micro-scopically small.

· Automatic identification of partsusing shapes, dimensions,patterns, colors, codes and char-acters.

·

Automatic locating and reading ofdata matrix codes.

The SIMATIC Machine Vision range:· SIMATIC VS 110

The intelligent vision sensor forvisual form inspection of theshape of small parts.

· SIMATIC VS 120For rugged and fast object locat-ing using incident light proce-dure.

· SIMATIC VS 130For automatic locating and

reading of 2-D-Codes.

· SIMATIC VS 710 and ProVisionThe compact, general multi-pur-pose image processing system forautomatic inspection, productmonitoring and parts identification.

· SIMATIC VS 720 and SpectationThe general-purpose VS 720 sys-tems for increased speed and reso-lution, with additional color detec-tion and Ethernet connection.

Intelligent vision sensors from theVS 100 rangeThe intelligent vision sensors withapplication-specific image process-ing are complete packages

comprising: Sensor head, LED andevaluation device.

FunctionsThe following functions are com-mon to all devices of the VS 100range:· External triggering· Setting parameters and configur-

ing on the device or throughexternal controllers (IPC, Web Cli-ent, PLC)

· Simple linking using PROFIBUS DP(not with VS 110) or Ethernet

(not VS 110), serial interface (notVS 120)

· Live picture on PC during set-up· Output of fault patterns (not with

VS 110)· Pro Vision sensors are available in

several versions: with fixed focuslens and different image fieldsizes or with C/CS-mount lens con-nection for any image field sizes

Advantage of VS 100A decisive advantage of the visionsensors from the VS 100 range isthe commissioning by training :The operator need only place a goodunit in the correct position in frontof the camera. The system saves therequired parameters after pressingof a key, and can immediately com-mence working.This means that operators need nothave any image processing know-how, and that products can bechanged without delay.

SIMATIC VS 110 is supplied as a complete package with sensor head (camera),infrared illumination and processing unit.

SIMATIC Machine VisionVS 100 range

VS 110 vision sensorThe intelligent SIMATIC VS 110vision sensor optically inspects smallparts during material feeding forcorrect shape and position, and sig-nals faulty parts or incorrectly posi-tioned parts by means of an NOKsignal.It is possible to monitor e.g. bolts,screws, injection-moulded parts,small metal parts, chocolates etc.The following properties can bemonitored:· Checking according to object

type: is the object of the correcttype (differentiation of types)

· Checking according to correctlyoriented supply: two differentpositions can be trained andevaluated

· Checking for absence of damageand correct processing

Visual inspection is carried out withinfrared transmitted light. Theobject to be checked is locatedbetween the light source and thesensor, thus generating a shadowimage. The test can be started intwo manners, either externally, e.g.using a light barrier, or the VS 110vision sensor automatically recog-nizes an object in its image field(automatic triggering).The following units are examples ofthose which may be used to trans-port the parts:· Oscillating conveyors (spiral con-

veyor, linear conveyor), conveyorbelts

· Workpiece holder revolvingsystems

VS 120 vision sensorThe intelligent VS 120 vision sensorworks using incident light, i.e. in theideal case the light comes from thedirection of the camera.This means that not only the shapeand position of the test piece can be

recognized. Detection of patternson the surface permit additionalconclusions. For example, thecompleteness of printing can bechecked. This information can beused for evaluations, e.g. to controlsubsequent handling units.This information is provided by theVS 120 vision sensor together withthe position (with x/y coordinates,angle of rotation) via a PROFIBUS DPor serial interface to a PLC which inturn can control e.g. handlingequipment.

VS 130 vision sensor 2-dimensioncode readerThe main application of this intelli-gent vision sensor is the reading ofdata matrix codes according toECC200.The matrix can comprise up to72 x 72 dots depending on thequantity of data to be coded,corresponding to a data quantity of366 characters.The information density of thematrix is 100 times greater than thatof a barcode of identical size. Thismeans that more information canbe accommodated in the same area,or that the ID coding is possible onan extremely small area.The VS 130 vision sensor automati-cally finds the code in the imageeven under difficult conditions. Thesensor head need only be roughlypositioned so that the code is withinits image area. The rotational andtranslational positions are unimpor-tant. This provides the advantagethat only low demands are placed

on the mechanics of the conveyorsystem, permitting cost savings.Lasered, printed, stylus-marked ordrilled code is recognized on planeor slightly curved surfaces. Non-readable codes are separated by anNOK signal. The information of aread code can be· compared with the defined value

(digital output) or· passed on via PROFIBUS, a serial

or Ethernet interface to a PLCwhich then controls appropriatehandling equipment.

A quality test can be selected for theread code.

Advantages of the VS 130The vision sensor need not beparameterized for adaptation to dif-ferent carrier materials and types ofmarking. The sensor sets its ownparameters automatically, evenwhen reading the code. This resultsin a reliable reading function even indifficult conditions, e.g. with varia-tions in the marking quality.The HMI is Web-based, and there-fore executes on different systemswithout installation. Furthermore, itcan be incorporated into the WinCCstandard HMI.The vision sensor permits the user toexecute system backups, reloadsand software upgrades even inremote mode.The device concept supports remotemaintenance. To eliminate prob-lems, machine data (fault patterns)can be checked by the servicing andsupport team via e-mail or by directInternet/intranet access.

Sonar-BEROs

Using ultrasonic technology, theSonar-BEROs can recognize objectsof any constitution, i.e. also liquidsand powders, colored ortransparent.It is irrelevant whether the surface isrough or smooth, clean or contami-nated, wet or dry, glossy or mat.Sonar-BEROs are also extremely rug-ged, and insensitive to contamina-tion, vibration, ambient light andexternal sound.Sonar-BERO measure the propaga-tion time of the transmitted ultra-sound reflected by the object, andcan then calculate the distance tothe object. The Sonar-BERO canmeasure extremely small (3 cm) orextremely large distances (10 m)without problem.Measurement of the ultrasound iscarried out in different manners:· The compact range with integral

evaluation and adjustment on theSonar-BERO. These compactdevices are mainly for applica-tions where the parameters need

only be set once during commis-sioning, and where modificationsare carried out by experts. TheSONPROG software permitsextremely simple adjustment forthe object and switching range(e.g. minimum level).

· The Sonar sensors for recordingfast movements under difficultambient conditions, e.g. steam,transparent materials, sprayingwith water etc.

Advantages of Sonar-BEROsThe decisive advantages of Sonar-BEROs are:· Contactless detection at distance

from 3 cm to 10 m.· Insensitive to contamination (as

result of vibrating ultrasonic con-verter), vibration, ambient light ornoise.

· Color-independent, also suitablefor transparent objects.

· Temperature compensation:measurement of distance withaccuracy of 1.5% from -25 °C to+70 °C.

· Simple and fast parameterizationby PC via SONPROG interface.

· Different frequency values can

be programmed for each Sonar-BERO.

One single Sonar-BERO can thushandle the tasks of several opticalsensors.

SIGUARD safety engineeringLight curtains and arrays

Light curtains and arrays are active,opto-electronic safety units to pro-tect areas in automated processes.SIGUARD light curtains protect per-sons from entering non-protectedareas (e.g. finger and hand protec-tion, access protection, or horizon-tal definition of danger areas).The evaluation units incorporate thelight curtain signals according toCategories 2 and 4 of EN 954-1 intothe machine control, thus offering:· Start-up/restart blocking· Contactor checking· Muting· Cycle control· Diagnostics functions using PC

Multi-scan modeIn multi-scan mode, the plant is onlyswitched off if the light beams areinterrupted during a definable num-ber of scans. This increases plantavailability and the immunity tointerferences from ambient light.

Start-up/restart blocking

This prevents immediate restartingof the plant following clearance ofthe protected area, and is obligatoryfor producing access control zones.

Contactor checkingFor direct monitoring of con-tactors, relays or valves con-nected in series with the lightcurtain. Switching elementswith positive-action feedbackcontacts are a prerequisite.

Host/guest combinationBy combining light curtains, itis possible to lengthen the opti-cal axis and thus the height ofthe protected area. It is thenpossible to provide effectiveprotection in the horizontaland vertical directions.

Blanking functionsThree different blanking functionscan be selected depending on theapplication:· Fixed blanking

For objects which are perma-nently within the protected areaand are not moved. The signalstriggered by these objects areignored, and the object is sup-pressed.

· Floating blankingSuppresses objects which are per-manently within the protectedarea and which can also movethere.

· Reduced resolutionFor objects which can movewithin the protected area and alsooutside it.

Muting functionsCoupled with other sensors, it is pos-sible to implement temporary,safety-related suppression of theprotective function, e.g. when trans-porting material through the pro-

tected area.

SIGUARD light curtains offer 4modes:· 4-sensor sequential muting

Used with objects which arealways the same size and if suffi-cient space is available.

· 2-sensor parallel mutingUsed for objects of different sizesand with little space. Two mutingsensors are used whose beamscross behind the protected area.

· 3-sensor directional mutingThe 3-sensor directional mutinghas a similar design to the 2-sen-sor muting. Objects can only passthrough the light curtain in onedirection.

· 4-sensor parallel mutingUsed with very small objects, andrequires even less space than theversion with 2 parallel sensors.

Cycle controlIn addition to the safety functions,SIGUARD light curtains can also beused for machine controls, e.g.when inserting and removing work-

pieces.

Laser scanners

Irrespective of the automated sec-tor, maximum protection for manand machine has top priority. Ofprime importance is maximumsafety for all involved in the produc-tion or process. In addition, maxi-mum possible plant availability mustbe permanently guaranteed.

These requirements can be fully sat-isfied by the SIGUARD LS4 laserscanner from the Safety Integratedrange.

Whether stationary machines ormobile systems such as automaticguided vehicles – SIGUARD laserscanners provide perfect safeguard-ing of danger areas in almost anyworking environment, up to Cate-gory 3 according to EN 954-1. Up tofour pairs of protection and warningareas for persons and objects can befreely selected during operation.These can be simply programmedusing a PC or laptop, and can there-

fore be rapidly and flexibly adaptedto new requirements. As optical dis-tance sensors, SIGUARD laser scan-ners detect all movements within a190° working environment. Theemission of laser pulses and subse-quent evaluation of each individuallight reflection means you haveeverything under control, and canreact rapidly and exactly in poten-tially dangerous situations.

In addition to conventional interfac-ing, the new versions of the

SIGUARD laser scanners with com-munications capability can be linkedreliably and conveniently via inte-gral interfaces to the AS-InterfaceSafety at Work and PROFIBUS withthe PROFIsafe profile.

The common transmission of safety-related and standard data permitsfail-safe implementation of uniformcommunication via standard field-buses. The advantages of a businterface are therefore also availablefor SIGUARD laser scanners.

MOBY identification systemsMOBY D, E, F

Identification systems must be ade-quate for many and often very indi-vidual requirements. Low-priceSmartLabels are required for large-volume logistics applications, butrugged data storage is necessary forassembly lines. In the automotiveindustry, these mobile data memo-ries (MDS) must, above all, be heat-resistant, and in traffic control andtransport logistics, "long range" datamemories are an indispensablecomponent.No matter what your requirementsmay be: MOBY, the clever electronicidentification systems fromSiemens, are always the perfectsolution. They provide reliable, fastand economical identification, areimpervious to dirt and air pollutants,and store data right on the product.This way, it is possible to not onlycontrol material flow, but also tooptimize it.

Function principle of MOBY MOBY basically consists of the fol-lowing compatible devices:· Mobile Data memories (MDS)

Mobile data memories (MDS ortag/transponder) are attached tothe product, product carrier orpackaging. They are written onwithout contact. The memories

contain all application-specificdata. Up to 32 KB data can bestored, and edited or read backwhen required.

· Read/write units (SLG/SIM)handle the fast and secure datatransmission to the mobile datamemories. Data is transferredinductively (electromagnetically)through an electromagnetic fieldor by radio. A serial connectioncouples them to ASM and tohigher level systems (PLC, PC, ...).

· Interfaces (ASM)Interfaces (ASM) integrate theidentification systems MOBY intoSIMATIC, SINUMERIK, and effectthe connection to PROFIBUS,TCP/IP1) , PC and other systems.Once they are fed with appropri-ate parameters and data, theyhandle the data traffic autono-mously. Then the results and datais made available. Correspondingsoftware modules (FB/FC forSIMATIC, C libraries for PC runningunder Windows) let you incorpo-rate MOBY into your applicationeffortlessly and fast.

MOBY P innovationMOBY P supplements the productrange for assembly lines for simpleor complex applications. A particu-larly low-cost solution will soon beavailable: the first SLG with IQ-Senseinterface for reading/writing smallquantities of data. Further compo-nents will follow to satisfy highspeed and data quantity require-ments.

Advantages of MOBY Compared to other informationmedia, e.g. barcode, MOBY offers ahost of advantages:· Insensitive to temperature

changes and dirt· Long life cycle· Up to 32 KB can be stored directly

on the product· Re-usable· 100% secure data transmission

RF identification systems MOBYD, F, E for storage/logistics anddistributionMOBY DMOBY D is a new RF identificationsystem acc. to standard 15693 inthe 13.56 MHz range. The field ofapplication ranges from simpleidentification such as electronicbarcode substitution, barcodeextension or delivery note in a harshenvironment, through storage anddistribution logistics, all the way toproduct identification. Due to thelow cost of SmartLabels in high vol-ume applications and the ease withwhich they can be integrated intosystems, MOBY D is the ideal identi-fication system for the applicationsmentioned above. Depending onthe read/write distance, variousread/write devices are available.

MOBY E and FMOBY E and F have been used formany years in many applications inlogistics and distribution, e.g. wherecontainers have to be identifiedautomatically, reliably, fast andwithout contact. Different datamemories and read/write units with

integrated or separated antenna areavailable, depending on the require-ments (fixed code/EEPROM, size,ambient conditions, largerdistances, etc.).Typical areas of application include:· Parts identification for textiles

(e.g. rented clothes, hospital gar-ments) in laundries

· Logistics (identification of e.g.pallets, goods carriers, containers,etc.)

· Parts identification, for luggage,gas bottles, etc., in a logisticschain

· Goods distribution in open distri-bution chains

· Assembly lines (identification ofworkpieces, etc.)

MOBY I, U, R

RF Identification system forindustrial productionMOBY IThe MOBY I contactless identifica-tion system has been successfullyused in a wide range of applicationsworldwide for many years now. Ithas been specially designed for ap-plications in industrial production inwhich high demands are placed on· reliability· reading and writing in dynamic

mode· a high degree of protection· automatic identification.Different data memories andread/write units are availabledepending on the requirements(EEPROM/FRAM, size, ambient con-ditions, larger distances, etc.).The main applications for MOBY Iare:· Assembly lines (data memory is

attached to workpiece carrier).· Manufacturing processes (data

memory is attached e.g. toproduct carrier).

· Conveyor technology (data mem-ory is attached e.g. to overheadmonorail conveyor)

· Assembly lines in the automotiveindustry (e.g. heat-resistant datamemories)

RF Identification system forassembly lines, transportationMOBY UMOBY U is based on the new stan-dard ISO18000-4 and was designedfor international applicability. Itoffers multitag-capability and a con-tinuously adjustable range of up tothree meters. With these featuresMOBY U focuses on:· Main assembly lines in the auto-

motive industry (body-in-white,surface and installation)

· Vehicle identification/access con-trol in haulage companies, carparks, etc.

· Container-/freight carrier identifi-cation in transport logistics anddistribution.

By integrating UMTS/GSM technol-ogy all known noise inductions (e.g.overreach) were eliminated. Newfunctions, e.g. automatic selectionof free frequency channels(Frequency hopping), permit it tooptimally cooperate with other2.4 GHz systems like Wireless LAN or

Bluetooth.Rugged housing and power-savingcircuit engineering enable years ofmaintenance-free operation in eventhe most rugged productionenvironment.

Identification andlocalizationMOBY RMOBY R is a real-time localizationsystem that can identify objectswithin a range of up to 300 metersand an accuracy of 3 meters.The system can be used to localizeany object in real time and in allkinds of surroundings (e.g. materialboxes, containers, etc.) and even inlarge premises (e.g. airports, carrentals, automobile factories, etc.).

Areas of applications include,for example· Cars:

localizing, tracing· Containers: localizing, tracing,

theft protection· Access checks· Loading zone supervision· Trucks: localizing the trailer· Guiding cars· Material flow monitoring and

requests, e.g. in hospitals and

production linesAdditional informationMore details of MOBY identificationsystems are available in catalog"Identification Systems MOBY" KT 21or on the Internet:www.siemens. com /moby
