PROFIBUS‐DPbasics
ThisdescriptionprovidesinformationconcerningtheimplementationofthePROFIBUS‐DPtransmissionprotocolintheslave
modeinourdevices.Itshouldbenotedthattheextentofthefunctionsdescribedmightbelimitedaccordingtothedeviceor
application.Withprotocolconversionsinparticular,asarulefewerfunctionsareused!
Theprofilerequired
Thelinkbetweenthedecentralizedprocessoperationandthecentralcontrolviathecommunicationsystemtakesplacein
thelowesthierarchylevelonthefiledorprocessbus.Atthislevel,themainrequirementsareasimpleprotocoloperation
andshortdatatransmissiontimesforthecommunication.Thisensuresthefastestsystemreactiontimetothedynamic
statesoftheperipherals.Inadditiontotheclassicdataexchange,theacyclictransmissionofparameter,diagnosticand
configurationdatamustbepossible,withoutradicallyimpedingthereal‐timecapabilityofthebus.Thisistheonlywayto
guaranteetheachievementofgooddiagnosticsandsafeoperation.
Characteristics
ThemaintaskofPROFIBUS‐DPisthecyclictransmissionoftheprocessdatafromthecontrolsystemtotheperipheral
equipmentandviceversa.TheaccessprocedureusestheMaster‐Slaveprinciple.HereinthepollingoperationaMaster
communicateswithitsassignedslavedevicesoneaftertheotheronthebus.Adataexchangeisinitiatedbyarequest
telegramandendedbyanacknowledgementtelegramfromtheSlaveconcerned.So,eachSlaveonlybecomesactiveaftera
callfromtheMaster.Thisavoidsasimultaneousbusaccess.ThehybridaccessprocedureofPROFIBUSallowsacombined
operationofseveralbusmastersandevenamixedoperationofPROFIBUS‐DPandPROFIBUS‐FMSwithinabussection.
Howeverthepre‐requisitionforthisisthecorrectconfigurationofthebussystemandtheunambiguousassignmentofthe
SlavedevicestotheMasters.PROFIBUS‐DPdistinguishestwotypesofMaster.TheClass1Mastercarriesoutthecyclic
transmissionoftheoperatingdataandsuppliestheuserdata.TheClass1MastercanbeaddressedbyaClass2Masterusing
certainfunctions.DirectaccesstotheSlavesisnotpermitted.Thefunctionsarelimitedtosupportservicessuchasreading
thediagnosticinformationoftheslaves.AClass2Masteristhusalsounderstoodasaprogrammingordiagnosticdevice.
Protectivefunctions
PROFIBUS‐DPisequippedwithmanyprotectivefunctions.Theseensuresafefault‐freecommunicationnotonlyintheharsh
environmentofthedecentralisedperipheralequipment,butalsointhecaseofexternalinterferenceorthefailureofoneor
morestations.Wrongparametersettingsarerecognizeddirectly,inthatstationshavingthewrongparametersarenot
integratedintheoperatingdataexchange.
TheMasterrecordsthefailureofanystationandindicatesthistotheuserbymeansofageneraldiagnosticmessage.
AnybreakdowninthetransmissionpathisdetectedbytheSlavebymeansoftimemonitoringandleadstotheoutputsbeing
switchedoff.
EMVdisturbancesarevirtuallyfilteredoutbymeansofthedifferencesignal,thankstotheparticularlynoise‐immuneRS485
transmissionsystem.
Datatransmissionerrorsarerecognizedthankstoframeandcheck‐sumcontrolsandleadtotheretransmissionofthe
telegram.

2 Start-up Start-up
BeforeaPROFIBUS‐DPsystemcanbestartedup,uniquebusaddressesmustbeassignedtoallconnectedstations,including
theMastersystem.Thisistheonlywaytoensureunambiguousaddressingonthebus.Asanoption,thestationaddresses
canalsobeassignedviathebus.
ThephysicalsystemsettingsaremadeusingtheparametersetoftheMaster.InadditiontothebusaddressoftheMaster,
thissetincludes,forexample,thebaudrate,thetime‐outdelaysandthenumberofrepetitionsofthetransmission.Along
withtheMasterparameterset,aSlavedatasetmustbesavedforeachSlavetobeactivated.Adatasetcontainsthe
parameterassignmentandconfigurationdataoftheSlaveandtheaddressindicatorforthelogicalstorageoftheI/Odata.If
theparametersetsarepresent,theneitherattherequestoftheuserorautomaticallytheMastersystembeginstostartthe
Slavesup,oneaftertheother.Thefirstso‐calleddiagnosticcyclesareabletoshow,whichslaveispresentonthebus.Only
thoseSlaves,whichsentacorrectfeedbackduringthediagnosticcycle,willsubsequentlybeparameterizedintheparameter
cycleswiththecorrespondingdatastoredintheMaster.Ifthishasbeencorrectlycarriedout,thenconfigurationcycles
follow,duringwhichacomparisonismadebetweentherequiredconfigurationdatastoredintheMasterandtheactual
configurationdataoftheSlave.Afterthelastdiagnosticcycle,eachSlaveforwhichnoerrorwasdetectedduringthe
comparisonisreadyforoperation.EachoftheseSlavesisthenintegratedautomaticallybytheMasterintheoperatingdata
transfer.
Fordiagnosticpurposes,theMasterprovidesadiagnosticbufferforeachSlave,whichcanbereadbytheuserforother
purposes.Tosimplifythediagnostics,ageneraldiagnosticfieldiskeptsimultaneously,whichshowsbitwisewhetheraSlave
hasdiagnosticdatareadyornot.

EN50170leavesituptotheusertodecide,whethertouseshieldedorunshieldedcable.Unshieldedcableisallowedin
interference‐freeenvironments.However,thefollowingpointsargueforsystematicuseofshieldedcable:
a) Anareafreefrominterferenceexistsatbestinsideshieldedcabinets.Butassoonasthiscontainsotherelectronic
devicessuchasrelaysandcontactors,thenthisisnolongerguaranteed.
b) Theuseofunshieldedcablesrequiresadditionalprotectivemeasuresagainstovervoltageatthebussignalinputs.
Thisiswhywerecommendonprincipletheuseofshieldedcablesforthebuslines.Thisrecommendationextendsalsotothe
possibleuseofpower‐supplycablescomingfromexternalpowersourcestothePROFIBUSdevices,e.g.forrepeaters.
Double‐shieldedcablesareparticularlysuitableforenvironmentswithstrongEMCinterference.Inthiscase,inorderto
ensureoptimalprotection,thewholesurfaceoftheexternalshielding(braidedshield)andtheinnershielding(foilshield)
mustbeconnectedatbothcableendstotheprotectiveearthbymeansofanearthclip.
Shieldingrules
Whenusingashieldedbuscable,itisrecommendedtoconnecttheshieldatbothendstotheprotectiveearthusinglow‐
inductionconnections.Thisensuresthehighestpossibleelectromagneticcompatibility(EMC).Oneexceptionconcerns
separatedpotentials(e.g.inrefineries):generally,intheseplants,earthingispermittedatoneendonly.
Theconnectionbetweenthecableshieldingandtheprotectiveearthisbestdoneusingthemetallicdevicehousingandthe
screwterminaloftheplugconnector.Hereitshouldbenotedthatdischargeviathepindoesnotrepresentanoptimal
solution.ToachievethebestEMC,itisbettertoexposethecableshieldingatasuitablelocationandtoconnectittothe
protectiveearth(e.g.themetalliccabinetframe)usingalow‐inductioncablelinkthatshouldbekeptasshortaspossible.
Thiscanbedoneforexamplewithashieldingclipbeforethebusplug.

5 Characteristics of the Multiturn Encoder on the Profibus Characteristics of the Multiturn Encoder on the Profibus
PNO‐Ident‐Number
TheSendixAbsoluteSingleturn/MultiturnEncoderhasthePNO‐Ident‐Number5868(Hex).Thisnumberisregisteredatthe
PNO(ProfibusUserOrganization)asanuniqueidentification.TheaccordingGSD‐Filesarenamedasfollows:
•MultiturnSeries5868,5888 KUEB5868.GSD
•SingleturnSeries5858,5878 KUEB5868ST.GSD
StartphaseoftheencoderonthePROFIBUS
Whentheencoderstartsupitisinthe‘Baud‐Search’state.Oncethebaudratehasbeenrecognized,itswitchestothe
WAIT_PRMstateandwaitsfortheparameterdatafromtheDP‐Master.Theparameterisationoccursautomaticallywhenthe
DP‐Masterstartsup.Thefollowingparametersaretransmittedtotheencoder:countdirectionandthemeasuringlengthin
steps(formoredetails,seetheEncoderProfilefromthePNO).Whenthecorrectparameterdatahavebeensuccessfully
transferred,theencoderswitchestotheWAIT_CFGstate.ThePROFIBUSMasterthensendsaconfigurationbyteto
determinethenumberofinputs/outputs.Iftheconfigurationbyteiscorrect,theencoderswitchestothestate
DATA_EXCHANGE.
ConfigurationandParameterisation
Theparameterisation,i.e.thetransferoftheparametersforcountdirection,encoderresolutionetc.,normallyoccurswithin
theconfigurationprogrammeforthePROFIBUSMasterused.Todothis,thetypefileorGSD(devicefile)shouldbecopiedto
therespectivedirectoryfortypeorGSDfiles.WithsomeprogrammessuchasCOMPROFIBUSorSTEP7Manager,anupdate
oftheinternaldevicelist(hardwarecatalogue)mustbecarriedoutwithinthesoftware.Formoreinformationabout
integratingfielddevices,pleaserefertothedocumentationforthesoftwareyouareusing.
ThetwostepsdescribedbelowarenormallynecessaryforintegratingandparameterisingtheencoderinaMastersystem.
Configuration
Forconfigurationpurposes,i.e.toinputthelengthandtypeoftheI/OonthePROFIBUS,theconfigurationprogramme
normallyprovidesaninputmask(screen),inwhich–independentlyofthedesiredconfiguration–theidentifierhasnormally
alreadybeensetasadefault,sothatonlytheI/Oaddressesremaintobeentered.Dependingontherequiredconfiguration
thatisdesired,theencoderallocatesavaryingnumberofinputandoutputwordsonthePROFIBUS.
Thefollowingparametersdescribedarealsodependentontherequiredconfiguration.TheGSDdevicefile(e.g.
KUEB5868.GSD)containsfiverequiredconfigurationsforPNOClass1and2,eachwith16‐and32Bitresolution.
