SIMOVERT MASTERDRIVES Vector ControlEngineering InformationCommunicationCompact PLUS/compact andchassis units · cabinet units6USS protocolThe user data which can betransmitted with the USSprotocol have the structureshown in Fig. 6/61.The PKW area allows readingand writing of parametervalues and the reading ofparameter descriptions andtexts. This mechanism ismainly used for exchangingdata for operator control andvisualization as well asstart-up and diagnosis.The PZD area contains thesignals necessary for processcontrol – such as controlwords and setpoints – fromthe automation system tothe drive, and status wordsand actual values from thedrive to the automationsystem.For MASTERDRIVES VectorControl units, USS interfacesare available on the basic CUVC board(SCom1, SCom2) the T100 technology board the SCB2 interface board.Bus topologyThe USS bus is to be establishedas a line without spurlines.Bus cableThe SINEC L2 bus cable(Order No. 6XV1830-0AH10)can be used as the buscable. The maximum cablelength is 1200 m.Installing the bus cableThe USS bus cable is usuallyconnected with screw orplug-in terminals. TheSCom1 on the basic boardis accessible via a 9-poleSUB-D socket. The pin orterminal assignment of theSCom1 is given in Section 2and that of the SCom2 in thesection “System components”.The assignment of the interfaceon the supplementaryboards can be found in therespective operating instructions.1) For the ordering data of the additionalitems, see Catalogs ST 50and ST 70.Fig. 6/61Telegram structure with the USS protocolUSS-Master Additional hardware/software 1 )SIMATIC S5Protocol frame User data Protocol framePKEPKW areaINDLength: 0, 3, 4 words or variablePKW: Parameter ID valuePZD: Process dataPKE: Parameter IDAG95/AG100U with CP521 Sicommunication processorAG115 to AG155U with CP524communication processorPWEPZD 1PZD areaLength: 0 to 16 wordsIND: IndexPWE: Parameter valuePZD 16RS232/RS485 interface converterDVA_S5 option package for SIMATIC S5 (see page 2/12 and 3/92)RS485 interface module for CP524373 memory module for CP524COM 525 parameterization software for CP524S5R00T special driver for CP524 (6ES5897-2MB11)DVA_S5 option package for SIMATIC S5 (see page 2/12 and 3/92)SIMATIC S7 S7-200 (CPU 214, 215 or 216) STEP 7-MICRO/DOS or STEP 7-MICRO/WIN configuration tool forS7-200S7-300 with CP340-1C Configuration package for CP340, point-to-point couplingDrive ES SIMATIC (STEP 7 V 5.0) option software(see pages 2/13 to 2/15, 3/91 and 3/92)S7-400 with CP441 X27 RS422/RS485 interface moduleConfiguration package for CP441, point-to-point couplingDrive ES SIMATIC (STEP 7 V 5.0) option software(see pages 2/13 to 2/15, 3/91 and 3/92)SIMATIC TI FIM505 field interface moduleSIMADYN D CS7 adaption board with SS4 interface modulePCRS485 interface card or RS232/RS485 converter, USS driverBus terminationThe bus cable is to be terminatedat both ends (first andlast node). In the case ofMASTERDRIVES VectorControl units, it is terminatedwith the S1 switches(SCom1, X300) or S2(SCom2, X101) on the baseelectronics board.Possible USS masters are a user-friendly operatorcontrol panel, OP1S(local operator control) a Drive ES or a DriveMonitorPC (central parameterizationand diagnosis) or an automation system(see table).Possible USS automationmasters and the necessaryhardware/software additionsare shown in the table.Configuring of USScommunicationConfiguration of USS communicationin an automationsystem consists of the followingsteps: parameterization of theUSS master creation of the communicationprogram in the master parameterization of thedrives.Parameterization of the masterand the communicationprogram is system-specific.Parameterization of thedrives consists of two steps(example of SCom1/SCom2): parameterization of the interface(parameters P700,P701, P702, P703, P704) parameterization of the processdata interconnectionand parameterizing enable(control words P554 toP591, setpoints P443,P433, etc., status wordsand actual values P707,P708, parameter accessP053).6/56Siemens DA 65.10 · 2003/2004
Compact PLUS/compact andchassis units · cabinet unitsSIMOVERT MASTERDRIVES Vector ControlEngineering InformationCommunicationPROFIBUS DPIf the PROFIBUS DP is used,the CBP or CBP2 communicationboard is necessary forinterfacing drives to higherlevelautomation systems.With extended functionality,CBP2 is fully compatiblewith CBP and has replaced itas standard. In the following,therefore, “CBP”signifiesboth boards; individual specialfeatures of CBP2 are indicated.Functionality of the CBP Cyclical user data exchangewith the master accordingto the “PROFIBUS Profilefor PROFIDRIVE Variable-Speed Drives ”(Order No.3.071, PROFIBUS Nutzerorganisatione.V., Karlsruhe). Acyclical communicationchannel for exchangingparameter values up to alength of 118 words with aSIMATIC S7 CPU. Acyclical communicationchannel for connectingthe Drive ES Basic start-up,parameterization anddiagnostics tools. Support of the PROFIBUScontrol commands, SYNCand FREEZE, for synchronizeddata transfer from themaster to several slavesand vice versa.Extended functionalityof CBP2to PROFIBUS profile, drivesystems V3 PROFIDRIVE Flexible configuration ofcyclic messages at up to16 process data words Direct communication fordirect exchange of data betweenslaves Acyclic communicationchannel for direct access ofa SIMATIC OP to a drive.System connectorFixing screwFig. 6/62CBP communication boardPossible user data structures with CBP and CBP2DA65-5102Fixing screwLED (green)LED (yellow)LED (red)9-pole Sub D terminalX448PPO-Type PKW area PZD area FunctionalityPKW IND PWE PZD1 PZD16 CBP CBP2PPO1 fixed length: 4 words fixed length: 2 words ✔ ✔PPO2 fixed length: 4 words fixed length: 6 words ✔ ✔PPO3 fixed length: 0 words fixed length: 2 words ✔ ✔PPO4 fixed length: 0 words fixed length: 6 words ✔ ✔PPO5 fixed length: 4 words fixed length: 10 words ✔ ✔none 0 or 4 words flexible configurable from1 to 16 words✔PKW: Parameter ID value IND: IndexPZD: Process dataPWE: Parameter valuePKE: Parameter IDCyclic exchange ofuser dataIn the PROFIBUS profile onwhich the CBP functionalityis based, the structure of theuser data, amongst otheritems, with which a DP mastercan access the drives isdefined. There are five permanentlydefined PPO (parameterprocess-data objects);these are subdividedinto a PKW area (parameteridentifier value area, up to4 words) and the PZD area(process data area, up to10 words).The PKW area enables readingand writing of parametervalues and the reading ofparameter descriptions. Thismechanism is used to visualizeor change any of theslaves’parameters.The PZD area contains thedata – such as control wordsand setpoints needed forprocess control – from theautomation system to thedrive or status words and actualvalues from the drive tothe automation system.When a CBP2 is used, localuser data structures with upto 16 process data words cannow also be utilized in additionto the five PPO types.Technical data of the CBP RS485 interface acc. toEN 50 170, short-circuitproof and floating Baud rates from 9.6 Kbit/sto 12 Mbit/s.Mounting of the CBPIn MASTERDRIVES VectorControl, slots A, C, Eand G in the electronicsbox are available (see alsopage 6/54). For slots Gand E, the local bus adapter(6SE7090–0XX84–4HA0)and the adapter board(6SE7090–0XX84–0KA0)are necessary.6Siemens DA 65.10 · 2003/20046/57
