1771-CX5模块;1771-CX5模块;1771-CX5模块两个S7-300plc之间的数据交换通信可以有很多方式，根据具体的PLC型号不同，其相应的通信接口也不同，主要有：MPI、PROFIBUSDP和以太网通信。S7通信：通过S7连接的配置实现S7站间和PC站间的数据交换。S7连接的属性：该连接可用于所有S7/M7设备。可用于所有子网(MPI，PROFIBUS，工业以太网)。SIMATICS7/M7-300/400站之间数据的可靠传输(使用“BSEND/BRCV”或“PUT/GET”SFB)。高速，不可靠数据传输取决于对方与时间相关的操作(使用“USEND/URECV”SFB)。在ISO参考过程的第7层上确认对方的数据传输。MPI是西门子开发的用于PLC之间的保密协议，当通信速率要求不高、通信数据不大时可以采用的一种简单经济的通信方式，两个S7-300之间的MPI通信可以采用无组态连接的MPI通信，通过调用SFC67和SFC68通过简单编程来实现无组态的MPI通信，它既可以是双边通信，也可以采用单边通信方式;也可以采用全局数据通信的方式，无需编写程序，在硬件组态时组态所以MPI的PLC站之间的发送区和接收区即可。MPI通信硬件连接仅需1根PROFIBUS网络电缆(含两个网络总线连接器);两个S7-300PLC之间的现场总线通信，根据PLC是否自带DP通信口(如CPU315-2DP自带DP接口)而不同，如果自带DP接口，只需将两台S7-300PLC的DP通信口用PROFIBUS通信电缆连接即可，如果S7-300PLC没有自带DP通信口(如CPU315)，必须配置DP接口模块(如CP342-5)来实现PROFIBUS现场总线通信。而两个S7-300PLC之间的以太网通信有很多种方式，如ISOTransport、ISO-on-TCP、UDP(用户数据协议)、TCP/IP、S7通信，以CPU315-2DP为例，每个PLC需要组态CP343-1以太网模块，通过交换机用带水晶接头的8芯双绞线连接来实现以太网通信，比较简单，也是未来发展方向。DP/DPCouper是把两个PROFIBUSDP网络1和2耦合在一起，在通信的双方有自己***的DP地址，并且通信双方的PROFIBUSDP通信速率可以不一样，通过输入/输出区直接交换通信数据。TEXASINSTRUMENTSPLC08-35546-000USPP0835546000PanasonicMSD083A2XXACSERVODRIVERTEXASINSTRUMENTSPLC5TI-1013USPP5TI1013TEXASINSTRUMENTSPLC305-04BUSPP30504BSIEMENS6SN1118-0DA11-​0AA0NSPP6SN11180DA110A​A0PanasonicMFA075LD5NSJACServoMotor750WCUTLERHAMMERMES3800LSINSFPMES3800LSIOMRONCV500-MC221USPPCV500MC221PANASONICACSERVODRIVERMSDA3A3A1AASEABROWNBOVERISR4313150R23C2​EC1ABNSPPSR4313150R23C2​ECDECBA11-SEUSPPBA11SE500-5056TexasInstrumentsSiemensTI32ptoutputmodule5005056N300ASEABROWNBOVERI3HAB8797-1/2BUSPP3HAB879712BSECOQ7022-1USPPQ70221PERCEPTRON495-0092USPP4950092Perceptron495-0092PCBoardVMEgrapherVGAGraphicsASEABROWNBOVERI57160001-TPUSPP57160001TPGENERALELECTRIC193W-279AAG03USPP193W279AAG03TITEXASINSTRUMENTS(5TI-2001)PLCPROGRAMMERNICE!TELEMECANIQUETPMXP57102USPPTPMXP57102PanasonicACServoMotor***152A1C1.5kWwithPlugsPanasonicMUDS5A5A1AACSERVODRIVEMUDS5A5A1A50W200TEXASINSTRUMENTSPLC505-4317NSFP5054317TEXASINSTRUMENTS500-2151-APOWERSUPPLY5002151ATEXASINSTRUMENTSPLC944910-4-ALUSPP9449104ALPanasonicACServoDriverMDDDT55401.5KWFreeShipPanasonicACServoMotorMQMA012A5FLotof2UsedWorkingALLENBRADLEY1336S-BRF50-AN​EN-HA2-L6USPP1336SBRF50ANEN​H2SIEMENSTIPLCEXPANSIONRACK8SLOT6ES5-701-3LA12NEWPanasonicACServoDriverMSD083A1XXVTEXASINSTRUMENTSPLCPWB-2461414-00​01USPPPWB24614140001TEXASINSTRUMENTSPLC305-DC-04BUSPP305DC04BPanasonic/NaisServoM***D042P1U+MBD​DT2210NIB!ASEABROWNBOVERIQK-140-2R6500USPPQK1402R6500TexasInstruments2497447PCBoardTEXASINSTRUMENTSPLC505-5190NSPP5055190SAJF//PANASONICMSD043A1XXVM***042A1ESCSERVODRIVERSCSERVOMOTORUSEDGENERALELECTRICIC2820A103EUSPPIC2820A103ETexasInstruments500-5031JSAFTRONICSCIMR-H11G2-E-1​0USPPCIMRH11G2E10OMRONF3SN-A0207P14USPPF3SNA0207P14TexasInstruments500-5053BasicModule#7334TexasInstrumentsRTU-84503DUALRS2BDASEABROWNBOVERIEH550G-PRL11USPPEH550GPRL11TexasInstrumentsRTU-T059-TTERMINATIONPANELASEABROWNBOVERIDSDX-110NSFPDSDX110NEWTEXASINSTRUMENTSMODEL500-5032ISOLATEDINPUTGENERALELECTRICCR193C110L0070​80UNSFPCR193C110L0070​80TEXASINSTRUMENTSPLCPM550-210USPPPM550210TEXASINSTRUMENTS500-5011OUTPUTMODULELOT5005011ASEABROWNBOVERIACH550-BD-180A​-4NSFPACH550BD180A4LEYBOLDSV25-109-03-51USPPSV251090351BANNERENGINEERINGMGE-4216ANSFPMGE4216APANASONICACSERVODRIVERMSDA3A3D1AFreeShipMITSUBISHIA3NMCA24RUSPPA3NMCA24RPanasonicACServoDriverMBDDT2210053FreeShipASEABROWNBOVERIYST45-28NSPPYST4528GENERALELECTRICDS3800DOAAUSPPDS3800DOAAPanasonicMQDB012AAD02208V100W1.0AACServoDrive0190-15328newTEXASINSTRUMENTSPLC945170-0001-MUSPP9451700001MALLENBRADLEY1326AB-B420H-2​1USPP1326ABB420H21ALLENBRADLEY284D-FHD6P0D-2​5-CR-3NSFP284DFHD6P0D25C​R3TISiemens500-50545005054RedundantTiwayPeerlinkPLCPERCEPTRON495-0102-01USPP495010201PanasonicACServoDriverMSDA043A1A#2FreeShipASEABROWNBOVERIACS401601132NSFPACS401601132TISiemensCTi500-50195005019WordOutputPLCTEXASINSTRUMENTSPLC505-6851BNSFP5056851BTexasInstruments14SlotRackBase500-5848#23931FISHERROSEMOUNTDC6554X1-DA1USPPDC6554X1DA1FORCECOMPUTERSSYS68K/RR-3USPPSYS68KRR3TEXASINSTRUMENTSPLC560-2123USPP5602123TexasInstruments500-2114RemoteBaseControllerASEABROWNBOVERI(ABB)DSDP140BBOSTONGEARFWA726-1800-B5​-GUSPPFWA7261800B5GASEABROWNBOVERI3AFE61004955NSFP3AFE61004955PERCEPTRON917-10089171008S0400-X0075-Y0​102-Z0215SURFACESENSORTRICAM560-2820TITexasInstrumentsPowerSupply5602820)
