1745-E151控制器1745-E151控制器1745-E151控制器两个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。TEXASINSTRUMENTSPLC505-6108ANSPP5056108ATITEXASINSTRUMENTS530-1104CONTROLLERPLCMODULETEXASINSTRUMENTSPLC510-3103USPP5103103NACHIUM853-AUSPPUM853ATEXASINSTRUMENTS520C-1102SERIES500CONTROLLERREV2.6520C1102ASEABROWNBOVERIMEM86-192KNSPPMEM86192KSIEMENS6RA2203-8DK27-1NSFP6RA22038DK271TexasInstruments5TI-3000Perceptron495-0294ReplacementCircuitBoardTEXASINSTRUMENTSPLC500-5184USPP5005184TexasInstruments(Siemens)TI-435PLCw/RackModulesPanasonicACServoDriverDriverMUDS023A1MNewinBoxFreeShipSIEMENS6SE6-400-4BD24-0FA0NSFP6SE64004BD240FA0TEXASINSTRUMENTSPLC140-1114NSFP1401114TEXASINSTRUMENTSPLC505-4317NSPP5054317PanasonicACServoDriverMSDZ043A1AFreeShipTEXASINSTRUMENTSPLC315-DDUSPP315DDASEABROWNBOVERIACS501-010-4-00P2USPPACS501010400P2TexasInstrumentsRTU-T056A&520-058TEXASINSTRUMENTSPLC505-CP2572NSPP505CP2572MITSUBISHIMTA250-VUSPPMTA250VBRISTOLBABCOCKRTU-3305USPPRTU3305ASEABROWNBOVERIMD3B1SPFRGUSPPMD3B1SPFRGSIEMENSTEXASINSTRUMENTS555-1103``XLNT``FASTSHIPPINGTEXASINSTRUMENTS500-5001INPUTMODULELOT5005001TEXASINSTRUMENTSPLC505-3508NSFP5053508ASEABROWNBOVERIYTE-102CUSPPYTE102CDAWNINDUSTRIES11-1005686-03USPP11100568603TEXASINSTRUMENTSPLCMP6000USPPMP6000ASEABROWNBOVERI57088630USPP57088630SQUARED9070-T3000D3USPP9070T3000D3PanasonicACServoMotorM***A021A1FFreeShipPanasonicACServoDriveDV451S075#37772TEXASINSTRUMENTSPLC5TI-1034-1USPP5TI10341ALLENBRADLEY1784-KTK1NSPP1784KTK1PANASONICACSERVODRIVERDV85005LD5BSFreeShipOnePanasonicServoDriverMBDDT2210FreeShipSTARAutomationRobotPanasonicACServoMotorM***A152P1GFreeShipPanasonicM***D012S1AACServoMotorNEWFreeShipM***A042A1GPanasonicACServoMotorNewinBoxFreeShipFANUCA06B-6077-H106USPPA06B6077H106PanasonicACServoMotorM***042AAAXFreeShipTexasInstruments5TI-3201MODICONALU151-1USPPALU1511TEXASINSTRUMENTSPLC55IR8304070634USPP55IR8304070634CONTROLTECHNIQUES960154-01USPP96015401(AG01)PANASONICMSDA083D1AACSERVOMOTORDRIVERWORKINGALLENBRADLEY512-CJB-6P-24RNSPP512CJB6P24RTexasInstruments500-5005EXLARGSX30-1402-MCM-AB5-368-RBNSPPGSX301402MCMAB53TEXASINSTRUMENTSPLC500-5013NSPP5005013TEXASINSTRUMENTSPLC505-7016USPP5057016OnePanasonicMSDA043D1AACServoDriverFreeShipPANASONICM***011A34ACSERVOMOTORw/ReducerGearASEABROWNBOVERI57510001-AA/5USPP57510001AA5SIEMENS6SE3-216-8CB40NSFP6SE32168CB40TEXASINSTRUMENTS500-50235005023GENERALELECTRICCR209U000AEAUSPPCR209U000AEAAYDINCONTROLS460-5164-ABUSPP4605164ABtexasinstruments500-5035PROGRAMMABLEBASICMODULETEXASINSTRUMENTSPLC505-4708NSFP5054708ASEABROWNBOVERIDSFS-11USPPDSFS11)
