Optoelectronic isolated RS232/MPI,Siemens S7-300/400 PLC Programming adapter cable,with communication indicator,can replace Siemens 6ES7 972-0CA23-0XA0,automatically adjust the communication speed from 19.2Kbps to 115.2Kbps for the PC port,automatically adjust the communication speed from 19.2Kbps to 187.5Kbps for the MPI interface.Can connect PLC and the touch panel of third party factory to communicate.It doesn't support profibus function.PC/MPI+ adapter, or named PC adapter, could achieve the level conversion of RS232 to RS485 and the protocal conversion of RS232 to MPI(MultiPoint Interface).PC/MPI+ is the adapter of photoelectric isolation type towards industrial design. Between RS232 port and RS485 port exist the surge protection and anti-lightning protection circuit, adaptable to the full PLC series of Siemens S7-300/400 and those devices with MPI port, especially the industrial fields with greater interference and easily damaged communication port. All kinds of protection measures in the circuit give promission to the safe operation of the system.PC/MPI+ can make touch-screen communications with the third party under the link of S7-300/400PLC, such as eView, Wei-lun and kun-lun state.Characteristics and main technical parametres:★ Power: It is supplied by the 24VDC MPI port of PLC, power consumption of about 1w, with overcurrent protection and surge protection.★ Isolation Voltage: 1000VDC(Maximun to 3000 VDC, orders require statement.)★ RS232 port has anti-surge protection, RS485 port has anti-lightning protection and overcurrent protection with the consumption of 500w.★ RS232 port baud rate: 19.2Kbps---115.2Kbps, automatically adaptable to the standard baud rate.★ MPI port baud rate: 187.5Kbps---19.2Kbps, automatically adaptable.★ Supporting the connection of PLC to touch-screen communication with the third party.★ With a power indicater light, on-line and data transmission indicater light.★ Working temperature: -20～75'C★ Dimension: 103×50×26; After connecting the RS232 cables: 5.5m.RS232 adapter port and port-pin RS485 signal definations:Pin numberSignal nameInstructions Pin numberSignal nameInstructions1DCDNo use1NCNo use2RXDRS232 signal reception2M24VNegtive 24VDC power3TXDRS232 signal sending3BRS485 positive signal4DTRShort circuit with No.64RTSASData reception control5GNDRS232 signal to ground5GNDRS485 signal to ground6DSRShort cut with No.46NCNo use7RTSSending requsts7P24V24VDC positive power8CTSSending clear8ARS485 negtive signal9RINo use9RTS_PGData-send controlRS232-Block(DB9M) defination signals RS485-Block(DB9M) defination signalsIndicater lightOnQlitteringOutPowerNormalErrorError or failing to link to powerActiveOnlineTransmission of dataNot onlineTxErrorSend dataNo data transmission Instructions of the indicater lightSoftware settings of STEP7:Entering the main interface of STEP7 programming software(SIMATIC Manager),clicking on "Options"menu under the "Set PG/PC Interface…" option into the PG/PC interface settings.1. Double clicking on "PC Adapter(MPI)" into the RS232 interfaces and MPI set of parameters. The adapter does not support "PC Adapter(PROFIBUS)" option.2. Clicking on "Local Connection" option set RS232 interface parameters, choosing PC/MPI to connect on the port of COM correctly, and it will adapt to the chosen baud rate automatically, both 19200bps and 38400bps of RS232 communication.3. Clicking "MPI" to set port parameters of adapter MPI, acceptable at both 187.5Kbps and 19.2Kbps, and the adapter will adapt to its baud rate automatically. Others have already been set.4. On-line test accessing point: Using PC/MPI to connect to MPI port and RS232 port of the computer. And then click on the button in the red circle as follow, if appearing the data inside the red line, the test has passed. Then one could operate on it.The long-distance communication of PC/MPI+ adapter:1. To extend the distance of RS485 port: 2. To extend the distance of RS232 port:RS232 Cable:When you buy PC/MPI+,we will give you the free RS232 Cable.The quality is guaranteed.It's tested before shippment.Not made by Siemens,OEM product as the replacement.We produce PLC, HMI programming cables for almost all brands.Alternative, Substitutes only about 10% price as originalQuality and Reliable, Long Life, Sales Since Year 2002Siemens PLC Programming CableUSB-PPIOMRON PLC Programming CableUSB-CP1HT-VERTER PLC HMI CablePC-TP02USB-PPI+USB-CIF02USB-TP02PC-PPICQM1-CIF02TP-302MC6ES7901-3DB30-0XA0USB-XW2Z-200S-CVPC-TP036ES7901-3CB30-0XA0USB-XW2Z-200S-VHUSB-TP036ES7972-0CB20-0XA0USB-XW2Z-200S-VUSB-TP-302PC6GK1571-0BA00-0AA0USB-CN226TP-302MC6ES7972-0CA23-0XA0CS1W-CN226Proface HMI CableUSB- GPW-CB02PC-TTYCS1W-CN626GPW-CB026ES5 734-1BD20PC-CQM1HGPW-CB036ES7901-1BF00-0XA0USB-CQM1HUSB GPW-CB036ES7901-0BF00-0AA0XW2Z-200S-CVGP-FX6XV1440-2KH32XW2Z-200S-VHGP-FP0USB-OPXW2Z-200S-VGP-QLOGO!USB-CABLECS1W-CIF31GP-DVP6ED1057-1AA01-0BA0USB-CIF31GP-FBSLOGO!PC-CABLEXW2Z-200S-VGP-S7-2006ED1057-1AA00-0BA0XW2Z-200TGP-CPM1AUSB-TP-RS485XW2Z-500TGP2000-FX2NAllen-Bradley PLC Programming Cable1747-PICXW2Z-200P-VCA3-USBCB-011747-UICXW2Z-200PCA3-CBLFX-01USB-1747-CP3XW2Z-002TCA3-CBLQ-01USB-1761-CBL-PM02NB7-FXCA3-CBLFP-011761-CBL-PM02NB7-OMRONGP3000-DVP1747-CP3FANUC PLC Programming CableIC690ACC901GP300-S72002711-NC13IC690USB901GP3000-FBS1784-CP10KEYENCEUSB-KVCA3-CBLSYS-011784-CP11FUJI PLC CableUSB-CNV3Weintek HMI CableUSB-MT5002711-NC21USB-UG00C-TPC-MT5001761-CBL-HM02NN-CNV3MT500-FX1761-CBL-AP00Delta PLC Programming CableUSBACAB230MT500-S7-2001761-CBL-AM00DVPCAB215MT500-FBS1772-TCDOP-DVPMT500-FP01747-C13DOP-FX 5MMT500-CPM1A1786-CPDOP-FXMT500-AFPXCP3-PM02DOP-FXMT500-CP1H1756-CP3USB-DOPMT500-DVP2711-NC14DOP-USBMT500-S73002711-NC17PC-DOPMT6000-S73002711-NC11DOP-FP0MT8000-S73002711-CBL-HM00DOP-FBSUSB-MT6000iSchneider PLC Programming CableTSXPCX1031DOP-FP0MT6000-FXTSXPCX3030DOP-S7-200MT6000-S7200TSXPCU1030DOP-FPXMT6000-FBSTSX08PRGCABDVP-GPMT6000-DVPXBT-Z968USB-DVPMT6000-FP0XBTZ915DVPACAB2A30MT6000-AFPXXBTZG935DVPACAB630MT6000-QTSXCUSB485TP04-FXMT6000-CPM1AMITSUBISHI PLC Programming CableUSB-SC09DVPACAB530MT6000-NBUSB-SC09-FXDVPACAB515TK6070-FXSC09LG PLC Programming CablePC-LGTK6070-S7200SC-10PC-XGBTK6070-FBSSC-11USB-LGTK6070-DVPFX-USB-AWNAIS PLC Programming CableUSB-FP-XTK6070-FP0FX-232AWC-HUSB-AFC8513TK6070-AFPXUSB-QC30R2USB-AFC8503USB-MD204QC30R2USB-FP1PC-MD204USB-FX232-CAB-1AFC8503MD204-S7-200USB- AC30R2-9SSAFC8513MD204-FBSFX-20P-CAB0USB-GT32MD204-FXFX-20P-CABAFP5523MD204-DVPFX-20P-CADPAFC8523MD204-FP0FX-422CAB0AIGT8162TK6012-FXF2-232CAB-1AIGT8192MT6056-FXFX-232-CAB-1AIP81842Kinco HMI CableMT4000/5000-FXFX-50DU-CAB0AIGT8152MT4000/5000-FBSFX-40DU-CABUSB8550MT4000/5000-DVPFX9GT-CAB0USB8551MT4000/5000-S7200AC30R2-9SSAFP8550MT4000/5000-FP0AC30R4-25PAFP8551MT4000/5000-AFPXGT01-C30R4-8PAFP5523MT4000/5000-QGT01-C30R2-6PHitachi PLCEH-VCB02MT4000/5000-CPM1AGT01-C30R4-25PPC-HIDICMT4000/5000-XCUSB-GT01-C30R2-6PIDEC PLC ProgrammingPC-FC4AUSB-MT4000/5000GT01-C30R2-9SUSB-FC4AMT4000-S7300GT10-C30R4-8PVIGOR PLC Programming CableMWPC-200MCGS HMI CableUSB-TPCGT10-C50R4-8PMWPC25-200TPC-FXFX2N-485-BDVB-USB-200TPC-S7200FX2N-232-BDUSB-VIGORTPC-FBSFX2N-422-BDEmerson PLC ProgrammingSL-B2053RASL1TPC-DVPFX1N-485-BDUSB-SLB2053RASLTPC-FP0FX1N-232-BDKOYO9 PLC CableUSB-Koyo PLCTPC-AFPXFX1N-422-BDPC-SU PLCTPC-QFX3U-485BDHakko PLC CableV6-CPTPC-XCFX3U-422-BDUSB-V6-CPTPC-S7300FX3U-232BDHITECH HMI CableUSB-PWS6600TPC-CPM1AFX3U-CNV-BDPC-PWS6600FATEK PLC CableUSB-FBS-232P0GT09-C20USB-5PPWS6600-FXFBS-232P0-9FFX9GT-CAB0PC-HITECHUSB-FB-232P0-150SIMATIC HMI6XV1 440-2KH32PWS6600-S7200Provide programming software freeShippingDHL, UPS, Fedex, TNT, EMS, PostPaymentT/T, Western Union, Moneygram, PaypalMinimum Order Quantity1 pcsTechnical SupportfreeProgramming Softwarefree
