Hello fanana Although I am no expert of SICAM 1703. However will try to answer some of your questions : a) You would need the two Nos. SM-2551 Serial Modules for IEC-103 Serial Comminication with SIPROTEC Relays. b) You would also need the 2 Nos. SM-0829 RS232 to RS485 Convertors as the SM2551 provided you with RS232 ports and you need to use RS232 to RS485 convertors in order to communicate with SIPROREC Relays on IEC-103 Protocol using RS485 network. c) You of course cannot implement Modbus TCP/IP with this hardware unless you add SM2556 or SM2557 ( Ethernet Module ). We normally use SM2556 + SM0551Plug Module for EThernet + Serial communication. Hope this helps Cheers Navnag |

dear navnag thank you for your support i have found in the manul of SM2551 that it supports RS232 only but i am wondering of the probabilitty attched PDF file ,i see that RS485 used in the siprotec devices and also SICAM 1703 suport the RS485. but any way we have CM0829 so it is OK,but now ,i am still looking for a soluation for our configuration ,unfortunatelly i didin't order this equipment but i am a commissioning engineer and i am looking for a soluation so advice my all experts here AttachmentIEC_60870_5_103_Intop_ACP_ENG.pdf (292 Downloads) |

Dear fanana Since you have only Serial Ports in your TM, you can either provide the data to DCS on Modbus RTU Protocol. This is probably your best Bet. You caould use Mudbus RTU to TCP/IP convertors available , but since this calls for ordering additional hardware anyway, it may be better to order Ethernet boards for the TM itself. Probably you can start with commissioning the IEC-103 link and implement the link withDCS using Modbus RTU and later switch to Modbus TCP/IP when you have suitable hardware avalable Good Luck Cheers Navnag |

please note that only sm2556 can support modbus tcp/ip. |
