Hi arnie, S7 1200 hasn't library for LonWorks protocol, but if you need, you can implement the protocol and use a CM RS 485 module. The protocols supported are: Through the ethernet port: TCP/IP, ISO on TCP andin the near future,PROFINET and UDP. Modbus TCP for PAC3200 (library). ThroughtheCMmodules: RS485Modbus and USS (library) RS232PtP. In the near future PROFIBUS CM module and GSM CM module. Take a look at this link: https://www.automation.siemens.com/mcms/programmable-logic-controller/en/simatic-s7-controller/s7-1200/communication/Pages/Default.aspx |

Thanks Mr Paiva for your reply, I find out that there is a module DP/LON link in the siemens building technology so i hope that i can make a connection with the new Profibus module for s7-1200 arnie AttachmentDP_Lon_Link_Rev.May2003.pdf (383 Downloads) |

The phisical level of Lonwork protocol (one in ISO/OSI model) isn't RS485, but it is dedicated. This means no possible to use standard board of S71200 to develop comunication. Easiest way is Modbus master library on S71200 and a gateway LON-MODBUS outside. One of the possible gatewayLON-MODBUS is protonode ( http://www.marcomweb.it/ProtoCessor/ProtoNode.aspx ) But other LON-MODBUS gateway are available on the market. |
