Hello SOble; Based on my souvenirs and the following documents, it seems that Modbus TCP is not an option for communications with the 7UM62. Modbus TCP/IP 7UM62 DIGSI 4Unless the communication options for the 7UM62 have evolved to include Modbus/TCP in DIGSI 5, the attachment below shows the available connection interface optionss; Modbus/TCP is not available.. If that is the case, either use a CPU with an additional RS-485 communication module that supports Modbus RTU or use a Modbus/TCP to Modbus serial converter with your Modbus/TCP program. (Edit: I see from other posts that you work with n ET 200S CPU; in that case the Modbus RTU additional module you should use is a 1SI module). Hope this helps, Daniel Chartier |

You mean, with internal TCP port is not possible, but I can order 7UM62 which includes MODBUS TCP/IP like attached pic shows |

Hello SOble; Your manual seems to be of a newer generation than mine, and it does point to a communication interface to Modbus/TCP. It would seem that you need purchase a specialized communication interface if you want to implement Modbus/TCP on your 7UM62. However, since I have no direct experience with this module, please follow the suggestion from the manual page you have just posted: "If you are in any doubt about the module type used in your communication application, consult your Siemens sales partner." Hope this helps, Daniel Chartier Edit: with a little search and a bit of luck, I located this document from the Siemens Digital Grid pages (from the Energy division that markets the 7UM62 relays; look in the Downloads/Ordering Information section): Which Protocols in which Relays The attached screenshot indicates that the 7UM62 cannot be configured with a Modbus TCP communication module. Sorry, Please confirm through the nearest Siemens office. D.C. |
