i want to use Connexium Twido Ethernet Interface Modul as ethernet-rs485 converter. And i think that the power suply for this module using the rj45 connector for modbus communication.

How is the cable diagram so i can use it as the ethernet-rs485 converter and i use external power supply for the module?

 

Do you mean the Twidoport???

This has an RJ45 connector for Modbus, and a second for Ethernet. The cable that connects the Twidoport to the Twido (Modbus rs485) also carries the supply. Try looking in the Twidosoft help files. Try looking on telemecanique.com for details of gateway being used!
