I stuck into a problem for searching an appropriate controller to communicate between RS485 and RJ 45. I want to communicate my data over a ethernet connection instead of a modbus but my present circuit has an installation of MODBUS communication. So how can I make communication between RS485 and Ethernet ???

 

Is this a hobbyist project and you're looking for an IC to design a circuit around, or a professional automation project and you're looking for a proven Modbus RTU/TCP protocol bridge?

Its an professional project for me.

In that case I recommend Moxa products, specifically this one:

I want to design my own Board. can you please suggest me a appropriate IC?

 

RJ45 is a connector. RJ45 connectors are commonly used for RS485 signals.

 

I think that could be done with Arduino, so that could be a place to start. Prototype with an Arduino and ethernet and RS485 modules, then duplicate that on your own board.
