In this project im going to control devices using Modbus over ethernet. Im going to use TELNET protocol over ethernet. The Modbus data packet will be transported over ethernet using TELNET protocol.

Supplies

Arduino Uno

Ethernet Shield

USB Arduino cable.

LED and 220 ohm resistor.

Ethernet cable.

Step 1:

In this video Im going to transmit Modbus data over ethernet network using Telnet protocol. Arduino Uno will be used as a server.

Modbus frame will be processed by Arduino Uno and required action will be taken.

This is a tested project.

Modbus data is passed over telnet protocol.
