In this project Iam going to use MODBUS data frame over ethernet. Im going to use UDP protocol to send data.

Modbus commands will travel as data packets over the ethernet network as raw packets.

Im using packet sender software to test this experiment.

Supplies

Arduino Uno

Ethernet shield

LED and 220 ohm resistor

Bread board

some wires

USB Arduino programming cable.

Ethernet LAN cable

In this experiment i am going to send the raw packets of data over ethernet using the UDP protocol. My data packet consists of Modbus data that will be analysed by Arduino Uno and intended action is taken.
