Step2 : Programming and make the data transmission
We need use the function block “Modbus read and write” function block is the master CPU. The TCP server
or the TCP client CPU can work as master or slave. It totally decide by yourself. Following chapters we will
use examples to explain how to create the communication between 2 Ethernet CPUs.

Clients)
