Modbus RTU and Modbus ASCII talks the same protocol. The only difference is that the bytes being transmitted over the wire are presented as binary with RTU and as readable ASCII with Modbus RTU.

This paper explains how to set up the communication between PLC and Arduino based on Modbus Protocol. PLC is a master and Arduino is a slave. A Fx2N-48MR, a Fx2N-485BD, an Arduino main board and an ...
