The sketch creates a Modbus actuator using the IS4310. The Arduino reads Modbus Holding Registers 1, 2, and 3 and maps their values to an RGB LED—creating a simple pixel controlled over Modbus RTU.

Arduino-based Modbus RTU to Modbus TCP/UDP gateway with web interface. Allows you to connect Modbus RTU slaves (such as sensors, energy meters, HVAC devices) to Modbus TCP/UDP masters (such as home ...

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 ...
