I want to read some registers from a frequency inverter using a XMC4700 Relax Kit and the Arduino Modbus library. Unfortunately there are some warnings, notes and an ...

Contains examples of Modbus (RS485) communication with Arduino. The Arduino RS485 Module is used for RS485 communication. In the examples, Arduino Mega is used as the Master, and Arduino Uno is used ...

Abstract: 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 ...
