IR Remote Control - Programmable Logic Controller (PLC) - Arduino

PLC Application about how to use the IR Universal Remote Control for Programmable Logic Controller (PLC).
This application uses Arduino and IR Remote Control Module.
Communication between Programmable Logic Controller (PLC) and Arduino Using Modbus RTU.
IR Remote Control in this application used for Input Password on Machine by Infra Red Communication.

Input Password on PLC using IR Remote Control

1. IR Remote Control Module
2. Arduino UNO
3. TTL to RS232 Male Module
4. RS232 PLC Cable
5. Siemens PLC, or Others PLC with Modbus Support
