A multiple PLC wireless communication module using master-slave control concept

Mastey-Slave 개념을 이용한 PLC용 다대다 통신 모듈 개발

We developed a wireless communication system for multiple instrumentation system. The developed system has a function of remote instrumentation and PLC(Programmable Logic Controller) control. The system consists of CC(Control and Communication) protocol, wireless media access and physical media system. For multiple wireless communication, we propose a hub polling protocol based on master-slave control concept. To show the validity of the developed system, several experiments are illustrated.
