Design of industrial plc based on zigbee protocol

Abstract

According to the view of Intelligent Industry, this paper proposes a real-time system which can monitor the Programmable Logical Controller (PLC) working parameters like the relay states and response to abnormal ones. This system includes the ARM micro-processor, wireless RF transceiver modules and PLC. The wireless RF transceiver module owns a micro-controller to collect PLC parameters. Then the obtained parameters will be sent to ARM microprocessor by a RF transceiver using ZigBee protocol. The microprocessor stores the collected parameters and analyses received data, if parameters do not accord with a standard one, the microprocessor will inform the user by sounding the beeper. Even the microprocessor can directly stop PLC, if necessary. © 2012 Springer-Verlag Berlin Heidelberg.
