Integration of WirelessHART devices into mitsubishi PLC for plant monitoring

This paper presents a technique to integrate WirelessHART devices into Mitsubishi PLC for plant monitoring. The integration between WirelessHART devices and Mitsubishi PLC is based on OPC technologies. DASMTEthernet OPC and DASMBTCP OPC are used to communicate between WirelessHART devices, Mitsubishi PLC and SCADA software. Commercial WirelessHART devices and Mitsubishi PLC are used in experiment. The experimental testing with Pneumatic object moving plant shown the proposed system can monitor pressure and temperature of air compressor and stop the operation of Pneumatic object moving plant when the pressure and temperature of the air compressor are out of defined range. The experimental results illustrated here are useful people interested in the use of measuring multiple parameters for monitoring conditions of industrial plant controlled by Mitsubishi PLC including commercial PLC.
