In this paper, the authors monitor and control the PLC based system using wireless technology. In this paper, they are going to use a ZIGBEE and SCADA technology to get wireless automation system. Pair of ZIGBEE is used here, among that one is connected with the PLC in the industry side and another one is connected with PC in the control room. Data from the PLC side will be transferred continuously to PC via ZIGBEE by sending a bit of the process that occurs in the industry and it will be displayed in the SCADA software and also users can control industry by transmitting a bit again using ZIGBEE from PC side to PLC located at the industry side.
