Boiler Application Using Wireless Bridge between PLC and SCADA

In this paper, study of wireless SCADA system which is powerful setup for monitoring and controlling the various applications from remotely placed is presented. Wireless SCADA is required in those applications when wire line communications to the remote site is prohibitively expensive or it is too time consuming to construct. In certain industries like Oil& Gas or Water& Wastewater, wireless SCADA is often the appropriate solution due to the remoteness of the sites. The project discusses the concept of monitoring, recording and controlling of a small part of the boiler process. This is done by using PLC and SCADA. The PLC and SCADA are connected with a wireless medium, that is, the Bluetooth module. The boiler process consists of parameters such as, temperature, level and pressure. The effect of these parameters, when they exceed their limit is shown in SCADA and its resulting control is done on the real time operation of the boiler. This is done with a help of Bluetooth module, which will be wirelessly used to connect the PLC and the SCADA. Wireless based solutions have universally accepted, familiar and user friendly system. Real-time logging would allow warnings to be flagged to the relevant personnel (e. g. Indicate warning signs in the SCADA display for the personnel to operate and rectify the problem/ issue) and allow corrective action to be taken before the quality and value of the catch is degraded. The SCADA can be connected by using a Wi-Fi, but in our case of project to control the boiler we use Bluetooth as the medium, as we are going to operate the process in a smaller range of the Bluetooth module. This is done with a help of Bluetooth module, which will be wirelessly used to connect the PLC and the SCADA
