Abstract

Control and Instrumentation in any process industry can be compared to the nervous system in the human being. In industries and process plants, instrumentation makes use of various measuring components designed to suit the process. Generally in power plants to discharge effluent water, a separate arrangement known as EDP/H (effluent disposal pump house) is installed and the communication from EDP pump house to control room for commands and feedbacks are hardwired, when the input is given to the PLC (programmable logic controllers) like pump on/off then only the pumps are operated. Sometimes, there will be possibility of breakdown of the wire, to recover these breakings and to establish the proper communication between the wires again, junction boxes are used. It is a very lengthy, difficult and expensive process to lay fresh cables and whenever these cables are immersed in water due to rains and drains overflow, then the control system is getting disturbed because of short-circuit. To overcome this problem, wireless communication is established between the EDP/H and control room through PLC to PLC wireless communication. The current paper deals with the “wireless communication for control of effluent disposal pumps using plc”.
