A process control or automation system is used to automatically control a process such as chemical, oil refineries, paper and pulp factories. The DCS (distributed control system), which is traditionally proprietary. Process automation simplifies this with the help of sensors at thousands of spots around the plant that collect data on temperatures, pressures, flows and so on. The information is stored and analyzed on a computer and the entire plant and each piece of production equipment can be monitored on a large screen using SCADA (supervisory control and data acquisition) in a control room. IEL (GCAPL) fulfills such needs with the required safety standard and process information.
