Abstract: In chemical process industries pressure is one of the key process variable as pressure provides a critical condition for any process in an industry. Inaccurate pressure control will result in major safety issues, poor quality, and productivity problems. More over high pressure inside a sealed vessel can cause an explosion. Therefore, it is highly desirable to keep pressure in good control and maintained within its safety limits. This paper aims for online control and monitor of pressure variable by interfacing with DCS and the same is operated as remotely triggered unit. Many process industries will monitor and control many different manufacturing processes at the same time. Overall monitoring and controlling of all the process at the same time instance will lead to increase in process productivity and plant safety. Distributed control and centralized monitoring are the key-factors to ensure the plant safety. This paper aims to enhance the flexibility in controlling and monitoring of pressure process station by configuring and developing Field Control Station (FCS) & Human Interface Station (HIS) using DCS. The PID controller attempts to minimize the error by adjusting the controller output. The PID controller parameters are calculated by using Cohen and coon tuning algorithm. The field output of pressure process station is fetched and the parameter is been sent to the distributed control system (DCS) where the controlling and monitoring of the pressure variable in the pressure process station is performed by the DCS. Thus the optimized control of pressure process is been achieved.
