Abstract

Sistem kontrol Distributed Control System (DCS) sangat umum digunakan pada plant yang berukuran besar dan kompleks. Pada proses yang menggunakan sistem kontrol ini, fungsi kontrol proses didistribusikan pada beberapa controller individual yang menangani loop yang berbeda-beda yaitu pada Local Control Unit (LCU). Pada penelitian sebelumnya sudah dikembangkan sistem kontrol Distributed Control System (DCS) pada miniplant workshop instrumentasi mengenai dua Local Control Unit (LCU) yaitu level dan flow, namun pada Local Control Unit (LCU) temperature dan pressure belum dibuat. Perancangan disini dibuat sebagai suatu sistem pengendalian dimana variabel kontrol temperature dan pressure ini masing-masing ditangani oleh local control unit yang dapat dikendalikan dari workstation server maupun client dan keseluruhan sistem terintegrasi dalam sebuah system Distributed Control System (DCS) secara online dan real time. Pada perancangan Local Control Unit (LCU) ini juga meliputi perancangan sensor tekanan dengan menggunakan pressure gauge yang telah dimodifikasi dengan nilai sensitivitas sebesar 4.7 mV/cm dan menggunakan mode pengendalian ON-OFF dengan tingkat linearitas terbaik pada tekanan 3-8 Psi

Distributed Control System (DCS) control systems are very commonly used in large and complex plants. In processes that use this control system, the process control function is distributed across several individual controllers that handle different loops, namely the Local Control Unit (LCU). In previous research, a Distributed Control System (DCS) control system had been developed in the miniplant instrumentation workshop regarding two Local Control Units (LCU), namely level and flow, but the Local Control Unit (LCU) temperature and pressure had not been created. The design here is made as a control system where the temperature and pressure control variables are each handled by a local control unit which can be controlled from the server or client workstation and the entire system is integrated in a Distributed Control System (DCS) online and in real time. The design of the Local Control Unit (LCU) also includes the design of a pressure sensor using a modified pressure gauge with a sensitivity value of 4.7 mV/cm and using ON-OFF control mode with the best level of linearity at a pressure of 3-8 Psi.
