INDUSTRIAL CONTROL SYSTEM APPLIED AND PROBLEMS: A REVIEW AND EXPERIENCES

Abstract

This paper aims to explain examples of industrial control system applications that are applied in the industrial world today and the problems that arise in the Industrial Control System (ICS). The methodology used in this paper is to review several journals, books, and work experiences (experiment). SCADA in the highest position, the DCS at level 2, then the PLC at the very bottom. And there are two problems encountered, namely in terms of hardware and software. In case of hardware problem SCADA, DCS and PLC hit by lightning, exposed to droplets of water seepage, electrical fuse problem, the temperature of the hot room, high humidity, mainboard problem (due to lifetime), power supply (due to lifetime and bad electric power supply). In terms of the software, its software is corrupt, so it should be in the re-install. In general, a CD contains software for one PC (personal computer) because there is one CD software there is activation code where when you enter the activation code must be connected to the internet network that is detected automatically. The effect that causes the most loss was a broken fuse. So, dividing the same load each digital output or part is good architecture. The SCADA system had to be more concerned for cybersecurity compares with the DCS system due to its connection with the network. That was for maintaining availability and reliability.
