Programmable Logic Controller (PLC) has been widely used in the industrial world. It ease of usage and minimal in size make it the best option to replace the function of the old analogue circuit which is spacious and very complicated. This project has been dedicated to study the PLC usage in KLIA Aviation Fuel terminal and to observe any room for improvement in PLC usage. Thus, throughout the details study, it was found out that the ability of the PLC is not fully utilized for the fuel terminal fast flushing o. eration. This project has been focusing in this area and amodel of its implementation will be developed within the given timeframe. This project is basically focusing on replicating or to imitate aPLC functions in a real industrial processes. Thus, astudy was carried on the current system used in KLIA Aviation Fuel Terminal. The main objective of this project is to establish aone click solution for KLIA Aviation Fuel Terminal Fast Flushing Operation using the available equipments in UTP. Thus, the operator will only have to click one single button in the Graphic user Interface :C-UI) at the SCADA program screen which represents the different section. With just ore click, the program will instruct the PLC to control the appropriate pumps and notorized operating valve (MOV). Moreover, this program is accessible thru any internet communication link. Thus, the operation can be carried out from other places with internet access instead ofthe Operation Control Room. The scope of this project is divided into six major areas. The first part is to understand the whole system and then narrow down the scope toward amore focus area namely the Fast Flushing Operation (FFO). Secondly, it is necessary to understand the fonct.cn of the available PLC and then focus on the programming works by ^amputating the particular software. The third phase focused on setting up the PC-based s> item. The main task of this step is focusing on linking the Computer and PLC to prepare the basic platform for the total system. Next, in the fourth phase, the focus is to develop the Graphic User Interface (GUI). In the fifth phase, the GUI and the PLC will be integrated and tested as a system. Phase six will be focusing on setting up the web based structure of the system. In general, this project is a combination ofhardware and software which is integrated to each other to become a complete system. Various methods of research have been used to carry out this project. Basically, it may be classified into three main methods. The methods are Case Study or Field Study, Desk Study and Project Milestone. All the three methods were used throughout the project in order to collect relevance data, understanding the hardware and software etc. Project Milestone play the role asan indicator ofthe project achievement.
