Monitoring and Control of a Process by SCADA via Grafcet and Ladder Diagram Programming

This report discusses the development of a Supervisory Control and Data
Acquisition (SCADA) system for the monitoring and control of a process using
Programmable Logic Controller (PLC) via Grafcet and Ladder Diagram (LD)
programming. The report explains the background and several methods to program a
PLC. When dealing with a PLC, Grafcet is becoming the preferable method to work
with because of its easiness and the clear flow of program. In this work, the Tidal
Gate Control System (TGCS) is selected as a case study to investigate the advantages
and disadvantages of Grafcet over LD. A literature review to track the achievements
of researchers in using Grafcet and about Grafcet have been conducted. Procedure
and tools required to develop TGCS are elucidated. Results on the implementation of
the project are discussed. Programming the PLC to implement the monitoring and
control of TGCS via Grafcet is more convenient compared to programming via LD.
The recommendations on the future works of this project are also discussed.
