This report discusses the application of Programmable Logic Controller (PLC) control in a modem manufacturing industry, the programming approach in the ladder diagram design and development and the associated design software tools, namely the OMRON CX programmer, Automation Studio and LADSIM simulator. A case study on the development and simulation of a manufacturing plant process design was conducted to investigate for the viable and efficient approach in design and development of a PLC program. The usage of PLC has grown rapidly over the last 20 years to control process sequences ranging from small devices up to large process plant applications. This project is very much related to mechatronics and instrumentation design. Throughout this research, rigorous literature review on the basic method of programming a PLC programming and, the mechanical and the electronic devices used in the manufacturing plant design had been conducted to produce a reliable system for the design. Exposure to new design software such as Automation Studio and LADSIM has allowed simulations of the process sequences to be performed. In this research, the manufacturing process was divided into three sections of process control systems. Each section has its own programming sequences. In the final program, all the programming systems are integrated together to form a full programming system. The work provides the following main conclusions; the systematic and organized approach, as used in solving the sequential controls in a modem manufacturing plant, provides a better and flexible approach as well as better documentation. Although this research has been applied to a case study, however, the results and outcomes provide possible means of solving other similar systems or subsystems.
