| Summary: | With the vast utilization in industrial applications, Programmable Logic Controller has built a strong foundation in the industrial sectors. Having five programming languages being recognized by IEC61131-3, program developers have the freedom to opt for the languages that suit themselves as well as base on their prior basic knowledge about that language. However, the selection of languages will affects the effectiveness of a project or application and programmer should choose the language that suits the application the best. Having a PLC in controlling an electro-pneumatic actuating robotic mechanical arm, which programmed by LAD and SFC, this project aims to evaluate and study the use of these two languages in approaching industrial automation. With performance of the mechanical arm being analyzed as well as the program structures, conclusions are being made on the aspect of the suitability of the languages in approaching industrial applications, ease of use and shortcomings. This project explicit the steps in construction and transformation of a movement diagram and sequential chart into ladder logic and the simulation of the logic diagram. |
