Abstract

This paper presents a design of Programmable logic Controllers which are well known for a long time that can be applied to be a controller for an automatic machine in industries. However, most of them have been imported from oversea country. This research focuses on the development of PLC by KMITL staff. This PLC system is consists of CPU unit, Digital I/O RTU unit, ANALOG RTU unit. The implementation of the CPU scan time and I/O refresh are principle to PLC. In this article, there are many benefits to industries especially in order to support SME that can use local technology. Therefore, we can apply this research to the manufacturing process in Thailand for the future.
