A Programmable Logic Controller (PLC) is a device that is capable of being programmed to perform control functions. The first PLC was introduced in the late 1960s to replace relay logic controls in the automotive industry. Compared to relay logic controls, the PLC's advantages include easy programming and installation, high control speed, hardware and software security, network compatibility, troubleshooting and testing convenience, and high reliability.
PLCs are currently used widely in industrial and commercial environments. They can be found in almost any manufacturing facility. There are several manufacturers of PLCs. While the instruction formats may not be the same for different brands, the hardware structures and programming concepts are very similar. This course is the first one of the two PLC courses. It covers PLC hardware structure, input/output modules, software, and programming. PLC operation and ladder logic programs are discussed in this course. Comparison Instructions, Math Instructions, and control instructions are covered in the following course.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
