PLC Programming Best Practices - Benefits of Modular PLC Programming

Показать описание

In this video, I will be discussing the benefits of Modular PLC programming. The concept of modular programming and its benefits in creating well-structured and organized code will be explored. Modular programming involves dividing a complex system into smaller, more manageable components known as modules, which can be connected to form a complete and cohesive final product. To illustrate the difference between modular and non-modular programming, this article provides an example of controlling a motor using Programmable Logic Controller (PLC). Additionally, the article delves into the use of Add-On Instructions (AOIs) and User-defined Data Types (UDTs) in simplifying PLC programming and promoting modular programming. By using AOIs and UDTs, programmers can reduce programming time, simplify program maintenance, improve program readability, and reduce the likelihood of errors.
