Behavior Trees (Bt) In Plc And Automation Controllers: A Modular Approach To Intelligent Industrial Automation

Abstract

Behavior Trees (BT) are increasingly emerging as a robust methodology for structuring control logic in automation systems, particularly in programmable logic controllers (PLCs) and advanced industrial controllers. Unlike traditional sequential or ladder-based programming paradigms, BTs offer modularity, scalability, and clear task hierarchies, making them ideal for complex, dynamic, and autonomous industrial operations. This paper explores the foundational concepts of Behavior Trees, their integration into PLC-based automation systems, and the potential benefits and challenges associated with their deployment. The discussion further extends to the practical implications for industries aiming for adaptive and intelligent automation frameworks.
