Future of Programmable Logic Controller, Recent Trends, and Challenges

Abstract

Programmable Logic Controller (PLC)- based systems play a fundamental role in industrial automation, modern automated systems, and industrial control systems, monitoring, controlling, and optimising complex processes across modern industries. PLCs are digital computers specifically designed to operate in harsh industrial environments such as manufacturing plants, power stations, oil refineries, and transportation systems. Unlike conventional control systems, which rely on electromechanical relays and wiring, PLCs use programmable software and modular hardware, providing flexible, efficient, and reliable automation solutions. The use of PLC technology has significantly improved productivity, reliability, and safety in industrial operations.
