From Ladder Logic to High-Level Programming: The Evolution of PLCs
Programmable Logic Controllers (PLCs) have been the workhorses of industrial automation since their inception in the late 1960s. Initially designed to replace hardwired relay systems, PLCs have evolved dramatically, transitioning from simple ladder logic programming to sophisticated high-level programming environments. This evolution reflects the demands of Industry 4.0, where flexibility, connectivity, and data-driven decision-making are…
