Tech & Buying Guide

Selecting the correct control platform represents a foundational engineering decision in factory automation. System designers must carefully balance technical parameters against long-term operational requirements when implementing a Programmable Logic Controller (PLC). This article examines the critical evaluation metrics, physical scale classifications, and operational architectures of modern control systems.

The Programmable Logic Controller (PLC) remains the backbone of modern factory automation. Selecting the right controller requires a deep understanding of its hardware architecture and functional capacity. Engineers typically classify PLCs based on three primary criteria: physical size, hardware configuration, and power requirements.
