Tech & Buying Guide
Demystifying Programmable Logic Controllers: Comprehensive Guide to PLC Classification and Selection in Industrial Automation
Modern industrial automation heavily relies on Programmable Logic Controllers (PLCs) to drive factory floor efficiency. Over my 15 years as an industrial automation expert working with DCS, TSI, and control systems, I have seen PLCs evolve into the central nervous system of modern manufacturing. Selecting the right controller requires a deep understanding of PLC types based on physical size, hardware architecture, and power supply configurations.
Comprehensive Guide to PLC Types in Modern Industrial Automation
Modern industrial automation relies on programmable logic controllers to govern critical factory operations. System integrators classify PLCs based on scale, hardware architecture, and power supply design. Understanding these core categories enables automation engineers to select the right control system architecture. Consequently, proper hardware selection optimizes performance while minimizing long-term operational costs.
Demystifying the DDE Protocol in Legacy Industrial Automation Systems
Modern control systems rely heavily on seamless interprocess communication to exchange operational data between software programs. Microsoft first introduced the Dynamic Data Exchange (DDE) protocol in 1987 to enable real-time data sharing. In factory automation, DDE served as an early bridge between control software and Windows desktop applications. Therefore, understanding DDE mechanics provides crucial insights into how legacy industrial networks established software-level connectivity.
