Tech & Buying Guide

Allen-Bradley AADvance Controllers provide advanced, modular control for complex industrial automation systems. Designed for both standard and safety-critical operations, they deliver powerful processing, flexible I/O, and scalable performance for next-generation process and factory automation.

Discover how SCADA systems revolutionize industrial automation by enabling remote control, data analysis, and real-time process optimization across industries such as power, water, transportation, and manufacturing.

Explore the four core functions of SCADA—data acquisition, communication, visualization, and control—and understand how this system powers industrial automation, process optimization, and remote supervision.

In modern industrial automation, three control systems dominate: Distributed Control Systems (DCS), Programmable Logic Controllers (PLC), and Remote Terminal Units (RTU). Each serves the same goal—monitoring and controlling processes—but is optimized for different applications and environments.

Loop checks are essential in the commissioning and maintenance of control systems. They verify that instruments, transmitters, and controllers within a process loop operate correctly. This article explains the fundamentals of loop checks, their types, and best practices in industrial automation environments.
