How to Build an Edge AI Machine-Vision Inspection System

Introduction Manufacturing companies increasingly use machine vision to inspect products, identify defects, and improve production quality. Traditional inspection systems often depend on fixed image-processing rules, while modern systems can use artificial intelligence (AI) to recognize more complex patterns. Edge AI takes this technology one step further by running the AI model directly on an industrial […]

RS-485 Termination and Bias Resistor: Practical Calculation and Troubleshooting

RS-485 is widely used in industrial automation systems to connect PLCs, robots, PCs, remote I/O, sensors, and controllers. Although RS-485 is designed for reliable differential communication, incorrect termination, biasing, wiring, or grounding can cause intermittent communication problems. This article explains how to calculate the termination and bias resistors in a practical RS-485 network. 1. Basic […]

Industrial Communication Problems: Cable Connection, Impedance Matching, and Termination Resistors

In modern manufacturing environments, many machines and control devices must communicate with each other. A typical manufacturing system may include: PLCs Industrial robots PCs HMIs Servo drives Sensors Vision systems Motion controllers Remote I/O Industrial network switches These devices exchange data continuously through communication networks. When communication problems occur, engineers often focus first on software, […]
