The installation and debugging of PLC control systems involve various tasks that must be performed in sequence. Each step is interconnected, and any oversight can lead to debugging failures, resulting in project delays or even equipment damage. This article presents the technical experiences summarized from on-site practices regarding the installation and debugging of PLC control … Read more
This design guide discusses how to design RS-485 interface circuits. It covers the necessity of balanced transmission line standards and provides an example of process control design. The article also discusses line loading, signal attenuation, failure protection, and current isolation under separate headings. 1. Why Balanced Transmission Line Standards are Necessary The focus of this … Read more
What Is Ultrasonic Testing DAC/TCG Curve? What Is Ultrasonic Testing DAC/TCG Curve? DAC Curve Concept: DAC=Distance Amplitude Curve The DAC curve, or “Distance-Amplitude Curve”, represents the relationship between the amplitude of echo signals and the distance of the ultrasonic waves. For defects of the same size, the echo amplitude varies due to different sound path … Read more
