The oscilloscope is the most common instrument for electronic engineers, and many people compare it to the “eyes” of an engineer, which is enough to illustrate how important oscilloscopes are to engineers. How is the signal displayed on the oscilloscope screen? On the oscilloscope, the signal is transmitted through a series of resistors and capacitors … Read more
Introduction In industrial automation, analog signals are an important data type processed by PLCs, commonly found in measurements from sensors such as temperature, pressure, liquid level, and speed. Unlike digital signals that only determine ‘on’ and ‘off’, analog signals can represent continuous values. For example, the output from a temperature sensor may be a voltage … Read more
Basics of PLC Analog Signal Processing: Making Data “Speak” Hello everyone, I am Ouyang. Today, let’s talk about analog signal processing in PLCs. In automation control, analog signals act like the “senses” of devices, helping us accurately perceive and control various physical quantities. Mastering analog signal processing will make your PLC programs more flexible and … Read more
