In a previous article, we discussed linear interpolation. Today, we will talk about arc interpolation. While linear interpolation is based on three-dimensional space (three axes), here we will focus on arc interpolation in two-dimensional space (two axes). 1. Schematic Diagram In a plane, our robotic arm needs to move from point A to point B … Read more
Hello everyone! Recently, a friend asked me why the Modbus communication between the PLC and the inverter was not working despite following numerous tutorials. I remember when I first started, I was just as confused, struggling with the wiring diagrams and making several mistakes in parameter settings before finally succeeding. Today, I will share the … Read more
In the field of industrial automation, equipment manufacturers (OEMs) often provide their proprietary communication protocols, such as Profinet, CIP, DeviceNet, and ControlNet, to facilitate communication between workshop devices. With the presence of controllers, instruments, and peripheral devices from different manufacturers, a question arises: how can data exchange be achieved among them? To address this challenge, … Read more
In the field of electrical automation, having strong technical skills is essential, but choosing the right city is equally important! A PLC engineer with 3 years of experience might earn 8K in a small city, while in Suzhou or Shenzhen, they can easily exceed 15K! Today, we will delve into the job demand and salary … Read more
Today, I will present an example of interference from a variable frequency drive (VFD) on a PLC’s analog signal and a solution using a signal isolation module to overcome such interference. 1. Example 1: Description of the Phenomenon In a Siemens PLC, an AO point outputs a 4-20mA current control signal to a Siemens VFD, … Read more
In the field of industrial automation, “SCADA” and “PLC” are two frequently mentioned terms, yet many people still struggle to distinguish between them. Some may ask: “Who is responsible for monitoring? Who is responsible for control?” Today, let us clarify this in a straightforward manner. What is SCADA? SCADA (Supervisory Control and Data Acquisition) is … Read more
Hello everyone, I am a veteran in automation with over 20 years of experience. Today, let’s discuss a practical topic: how to control inverters with PLCs to achieve soft start and speed regulation of motors.
