Previously, a colleague privately messaged me to create a tutorial on Siemens OPC UA. Recently, I have been quite busy and did not have time to set up the system for testing and verification. Today, I happen to have some free time, so I will create an article about Siemens OPC UA, covering both the … Read more
Abstract: Virtual debugging technology is revolutionizing the execution of industrial automation projects. It connects PLC control programs with robot simulation models in a virtual environment, completing most debugging work before actual hardware deployment. This article will detail the process and key technical points of virtual debugging using mainstream simulation software in the industry as examples. … Read more
In the previous issue, we outlined the common industrial control devices and software systems in Industrial Control Systems (ICS). Today, we will explore the communication protocols between devices and software systems. Before we begin, let’s first understand the topological access relationship between control devices and software: refer to the hierarchical model division of IEC62264-1: L4 … Read more
1. Core Communication Protocols: The Engineer’s Toolbox We categorize the most commonly used communication methods into three main types to facilitate quick selection in your projects. First Type: The most integrated and mainstream “one-stop” solution 1. PROFINET (Key Focus) This is the absolute mainstream and preferred choice for Siemens S7-1200/1500/400 series, representing the implementation of … Read more
Process optimization, predictive maintenance, manufacturing services, adaptive systems, resource savings, smart factories, and cost reduction—there are limitless benefits to adopting control network data at higher-level systems. The Internet of Things (IoT), Industry 4.0, and China Manufacturing 2025 all mention that seamless, continuous, and standardized communication is universally required across various levels. Sensor data is uploaded … Read more

1. Currently, ABB has upgraded the tools configured with OPC UA to IOT GATEWAY, which can be downloaded and installed.2. Open RobotStudio and create a robot system. For systems above RW6.10, the OPC UA option is required. For RW7 robots, the 3154-1 IOT Data Gateway is needed. 3. To control the robot movement via OPC … Read more
Search on WeChatTechnical Training OPC UA Client and Server is a software tool used for implementing data communication in industrial automation systems. By using the OPC UA communication protocol, real-time data exchange and logging can be achieved between different protocols. OPC UA (OPC Unified Architecture) is an open, cross-platform communication protocol that provides a standardized … Read more
LoRaWAN (Long Range Wide Area Network) is a low-power wide area network (LPWAN) protocol specifically designed for the Internet of Things (IoT). It was established by the LoRa Alliance in 2015 and became an officially recognized LPWAN standard by the International Telecommunication Union (ITU) in 2021. The following is a comprehensive analysis from the perspectives … Read more
Hello everyone, I am Maple Leaf, and I have been in the PLC industry for over twenty years. Today, let’s talk about something practical—PLC communication essentials. To be honest, communication issues in the field are the most common type of faults I encounter, without exception! Many novice engineers have stumbled in this area, including myself … Read more
