(1) Basic Instructions 1. Bit Logic Instructions Normally Open Contact ( -||- ): This instruction detects the input signal; the button is off when not pressed and turns on when pressed. For example, in the logic controlling the machine operation with the start button, pressing the start button closes the normally open contact, and the … Read more
In the field of industrial automation, the PLC (Programmable Logic Controller) is known as the “smart brain” of the equipment, controlling the orderly operation of the entire production process. However, when the indicator light on the PLC panel suddenly lights up, it often indicates that the system has encountered a problem, causing many engineers to … Read more
1. Basic Principles When establishing industrial Ethernet communication between SIMATIC S7-1200 or with other devices in automation projects, engineers need to understand what communication services the integrated Ethernet interface can provide, which communication protocols are supported, how many connection resources are available, and how to flexibly use communication instructions. The S7-1200 CPU integrates a PROFINET … Read more
The Baoxin Guangxi Hongwang project is the world’s first case of domestically produced PLC controlling a high-speed acid rolling mill. Prior to this, the Hongwang Hunan base had already conducted preliminary explorations, with its silicon steel base deploying the Baoxin PLC system, covering 15 production lines and over 100 control units. The order for Guangxi … Read more

In the realm of industrial automation, the PLC control system is hailed as the “smart brain” of equipment, precisely directing the operation of each machine. However, just like any powerful “brain,” a PLC can occasionally experience discomfort, and it inevitably encounters various faults during actual operation. If not addressed promptly, this can lead to production … Read more
Industry Prediction: When Edge AI meets large models, the oil and gas industry will give birth to a new species – Autonomous Energy Systems (AES). In the future, oil wells will not only be able to ‘self-diagnose’ but also autonomously optimize oil extraction plans based on geological data. Shell engineers candidly state: ‘Edge intelligent agents … Read more
