Click the little blue text to follow! Last week, during a safety assessment at an automation factory, I witnessed their equipment experiencing an inexplicable shutdown. The manager looked worried and said, “This is the third time this month, and each shutdown costs us over a hundred thousand.” Where is the problem? After inspection, I found … Read more
In PLC programming, there are various flow control structures used to organize code, implement logical functions, and decision-making processes. When using ST (Structured Text), a programming language defined by the IEC 61131-3 standard, we can utilize control structures similar to those in high-level programming languages. Below are some commonly used flow control structures in ST … Read more
At the end of this article, there are 55 practical case materials. Introduction:In automation equipment, each device has its actions, such as what to do first and what to do next, which are logically related. Just like in our daily lives, we need to have a sequence of actions to maintain order. For example, we … Read more
Search WeChatTechnical Training Approaches are also ideas, and the common programs we usually see can be summarized intotwo approaches. 1. Use coil outputs for output points, with only one occurrence in the program. 2. Directly control output points using set and reset, with one output point appearing multiple times in the program. What approaches do … Read more
We are learning about programming continuous control programs. Before writing the program, the first step is to create a project, add devices, and save the project. Next, open the “Default Variable Table” under “PLC Variables” in the project tree on the right.In the default variable table, we add variables, which means we add comments to … Read more
