When I first learned about PLCs, I found terms like “instructions” and “logic” to be quite abstract. It wasn’t until I started working on a marquee light program—watching the indicator lights illuminate step by step according to my written program—that I suddenly understood how to use timers and shift instructions. In fact, the marquee light … Read more
PLC programming is one of the essential skills for automation engineers. With this skill, engineers can effectively communicate with PLCs to guide their interaction with sensors and actuators in the factory workshop. Therefore, mastering the language of PLCs and the correct way to communicate is key to achieving efficient communication. This article will explore 5 … Read more
Hello everyone, recently many friends have left messages asking, what are the best methods to quickly learn PLC programming? This is a very good question. As the saying goes, “To do a good job, one must first sharpen their tools; sharpening the knife does not delay the work of chopping wood.” A good learning method … Read more
Currently, there are 5 standard programming languages for PLCs, including graphical programming languages and textual programming languages. Graphical programming languages include: Ladder Diagram (LD); Function Block Diagram (FBD); Sequential Function Chart (SFC). Textual programming languages include: Instruction List (IL) & Structured Text (ST). The programming languages of IEC 1131-3 are a set of international programming … Read more

This article will continue to explore the important part of this project, which is the automated control program. The automated control program … Read more
In PLC programming, the physical contact of the stop button is generally connected as normally closed, while in the program, it is written as normally open. This way, the stop button only serves as a signal in this equipment.Why is the emergency stop in PLC programming opposite to that of a regular stop button? In … Read more
