Today, digital control technologies represented by PLC ladder diagrams are gradually replacing relays, which are products of the “bicycle era,” akin to “cars on the highway.” Although PLC ladder diagrams visually mimic the symbols of relay circuit diagrams (such as contactors, coils, etc.), their control logic has shifted from the “hardwired connections” of physical wiring … Read more

I remember when I first started in the industry, I took over a PLC program left by a former colleague, and it was a complete mess! There were no comments, variable names were arbitrary, and the program structure was chaotic. It took me three whole days to understand this program. This is why today I … Read more
I really can’t stand those newcomers in the industry who ask the most ridiculous questions every day. Just yesterday, a guy came to me with a textbook asking why his ladder diagram program wasn’t working. When I opened it, it was a mess of logical relationships, and he couldn’t even distinguish between normally open and … Read more
Click the blue text for more exciting information Once again, someone asked me about the safety of ladder diagrams, I really can’t believe it. Every time something goes wrong, they come to me only after the crisis has hit, if they had contacted me earlier, the workshop wouldn’t have had to stop production for three … Read more
