Hello everyone, I am Xiao Chen. Today, let’s discuss a common issue that many PLC beginners encounter: why does a large number of ladder diagrams make the program seem bloated and difficult to maintain?In fact, while ladder diagrams are intuitive, programming purely with basic instructions is indeed inefficient.Mastering Function Block programming can make your PLC … Read more
Click the above to follow us! Is PLC Programming Challenging? Remember These 5 ‘Universal Templates’ for Beginners! I remember when I first entered the industry, standing in front of the PLC control cabinet, looking at the rows of wires and modules, my heart raced. At that time, facing the dense ladder diagrams felt like reading … Read more
The PLC control system, or Programmable Logic Controller, is a digital operation electronic device designed specifically for industrial production. It uses a type of programmable memory to internally store programs, execute logical operations, sequential control, timing, counting, and arithmetic operations based on user instructions, and controls various types of machinery or production processes through digital … Read more
Common Causes and Solutions for PLC Failures During OperationPART1.Peripheral Circuit Component Failures Such failures often occur after the PLC has been in operation for a certain period. If a component failure occurs in the PLC control circuit, the PLC control system will immediately stop working automatically. The input circuit is the port through which the … Read more
