As a PLC programmer, what is the first thing we should do when we receive a project? Many might say to review the process programming, but it is far from that simple. There are many tasks to complete before you start programming. Many PLC programmers often take over projects from others, and they find it … Read more
In the vast realm of PLC engineering practice, projects often resemble complex mazes, with numerous input and output points acting as checkpoints within the maze. Have you ever been troubled by a sudden failure of a physical point in your PLC? When such situations arise, if the program is directly bound to the actual I/O … Read more
IntroductionIn PLC learning, many people fall into the trap of “piling up instructions”—memorizing the usage of timers and counters but unable to create a stable quiz buzzer. In fact, the quiz buzzer seems simple but hides the core logic of industrial control:signal priority judgment, interlocking to prevent conflicts, and state reset management. Today, we will … Read more
Length measurement, or distance measurement, is ubiquitous in industrial production. This article presents a programming method for continuous length measurement using the SIEMENS SIMATIC S7-1200 connected to the OMRON E6B2-CWZ5B incremental encoder, based on a practical case. The goal is to achieve cyclic measurement, length counting, and subsequent speed measurement with minimal and straightforward programming. … Read more
