(In the control room of a food packaging workshop, a small A frowns at the modules in the PLC control cabinet, while Zhang, holding a multimeter, approaches, accompanied by the sound of the packaging machine in operation.) Small A (pointing at the modules in the control cabinet): Zhang, when we learned about PLCs, we always … 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
PLC Interrupt Technology: High-Speed Counting Interrupt Applications for Accurate Microsecond Signal Capture! 🔥 The Hard Limitations of Traditional Scanning Cycles: A Nightmare for Microsecond Signals! Has your PLC program ever missed critical data because it couldn’t capture brief signals? Has the slow response of high-speed counters led to decreased production line accuracy and increased scrap … Read more
