When the PLC output type is transistor type, it has a high-speed pulse output function. There are two forms of high-speed pulse output: one is Pulse Width Modulation, abbreviated as PWM; the other is Motion Control Output, abbreviated as PTO. This article introduces how to write PWM programs for the Siemens 200SMART ST30 PLC. PWM … Read more
In S7-200 SMART PLC programming, many beginners fall into the dilemma of “functionality achieved but program bloated”—when faced with requirements like “controlling the corresponding number of output bits based on stored values,” they tend to stack logic with numerous comparison instructions, making debugging cumbersome and subsequent modifications inflexible. This article starts from a real case … Read more

Introduction With the advancement of Industry 4.0, the Internet of Things (IoT), and smart manufacturing, standalone PLCs can no longer meet the complex production demands. They need to efficiently and reliably exchange data with more devices and higher-level management systems. At this point, a key “network hub”—the industrial switch—takes center stage. Many people believe that … Read more
Edge AI algorithms often require the combination of various features and signals as input. For example, calculating moving averages of time series over multiple different windows and passing them together to a machine learning model. Creative slicing and dicing of data can yield unexpected results. This article presents a general framework for data fusion in … Read more
