•Introduction: In industrial automation, PLC engineers often need to process raw data transmitted from low-level devices. When faced with the need to combine two 16-bit registers and interpret them as a 32-bit floating-point number (REAL), how can this be achieved efficiently? This article will use a sophisticated double-word conversion technique to uncover the secrets of hexadecimal-to-float...

 • In industrial automation, sensor signals are often affected by noise and interference, resulting in degraded system performance. Filtering algorithms are effective means of addressing these interferences, and the first-order lag filter is a commonly used signal smoothing technique. This article will explain how to implement and optimize a first-order lag filter in a PLC program to imp...
