S7-400 One-Way Communication Based on PROFIBUS (STEP7 v1x)

The S7 protocol is the standard protocol used for communication between SIEMENS S7 series products. Its advantage is that both communication parties can establish a communication connection through the S7 protocol, regardless of whether they are on the same MPI bus, the same PROFIBUS bus, or the same Industrial Ethernet. The data exchange is independent … Read more

Understanding Hall Effect Sensors: Principles, Applications, and Arduino Interface

Hall Effect Sensors are magnetic field sensors made based on the Hall effect. When a constant current flows through the internal Hall semiconductor chip, a potential difference, known as Hall voltage, is generated in the perpendicular direction. This Hall voltage changes with the strength of the magnetic field; the stronger the magnetic field, the higher … Read more
