PROFIBUS Physical Wiring and DP Connector Diagram From the diagram, it can be seen that when the switch is turned to “ON”, terminals A1 and B1 are connected to the termination resistor, so only A1 and B1 can be connected at the end of the DP network; otherwise, the termination resistor cannot be connected. When … Read more
Serial communication is the most basic communication method faced by electronic engineers, with RS-232 being the simplest form. However, many beginners often struggle to understand the relationship and differences between UART, RS-232, RS-422, and RS-485. This article will discuss these concepts to help clarify their relationships. Communication issues, like traffic problems, also have various scenarios … Read more
