PROFIBUS-DP (Process Field Bus - Decentralized Periphery) is a communication protocol used in industrial automation. It enables fast and reliable data exchange between programmable logic controllers (PLCs) and field devices like sensors and actuators. This protocol is designed for real-time applications, allowing for efficient control and monitoring of processes. The PROFIBUS standard supports a wide range of devices and is widely adopted in various industries, including manufacturing and process control. Its ability to connect multiple devices on a single network reduces wiring complexity and installation costs, making it a popular choice for automation solutions.
