PROFINET is an industrial communication standard used for automation and control systems. It enables devices like sensors, actuators, and controllers to communicate with each other in real-time over Ethernet networks. This standard is designed to support various applications, from simple data exchange to complex motion control. One of the key features of PROFINET is its ability to provide high-speed data transfer and deterministic communication, which is essential for time-sensitive operations in manufacturing. It also supports both TCP/IP for standard data communication and RT (Real-Time) for time-critical tasks, making it versatile for different industrial environments.
