PROFINET (Process Field Network) is a high-performance Industrial Ethernet standard designed for automation technology. Managed by PROFIBUS & PROFINET International (PI), it serves as the Ethernet-based successor to the PROFIBUS fieldbus.
PROFINET utilizes standard TCP/IP protocols for non-time-critical tasks, such as configuration and diagnostics, allowing it to coexist with standard IT traffic on the same network. However, for demanding machine control tasks, it uses a real-time communication channel that bypasses the TCP/IP stack to ensure high speed and determinism. Its flexible architecture supports various network topologies (line, star, ring) and simplifies the integration of devices from different manufacturers.
PROFINET for Power Supplies Equipping a programmable power supply with a PROFINET interface allows it to function as a fully integrated component within a modern automation system. This enables PLCs to control and monitor the power supply with high precision and speed, making it ideal for complex, synchronized manufacturing or testing processes.
