Devices that integrate the Profinet IO protocol. PROFINET (standardized IEC 61158 and IEC 61784) is oriented to applications concerning production automation, drives, automotive, food, packaging and logistics. Further application areas are emerging in the naval, energy and railway sectors. The use of PROFINET IO minimizes the costs of installation, design and commissioning of machines and plants. PROFINET IO also offers ease of expansion and high availability due to independent management of production units and low maintenance requirements.
