PROFINET system presentation
PROFINET is the Industrial Ethernet standard of the PNO (PROFIBUS user organization). PROFINET IO describes the data exchange between controllers and field devices in several real-time classes: RT (software-based Real-Time) and IRT (hardware-based Isochronous Real-Time). In addition, further Ethernet traffic can be transmitted in the NRT (non-real-time) time slot of the PROFINET cycle. RT can be networked with commercially available switches; switches with corresponding hardware support are required for IRT.
