PROFINET protocol family
PROFINET is a set of fieldbus protocols which were introduced several years ago and are developed by the PROFIBUS Nutzerorganisation e.V. (PNO), see: http://www.profibus.com
All the PROFINET protocols are based on standard Ethernet.
There are two PROFINET "flavours" available, IO and CBA (which are independent of each other) and some related "helper" protocols.
PROFINET/CBA: distributed automation.
PROFINET/DCP: discovery and basic configuration.
PROFINET/IO: decentralized periphery.
PROFINET/MRP: media redundancy protocol.
PROFINET/PTCP: precision time control protocol.
PROFINET/RT: real time data transfer.
PROFINET/IRT : isochronous real time data transfer
