PROFINET IO is a standard adopted by PROFIBUS International relating to the communication of I/O controllers (PLC) with I/O devices (field equipment). The technology is based on the Ethernet as the communication medium and serves the purpose of transferring I/O data, parameters, alarms etc.


A difference is made between real-time applications (PROFINET RT) with cycle times of 5 to 10 ms or PROFINET Isochronous Real-time (IRT) for high-performance applications with bus cycle times in the range of 1 ms. For IRT applications, the I/O devices require switching functionality, i.e. special chipsets must be used.
