PROFINET IO

PROFINET is a fieldbus standard of the PROFIBUS user organization that defines
a cross-vendor communication and engineering model.
Within the context of PROFINET, PROFINET IO is a communication concept for the
implementation of modular, distributed applications. PROFINET IO IRT enables defined
response times and high-precision system behavior.
The PROFINET IO controller operating mode enables direct access to IO devices
via Industrial Ethernet.
The PROFINET IO device operating mode enables the operation of S7 stations
as "intelligent" PROFINET IO devices on Industrial Ethernet.
UDP and RT or IRT are used to configure the cyclic IO data traffic for
PROFINET IO communication.
General properties of PROFINET IO
PROFINET IO has the following properties and functions:
● Real-time communication
● Isochronous real-time communication
● Media redundancy
● Prioritized startup
● Device replacement without exchangeable medium
