PROFINET IO

PROFINET is a fieldbus standard of the PROFIBUS user organization that defines a
cross-vendor communications and engineering model.
As part of PROFINET, PROFINET IO is a communication concept that is used to implement
modular, distributed applications. PROFINET IO IRT allows defined response times and
highly precise plant behavior.
A PROFINET IO system consists of the following PROFINET devices:
● IO controller
Device used to address the connected IO devices.
● IO device
A distributed field device that is assigned to an IO controller.
The PROFINET IO controller operating mode allows direct access to IO devices via
Industrial Ethernet.
The PROFINET IO device operating mode enables you to operate S7 stations or distributed
I/O systems with a CPU as "intelligent" IO devices on Industrial Ethernet.
General properties of PROFINET IO
PROFINET IO provides the following properties and functions:
● Real-time communication (RT)
● Isochronous real-time communication (IRT)
● Prioritized startup
● Media redundancy
● Device replacement without exchangeable medium
● I-device
● IO controller
● Shared device
● Isochronous mode
