3.4.4 PROFINET IO
Properties of PROFINET IO
PROFINET is the open Industrial Ethernet standard of the PROFIBUS user organization,
which defines a cross-vendor communication and engineering model.
As part of PROFINET, PROFINET IO is a communication concept that is used to implement
modular, distributed applications.
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 enables direct access to IO devices via
Industrial Ethernet.
The PROFINET IO device operating mode enables you to operate S7 stations as
"intelligent" PROFINET IO devices on Industrial Ethernet.
The CPU uses PC interfaces for this purpose.
