PROFINET (

work) is the open Industrial Ethernet Standard of Profibus & Profinet
International (PI) for automation. Profinet uses TCP/IP and IT standards, is real-time Ethernet
compatible and enables the integration of fieldbus systems.
The Profinet concept has a modular design, so that the user can choose the functionality himself. This
is basically different as regards the type of data exchange, to meet the requirements regarding the
speed.
For Profinet, there are the two perspectives Profinet-CBA and Profinet-IO:
Profinet-CBA (Component Based Automation) is intended for the component-based
communication via TCP/IP and the real-time communication for real-time requirements in modular
plant construction. Both ways of communication can be used in parallel.
Profinet-IO has been created for real-time (RT) and synchronous communication IRT (IRT =
isochronous real-time) with the decentralised periphery. The designations RT and IRT only
describe the real-time characteristics in the communication within Profinet-IO.
