General information
PROFINET is defined by the PROFIBUS user organisation. You can differentiate between the
PROFINET component model (CBA = Component Based Automation) and the PROFINET IO.
The PROFINET component model is used for the component-based communication via
TCP/IP and the real time communication for real-time requirements in modular system
engineering.
PROFINET IO has been developed for real-time and synchronous communication IRT (IRT =
Isochronous Real Time) with decentralised peripherals. The designations RT and IRT only
describe the real-time communication features within PROFINET IO.
Tip!
Detailed information on PROFINET can be found on the website of the PROFIBUS
