The PROFINET RTClasses used defines the type of real-time data exchange that is used by a PROFINET connection.
For the PROFINET developers, the Real Time class is set in the GSD file, under the tag=SupportedRT_Classes, or in the configuration tool of the controller. The classes are shown below:
- RT_CLASS_UDP = RT over UDP/IP (with this RT can be sent via a router, not used much up to now)
- RT_CLASS_1 = RT (for CC-A and CC-B)
- RT_CLASS_2 = IRT (depreciated and not used today)
- RT_CLASS_3 = IRT (used when motion or high-speed applications are necessary, CC-C)
