3.2.3 IRT
Isochronous Real Time
(IRT)
For PROFINET, an isochronous data exchange by the transmission of data
packages in regular time intervals of a few hundred milliseconds up to four mil-
liseconds is defined by the IRT (Isochronous Real Time) concept.
The beginning of a bus cycle is adhered to with the highest precision (jitter ≤1
µs). Each of the individual time intervals during the IRT communication is split
into an IRT interval and an open standard interval which requires the use of
special IRT switches.
