This part of IEC 61784 specifies
performance indicators supporting classification schemes for Real-Time Ethernet (RTE) requirements;
profiles and related network components based on ISO/IEC 8802-3, IEC 61158 series, and IEC 61784-1;
RTE solutions that are able to run in parallel with ISO/IEC 8802-3-based applications.
These communication profiles are called Real-Time Ethernet communication profiles.
NOTE The RTE communication profiles use ISO/IEC 8802-3 communication networks and its related network components or IEC 61588 and may in some cases amend those standards to obtain RTE features.
