Scope

IEC 61784-2:2019 specifies the performance indicators supporting classification schemes for Real-Time Ethernet (RTE) requirements; the profiles and related network components based on ISO/IEC 8802-3 or IEEE 802.3, IEC 61158 series, and IEC 61784-1 and the RTE solutions that are able to run in parallel with ISO/IEC 8802-3 or IEEE 802.3 based applications. These communication profiles are called Real-Time Ethernet communication profiles. This fourth edition cancels and replaces the third edition published in 2014 and constitutes a technical revision. The main changes are:
• update of reference from ISO/IEC 8802-3 to ISO/IEC/IEEE 8802-3;
• update of the dated references to the IEC 61158 series, to IEC 61784 1, to the IEC 61784-5 series and to IEC 61918 throughout the document;
• update of selection tables for CPF 2, CPF 3, CPF 4, CPF 8 and CPF 17;
• CPF3: update of the requirements for all conformance classes;
• CPF3: updated timing requirements for IO devices;
• CPF3: refining the added application classes;
• addition of a new Communication Profile Family – CPF 20 in Clause 21;
• addition of a new Communication Profile Family – CPF 21 in Clause 22
