Overview and guidance for PROFINET specifications
IEC 61158-1

This document provides the overview and guidance how the IEC 61158 series is structured
and how it is related to the profile documents in the IEC 61784 series.

Version: 2.3
Order No.: 2.702
Language: English


Application layer services for decentralized periphery
IEC 61158-5-10

The application service is provided by the application protocol making use of the services available from the data-link or other immediately lower layer. This document defines the application service characteristics that fieldbus applications and/or system management may exploit.

Version: 2.4
Order No.: 2.712
Language: English



Application layer protocol for decentralized periphery
IEC 61158-6-10

The application protocol provides the application service by making use of the services available from the data-link or other immediately lower layer. The primary aim of this document is to provide a set of rules for communication expressed in terms of the procedures to be carried out by peer application entities (AEs) at the time of communication.

Version: 2.4
Order No.: 2.722
Language: English



Profiles for decentralized periphery
IEC 61784–2

This part of IEC 61784 provides additional Communication Profiles (CP) to the existing Communication Profile Families (CPF) of IEC 61784–1. These communication profiles are called Real-Time Ethernet communication profiles.

Version: 2.4
Order No.: 2.742
Language: English


Main difference to V2.3Ed2MU5 is the integration of Conformance Class “D” to specify PROFINET over TSN.


PROFINET V2.2  is specified in IEC61158-6-10 Ed2.0, IEC61158-5-10 Ed2.0 and IEC61784-2 Ed2.0.
