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.

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.

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.

***************************************************************************************************************************************************************************************

V2.4MU3 mainly focuses on three topics
1. Complete security integration (aligned to IEC/IEEE 60802)
2. IEC/IEEE 60802 conformant end station, bridge, and bridged end station model
3. Enhancements for APL support – avoiding congestion loss

The device model derived from IEEE 802.1Q and a more stringent decoupling of PROFINET
middleware and network interface lead to structural changes in the documents.
➔ This process will be completed in the MU4 with the IEC/IEEE 60802 integration
Complete security integration in Profile, Service and Protocol for all conformance classes.
➔ This process will be completed in the MU4 with the IEC/IEEE 60802 integration
Mixed link speeds are identified as a major threat for creating congestion loss.
➔ Congestion loss prevention completed

 

Main topics for V2.4MU4:

Add application classes Drive and Encoder.

Add Downshift delay and Expected PHY latency variation.

Allow full range for StreamDA destination MAC address.

Adjustment of the DCP filter chaining function.

Adaptation the definition of the required bridge resources to the link-speed and the mandatory buffer time.

Allow the use of link-local IP address according to RFC 3927.

Update the LLDP EXT MIB for MRP interconnection.

Clarification of MRP interconnect encoding.

The IP parameter of the DCP ASE value distinguish between operational and administrative.

Security:

New optional record SNMPReal.

VCI extension for IDevID credentials; used for automated credential commissioning.

Simplify addressing of credential used in record services.

 

 Main topics for V2.4MU5:

Update meaning of the coding of the CycleCounter field for update intervals > 32 ms allowing a more reliable detection of timeliness of data.

Add convention for how to implement adjustable MAUType wit link speed > 100 Mbit/s.

Clarification for PRUNING features according to IO controller, IO devices and bridges.

Security:

Enable RT_CLASS_3 for secure communication.

Introduce new symmetric key update,  adapt AR startup accordingly .

Add security eventing with predefined auditable events for PROFINET and SYSLOG style.

Refinement of related security state machines.

Define ResetToFactory behavior to reset security configuration.
