What is IEC 61784-2- Fieldbus profiles for real-time networks used in industrial communication networks about?
IEC 61784 discusses industrial communication networks. IEC 61784-2 is the second part of the IEC 61784 multi-series and discusses additional Fieldbus profiles for real-time networks used in industrial communication networks based on ISO/IEC/IEEE 8802-3.
IEC 61784-2 specifies
- Performance indicators supporting classification schemes for Real-Time Ethernet (RTE) requirements
- Profiles and related network components based on ISO/IEC/IEEE 8802-3, IEC 61158 series, and IEC 61784-1
- RTE solutions that are able to run in parallel with ISO/IEC/IEEE 8802-3 based applications.
These communication profiles are called Real-Time Ethernet communication profiles.
NOTE: The RTE communication profiles use ISO/IEC/IEEE 8802-3 communication networks and their related network components or IEC 61588 and may in some cases amend those standards to obtain RTE features.
Who is IEC 61784-2- Fieldbus profiles for real-time networks used in industrial communication networks for?
IEC 61784-2 on additional Fieldbus profiles for real-time networks used in industrial communication networks based on ISO/IEC/IEEE 8802-3 is useful for:
- Industrial communication networks providers
- Communication network designers
- Automation department in industries
- Software companies
Why should you use IEC 61784-2- Fieldbus profiles for real-time networks used in industrial communication networks?
IEC 61784-2 provides additional Communication Profiles (CP) to the existing Communication Profile Families (CPF) of IEC 61784-1 and additional CPFs with one or more CPs. These profiles meet the industrial automation market objective of identifying Real-Time Ethernet (RTE) communication networks coexisting with ISO/IEC/IEEE 8802-3 – commonly known as Ethernet. These RTE communication networks use provision from ISO/IEC/IEEE 8802-3 for the lower communication stack layers and additionally provide more predictable and reliable real-time data transfer and means for the support of precise synchronization of automation equipment.
IEC 61784-2 provides you with basic principles of performance indicators required to express the RTE performance of a CP and guides you with application requirements. IEC 61784-2 also guides you with how conformance of a device to the CPF or CP should be stated.
