This guideline presents an overview and guidance for the PROFINET documents. It
• explains the structure and content of the PROFINET specifications;
• relates the structure of the PROFINET specifications to the ISO/IEC 7498 OSI Basic Reference Model;
• shows how to use parts of the PROFINET specifications in combination with IEC 61784 1 and IEC 61784 2;
• shows the logical structure of IEC 61784 1, IEC 61784 2, and IEC 61784 5;
• provides explanations of some aspects of the PROFINET specifications that are common to many of the parts of IEC 61158 4, and, separately, to many of the parts of IEC 61158 5.

Application layer services for decentralized periphery and distributed automation Top

This specification provides the PROFINET Application layer service definition for the Communication Profiles (CPs) of PROFINET (Type 10). These specification was forwarded to IEC committee SC65C MT9 to build IEC 61158-5-10, 65C/435/CDV.

This standard is one of a series produced to facilitate the interconnection of automation system components. It is related to other standards in the set as defined by the “three-layer” fieldbus reference model described in
IEC/TR 61158 1.

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 standard defines the application service characteristics that fieldbus applications and/or system management may exploit.

Throughout the set of fieldbus standards, the term “service” refers to the abstract capability provided by one layer of the OSI Basic Reference Model to the layer immediately above. Thus, the application layer service defined in this standard is a conceptual architectural service, independent of administrative and implementation divisions.

Application layer protocol for decentralized periphery and distributed automation Top

This specification provides the PROFINET Application layer protocols for the Communication Profiles (CPs) of PROFINET (Type 10). These specification was forwarded to IEC committee SC65C MT9 to build IEC 61158-6-10, 65C/436/CDV.

This standard is one of a series produced to facilitate the interconnection of automation system components. It is related to other standards in the set as defined by the “three-layer” fieldbus reference model described in
IEC/TR 61158 1.

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 standard 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. These rules for communication are intended to provide a sound basis for development in order to serve a variety of purposes:
a) as a guide for implementors and designers;
b) for use in the testing and procurement of equipment;
c) as part of an agreement for the admittance of systems into the open systems environment;
d) as a refinement to the understanding of time-critical communications within OSI.

This standard is concerned, in particular, with the communication and interworking of sensors, effectors and other automation devices. By using this standard together with other standards positioned within the OSI or fieldbus reference models, otherwise incompatible systems may work together in any combination.

Profiles for distributed automation Top

This specification provides communication profiles (CP) for PROFINET CBA to the existing Communication Profile Family (CPF) of PROFIBUS and PROFINET. These CPs were forwarded to IEC committee SC65C MT9 to build IEC 61784-1, 65C/430/CDV.

This document provides a set of Communication Profiles (CP) in the sense of ISO/IEC TR 10000 1. These answer the need of identifying the protocol families co-existing within the IEC 61158 series, as a result of the international harmonization of fieldbus technologies available on the market. More specifically, these profiles help to correctly state the compliance to the IEC 61158 series, and to avoid the spreading of divergent implementations, which would limit its use, clearness and understanding. Additional profiles to address specific market concerns, such as functional safety or information security, may be addressed by future parts of this standard.

This standard contains several Communication Profile Families (CPF), which specify one or more communication profiles. Such profiles identify, in a strict sense, protocol subsets of the IEC 61158 series via protocol specific communication profiles. They do not define device-type-specific communica¬tion profiles for the purpose of guiding manufacturers in feature set selection – for example, in selecting the minimum set of communication services and protocol to implement a specific class of devices, such as generic slaves or transmitters ("implementation profiles"). Neither do they define device profiles that specify communication profiles together with application functions needed to answer the need of a specific application ("application profiles").

It is agreed that these latter classes of profiles would help the use of the IEC 61158 series of standards; the profiles defined in this document are a necessary step to achieve that task.
It is also important to clarify that interoperability — defined as the ability of two or more network systems to exchange information and to make mutual use of the information that has been exchanged (see 3.2.1 of ISO/IEC TR 10000 1) — can be directly achieved on the same link only for those devices complying to the same communication profile.
Profiles contained in this International Standard are constructed of references to IEC 61158 2 through IEC 61158 6 and other IS, TS or worldwide-accepted standards, as appropriate . Each profile is required to reference at least one (sub)part of IEC 61158 2 through IEC 61158 6.

Two or more Profiles, which are related to a common family, are specified within a "Communication Profile Family" (CPF).

Profiles for decentralized periphery Top

This specification provides additional communication profiles (CP) for PROFINET IO to the existing Communication Profile Family (CPF) of PROFIBUS and PROFINET. These CPs were forwarded to IEC committee SC65C WG11 to build IEC 61784-2, 65C/424/CDV.

These profiles meet the industrial automation market objective of identifying Real-Time Ethernet (RTE) communication networks coexisting with ISO/IEC 8802-3 – commonly known as Ethernet. These RTE communication networks use provision from ISO/IEC 8802-3 for the lower communication stack layers and additionally provide more predictable and reliable real-time data transfer and means for support of precise synchronization of automation equipment.

More specifically, these profiles help to correctly state the compliance of RTE communication networks with ISO/IEC 8802-3, and to avoid the spreading of divergent implementations.

Adoption of Ethernet technology for industrial communication between controllers and even for communication with field devices promotes use of Internet technologies in the field area. This availability would be unacceptable if it causes the loss of features required in the field area for industrial communication automation networks, such as:
• real-time,
• synchronized actions between field devices like drives,
• efficient, frequent exchange of very small data records.
These new RTE profiles may take advantage of the improvements of Ethernet networks in terms of transmission bandwidth and network span.

Another implicit but essential requirement is that the typical Ethernet communication capabilities, as used in the office world, are fully retained, so that the software involved remains applicable.
The market is in need of several network solutions, each with different performance characteristics and functional capabilities, matching the diverse application requirements. RTE performance indicators (see clause X5X), which values will be provided with RTE devices based on communication profiles specified in this document, enable the user to match network devices with application dependant performance requirements of an RTE network.

Subclause X5.1X specifies basic principles of performance indicators required to express RTE performance of a CP. Subclause X5.2 describes the view of application requirements. An application- dependant class could be used to find out a suitable CP. Clause 4 specifies how conformance of a device to the CPF or CP should be stated.
