Although these services specify, from the perspective of applications, how request and responses are issued and delivered, they do not include a specification of what the requesting and responding applications are to do with them. That is, the behavioral aspects of the applications are not specified; only a definition of what requests and responses they can send/receive is specified. This permits greater flexibility to the FAL users in standardizing such object behavior. In addition to these services, some supporting services are also defined to provide access to the FAL to control certain aspects of its operation.
The IEC 61 1 58-5 series defines the services provided
a) to the various user(s) of the fieldbus application layer at the boundary between the user(s) and the application layer of the fieldbus reference model;
b) to systems management at the boundary between the application layer and systems management of the fieldbus reference model.
The IEC 61 1 58-6 series defines a number of distinct and non-interoperable fieldbus application protocols. Each protocol is most closely related to, and lies within the field of application of, the services of the corresponding part of the IEC 61 1 58-5 series.
7.4 IEC 61 784-1 and IEC 61 784-2 provide sets of communication profiles (CP) in the sense of ISO/IEC TR 1 0000-1 . These answer the need of identifying the protocol families co-existing within the IEC 61 1 58 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 IEC 61158.
IEC 61784-1 and IEC 61 784-2 contain 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 communication 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”).
