5 Communication Profile Family 1 ( F OUNDATION ® Fieldbus 7 ) 5.1 General overview Communication Profile Family 1 defines profiles based on IEC 61158-2 through IEC 61158-6, protocol Type 1 (Fieldbus Foundation), and on other standards. (See Table 10.) The F OUNDATION Fieldbus family of protocols consists primarily of two distinct protocol sets, known generically (for historical reasons) as H1 and HSE. The H1 profiles are a subset of IEC 61158 Type 1 services and protocols, and include both wire-media and fibre-media Physical Layers operating at 31,25 kbit/s. The HSE profiles are based on use of the ISO/IEC 8802–3 (Ethernet-like) MAC and Physical Layers, and on use of standard internet Network and Transport Layer protocols. A third profile set has been developed within the Fieldbus Foundation, but is not in current or planned use. It is included in this profile because it provides a migration path to CPF 1 from some of the CPF 5 protocols, and exclusion from this International Standard could inhibit that migration.
5.2.1.1.2 MAU and device classes Each MAU is classified according to its characteristics when interfacing to its associated medium, as specified in Table 12. For devices with a single attached MAU, whether separate or integral, the MAU class is also considered to be the device class. The selection of the proper clause of IEC 61158-2, Clause 12, Clause 16 or Clause 21, is based on the MAU class for which the MAU, and sometimes the associated device, are designed. The selection of Clause 21 is denigrated – not recommended for new designs – because the alternative clause, Clause 12, permits devices to lower their power consumption during periods of non- transmission. This profile also lists recommendations, which are not mandatory for implementation and/or not specified in IEC 61158-2, but are included to achieve interoperability amongst devices conforming to this profile. Specifically, 5.2.1.1.3.3 applies to each MAU, as does 5.2.1.1.3.4 for MAUs meeting IS rules.
