适用范围：This standard specifies FB by using the result of harmonization work as regards severalelements:c) the device model which defines the components of an IEC 61804-2 conformant device;d) conceptual specifications of FBs for measurement, actuation and processing. Thisincludes general rules for the essential features to support control, whilst avoiding detailswhich stop innovation as well as specialization for different industrial sectors.This standard defines a subset of the requirements of IEC 61804-1 (hereafter referred to asPart 1) only, while Part 1 describes requirements for a distributed system.The conformance statement in Annex B, which covers the conformance declaration, is relatedto this standard only. Requirements of Part 1 are not part of these conformance declarations.The standardization work for FB was carried out by harmonizing the description of concepts ofexisting technologies. It results in an abstract level that allowed the definition of the commonfeatures in a unique way. This abstract vision is called here the conceptual FB specificationand mapped to specific communication systems and their accompanying definitions by theindustrial groups. This standard is also based on the abstract definitions of IEC 61499-1.
