37、 models and terminology applicable to batch control. Part 2 addresses data structures and guidelines for languages. Data structures are addressed by the data model that is defined in clause 4 that more precisely identifies objects and relationships that were addressed by models and concepts of part
38、1. Data structures are also addressed by relational tables for information exchange that are defined in clause 5. Languages are addressed by a recipe depiction methodology that is defined in clause 6. The intended use of the data model is to provide a starting point for developing interface specific
39、ations for software components that address any subset of part 1 of this standard. The data model addresses all of part 1 of this standard as an integrated object model, but it does not presume or preclude any specific system architecture or information exchange. The model does not assume any specif
40、ic division of functionality between systems. A specific method for the exchange of selected data is defined in clause 5. Relational tables are used as the information exchange method because, within the bounds of the information treated, they: utilise broadly available technologies; are amenable to
41、 translation to other technologies; are adequate; are consistent with other sections of the standard. Multiple methods of information transfer have not been defined, nor has there been an attempt to identify all information that might be exchanged. In the future, additional methods may be defined to
42、 provide alternate ways of exchanging data. Clause 6 defines the symbols and rules for a graphical language that can be used to depict recipes. Recipes are the central feature of batch control and they can address a wide range of complexity, but there is no one depiction that is ideal for all circum
43、stances. A simple table, for example, might be the most appropriate recipe form for simple cases. This standard specifies a method for depiction of master and control recipe procedures that can be applied over a broader range of complexity. Although this standard is intended primarily for batch proc
44、esses, it may be of considerable value for other types of processes. Page7 EN615122:200261512-2 IEC:2001 8 BATCH CONTROL Part 2: Data structures and guidelines for languages 1 Scope This part of this standard on batch control defines data models that describe batch control as applied in the process
45、industries, data structures for facilitating communications within and between batch control implementations and language guidelines for representing recipes. Refer to Annex A for an explanation of the UML notation that is used in this part of this standard. Refer to Annex B for a summary of all of
46、the SQL definitions from clause 5. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 61512. For dated references, subsequent amend- ments to, or revisions of, any of these publications do not a
47、pply. However, parties to agreements based on this part of IEC 61512 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of IEC
48、 and ISO maintain registers of currently valid International Standards.
