ANSI maintain registers of currently valid U.S. National Standards. This document has been prepared as part of the service of ISAThe Instrumentation, Systems, an

Toward this end, the Society welcomes all comments and criticisms and asks that they be addressed to the Secretary, St

10、al, and the International System of Units (SI) in particular, in the preparation of instrumentation standards. The Department is further aware of the benefits to USA users of ISA standards of incorporating suitable references to the SI (and the metric system) in their business and professional deali
11、ngs with other countries. Toward this end, this Department will endeavor to introduce SI-acceptable metric units in all new and revised standards, recommended practices, and technical reports to the greatest extent possible.

In the futur
17、e, additional methods may be defined to provide alternate ways to exchange 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 d
18、epiction that is ideal for all circumstances. 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
19、 is intended primarily for batch processes, there may be considerable value for other types of processes.This page intentionally left blank. 13 ANSI/ISA88.00.0220011 ScopeThis Part 2 standard on Batch Control defines data models that describe batch control as applied in the process industries, data
20、structures for facilitating communications within and between batch control implementations, and language guidelines for representing recipes.2 Normative referencesThe following normative documents contain provisions that, through reference in this text, constitute provisions this standard.

Used with permission of ISA.4.1 IntroductionThis clause defines data models that specify a set of objects, attributes, and their basic relationships that cover the c
39、oncepts of Part 1 at a high level of abstraction. The models apply to interfaces to batch control systems in a technology-independent manner. The models are not intended to address the internal system architecture of batch control systems.The intended use of these models is to provide a starting poi
40、nt for developing interface specifications for software components that address any subset of Part 1.The models address all of Part 1 as an integrated object model, but they do not presume or preclude any specific system architecture or information exchange. The models do not assume any specific div
41、ision of functionality between systems.In the cases where the objects and relationships defined in this clause are presented through an interface, then that interface shall use the object names, the attribute names, and the relationships of this clause commensurate with the interface technology chos
42、en and the capabilities offered. An example of such an interface is the SQL relational table interface that is defined in clause 5.An exchange format or interface specification may implement only some objects or parts of objects (e.g., not all properties are defined). An exchange format or interface
43、 specification may also provide additional objects or properties (e.g., phase duration information), including the expansion of any data model attribute into multiple attributes. Any such implementation shall be consistent with the data model that is presented here and the concepts of Part 1.4.1.1 M
44、odeling techniquesThe models that are described in this clause are based on the Unified Modeling Language (UML) (see clause A.1).The tables describe only the class attributes of the objects. The relationships between objects are described in the figures.4.2 Overview modelThis model (see figure 1) gi
45、ves a high level overview of the main classes that are defined and the relations between these classes for the batch domain that is described by the Control Activity Model of Part 1. The individual object classes are more thoroughly described in the subsequent models in this subclause. ANSI/ISA88.00
46、.022001 16 Figure 1 Overview modelA general or site recipe is made up of a hierarchy of general recipe entities that correspond to the procedural entities (process stages, process operations, and process actions). A master recipe may be derived from a general or site recipe. The master recipe itself
47、 may be seen as a top-level master recipe entity. A master recipe is made up of a hierarchy of master recipe entities that correspond to the procedural entities (i.e., procedures, unit procedures, operations, phases). A batch schedule entry specifies production of a specific batch through the execut
48、ion of a recipe. A batch schedule is, in principle, a list that specifies the production of batches, and it includes information about timing. The product-specific information necessary for this purpose is derived from a related master recipe entity. Based on a Batch Schedule Entry, a control recipe
49、 starts as a copy of a specific version of a master recipe, and it is then modified to create the recipe that will produce the batch. A control recipe includes the information necessary for equipment control.Control recipe entities are created based on master recipe entities. A control recipe may be enhanced with additional information (e.g., scaling, equipment assignment), and it may be modified (including creating or removing control recipe entities).Equipment entities are selected and allocated to the control recipe entities.
