ISA-88.02
Data structures and guidelines for languages
ISA-88.02 consists of data models, tables and a standard method for depicting recipes. The data exchange models treat four important aspects of information that are described in ISA-88.01: recipes, equipment capacities, scheduling and batch journals. The relational tables can be used for the exchange of information between different systems.
Data model, datastructures and internal relations
ISA-88.02 defines data models that specify a set of objects, attributes and their basic relationships that cover the concepts of Part 1 at a high level of abstraction. The intended use of these models is to provide a starting point for developing interface specifications for software components. The models address all of Part 1 as an integrated object model, but they do not presume or preclude any specific division of functionality between the systems.
Guidelines for languages
ISA-88.02 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 circumstances. The ISA-88.02 standard specifies a method for depiction of master and control recipe procedures that can be applied over a broader range of complexity, called Procedural Function Chart (PFC).
