S88.02 Data structures and guidelines for languages S88.02 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 S88.01: recipes, equipment capacities, scheduling and batch journals. The relational tables can be used for the exchange of information between different systems.
Data model, data structures and internal relations S88.02 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 S88.02 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 S88.02 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).
