BS EN 61512-2 is the second part of the multiple series that defines data models that describe batch control as applied in the process 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 BS EN 61512-2. Refer to Annex B for a summary of all of the SQL definitions from clause 5.
BS EN 61512-2 on batch control languages is useful for:
A recipe element is a structural entity that is used to represent recipe entities and symbols, except transitions and directed links, that are used in procedure function charts
BS EN 61512-2 addresses data structures and guidelines for languages it is addressed by the data model. Data structures are also addressed by relational tables for information exchange. Languages are addressed by a recipe depiction methodology. BS EN 61512-2 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. BS EN 61512-2 specifies a method for the depiction of master and control recipe procedures that can be applied over a broader range of complexity.
Overall, BS EN 61512-2 provides a starting point for the development of interface specifications for software components
