IEC 62264-2:2013 specifies generic interface content exchanged between manufacturing control functions and other enterprise functions. The interface considered is between Level 3 manufacturing systems and Level 4 business systems in the hierarchical model defined in IEC 62264-1. The goal is to reduce the risk, cost, and errors associated with implementing the interface. This second edition cancels and replaces the first edition published in 2004 and constitutes a technical revision. It includes the following technical: - addition of object models for exchange information used in manufacturing operations management activities; - displacement of the UML object models that were in IEC 62264-1:2003 into this standard so that the object models and the associated attribute tables were available in the same document; - addition of the Hierarchy scope object definition to replace the Location attribute used in the previous edition; - addition of a value type section to define the exchange of non-simple value types; - definition of simple value types were defined using the ISO 15000-5.
