This part of GB/T 20720 specifies the general interface exchange content between manufacturing control functions and other enterprise functions: Tested

The considered interface is the interface between the layer 3 manufacturing system and the layer 4 business system in the hierarchical model defined by IEC 62264-1: Its purpose

It is to reduce the risks, costs and errors associated with implementing these interfaces:

Because IEC 62264 covers many fields and there are many different standards in these fields, the semantic description of IEC 62264 is

It is positioned so that other standards can be mapped to this standard: For this reason, IEC 62264 defines a set of general interfaces including

Elements, and the mechanism to extend these elements during implementation:

The scope of this section is limited to the definition of the object model and attributes of the exchange information defined in IEC 62264-1:

This section does not define attributes that describe object relationships:
