Requirements for Standard Interface:

• The interface has to be capable of handling all of the kinds of manufacturing data.
• There must be no information loss while data is transferred among heterogeneous systems. In other terms, it should be possible to maintain the semantics throughout conversion.
• The system has to be capable of handling the real time requirements of a manufacturing system effectively and efficiently.
• The system must be open-ended to allow extensions or contractions.
• The system must be adaptable to other standards.
• The system should be independent of the computer and communication architecture utilized.
• The systems must be capable of handling maximum number of data entities. Ideally, there should not be any limitation.
• It should be possible to form application-oriented subsets of the standard to decrease cost and overheads.
• The system must be capable of attaining production data.
• The interface should be upward and downward-compatible in a hierarchical control structure.
• Test procedure should be provided to check the efficiency and accuracy of data transmission.
