This section identical with the international standard ISO 10303-11.2004 "Industrial automation and integration - Product data representation and cross In other Part 11. Description methods. EXPRESS language reference manual "(in English). This Part replaces GB/T 16656.11-1996 "Industrial automation and integration - Product data representation and exchange - Part 11. Description Methods. EXPRESS language reference manual. " Section compared with the GB/T 16656.11-1996 main change this as follows. This section provides EXPRESS language elements, each element of the language used in the respective Context example, said first describe simple Elements, and then ascending manner described in more complex concepts. This section is amended in order to meet the needs of multi-mode specifications, an overview of the new Read constitute the architecture scalable data model, this revision of this section adds the following keywords. --- BASED_ON; --- END_SUBTYPE_CONSTRAINT; --- EXTENSIBLE; --- GENERIC_ENTITY; --- RENAMED; --- SUBTYPE_CONSTRAINT; --- TOTAL_OVER; --- WITH. If the pattern in these key words as EXPRESS identifier, in this revised version of the model is invalid. In addition, the revision Version modified content to keep the previous version of upward compatibility. This section of the Appendix A, Appendix B, Appendix C, Appendix D, Appendix E, Appendix F and Appendix G are normative appendix, Appendix H, attached Record I, Appendix J, Appendix K, Appendix NA are informative appendices. This part is proposed by China Machinery Industry Federation. This part of the automation systems and integration by the National Standardization Technical Committee (SAC/TC159) centralized. This part mainly drafted by. China National Institute of Standardization. The main drafters of this section. Zhan Junfeng, Li Wenwu, Liu Shouhua, Liu Qing.

1 Scope

GB/T 16656 provisions of this part of the ability to define a language product data. This language is called EXPRESS. This section also provides graphical representation of EXPRESS language resources subsetting, which is called the graphical representation EXPRESS-G. In GB/T 16656.1 in EXPRESS is defined as a data description language. It consists of various language elements, allowing goes Ambiguous data definition, and data constraints defined will be described. This section applies to. ---type of data; --- Data constraint type instance. This section does not apply to. --- The definition of database formats; --- Definition file format; --- The definition of transmission formats; --- Process control; --- Information Processing; --- Exception handling. EXPRESS is not a programming language.
