This section is GB/T Part of 2,116,656. This section is equivalent to using the ISO 10303-21:2001 "Industrial automation systems and Integrated Products Part 21 data representation and exchange. the exchange of text encoding implementation structure "(in English), technical content and programming Write format ISO 10303-21:2001 is consistent.

This Part replaces GB/T 16656.21-1997 "Industrial automation systems and integration - Product Part 21 data representation and exchange.

Achieve text encoding method of the switch fabric. " Compared with GB/T 16656.21-1998 main changes are as follows.

--- Exchange current structure may comprise a plurality of data segments;

--- Header codes currently available for the switch fabric in the data segment entity instance string attribute identifies the default language;

--- Switch fabric header identification currently used to describe the semantics of information environment, an entity instance data block can be encoded in the Application of semantic environment;

--- If the short name is available, you can use the short name of the currently encoded enumeration values.

1 Scope

This section GB/T 16656 specifies the product data [using EXPRESS language (GB/T 16656.11) defines the conceptual model for Type] Clear text encoding of the exchange structure format. This file format is suitable for transmission of product data between computer systems.

This section provides mapping from EXPRESS language to language syntax of the switch fabric. EXPRESS diagram can be mapped to any post Change the structure of the system.
