Scope

This part of GB/T 21099 specifies the Electronic Device Description Language (EDDL), which is applicable to process control function blocks (FB). This part of GB/T 21099 considers the following factors to specify the function block (FB). a) The equipment model defines equipment components consistent with this standard. b) FB conceptual specification for measurement, execution and processing. It includes general rules for supporting the essential characteristics of control, avoiding details that impede innovation, and avoiding the specialization of different fields. c) Electronic Device Description Language technology that enables the integration of existing product details using engineering lifecycle tools. This part only defines a subset of GB/T 21099.1, and GB/T 21099.1 describes the general theory of the system aspect of the distributed system. Appendix B contains conformance statements relevant to this standard. The requirements in GB/T 21099.1 are not included in these declarations of conformity. FB is completed at the abstract level, which allows a variety of technologies to provide the definition of common features in a unique way, and also allows some supplementary feature definitions that meet user needs and that are expected to be implemented in the future. This abstraction is referred to here as a conceptual FB specification, and is mapped by industry organizations to specific communication systems and their additional definitions. This part is also based on the abstract definition of GB/T19769.1-2005. FDDL is intended to fill the gap between the conceptual FB specification and the actual product implementation. It allows manufacturers to use the same description method to describe devices based on different technologies and platforms. Figure 1 shows these aspects.
