Scope

GB/T 40305-2021 is the English-translated version of 现场设备集成 EDD与OPC UA集成技术规范.

GB/T 40305-2021 specifies how the electronic device description (EDD) of a field device is integrated with an OPC UA server. It sets out the integration architecture and its basic principles, the elements of the EDDL language, and an OPC UA device information model based on EDD, in block-based and non-block-based forms.

It then gives the rules for mapping EDD elements into OPC UA, including blocks, VARIABLE, ARRAY, RECORD and parameters, and the correspondence between EDDL and OPC UA data types, with an informative annex on the binary file format.

It is intended for system integrators, system suppliers and end users who bring field device data into upper-level applications. It was issued on 20 August 2021 and has applied since 1 March 2022.
