标准范围

IEC 62541-10:20 20作为IEC 62541-10:20 20 RLV提供,其中包含国际标准及其红线版本,显示了与上一版本相比技术内容的所有变化。IEC 62541-10:20 20定义了与OPC统一架构中的程序相关联的信息模型。这包括节点类、标准属性、方法和事件以及程序的相关行为和信息的描述。IEC 62541-3中规定了包括所有节点类和属性的完整地址空间模型。IEC 62541 4中规定了服务,例如用于调用用于管理程序的方法的服务。这第三版取消并取代了2015年出版的第二版。与上一版相比,此版本包括几项澄清,此外还有以下重大技术变更:a)将ProgramType更改为ProgramStateMachineType。这符合节点集(以及实现)。在ProgramDiagnosticDataType中:更改了lastInputArguments和lastOutputArguments的定义,并为参数值添加了两个额外的字段。还将StatusResult更改为StatusCode。为ProgramDiagnostic2DataType创建了新版本的类型。b)将程序控制方法的可选建模规则更改为可选占位符。根据IEC 62541-3中的澄清,现在允许子类型(或实例)添加参数。

IEC 62541-10:2020 is available as IEC 62541-10:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62541-10:2020 defines the information model associated with Programs in the OPC Unified Architecture. This includes the description of the NodeClasses, standard Properties, Methods and Events and associated behaviour and information for Programs. The complete Address Space model including all NodeClasses and Attributes is specified in IEC 62541-3. The Services such as those used to invoke the Methods used to manage Programs are specified in IEC 62541 4. This third edition cancels and replaces the second edition published in 2015. This edition includes several clarifications and in addition the following significant technical changes with respect to the previous edition:
a) Changed ProgramType to ProgramStateMachineType. This is in line with the NodeSet (and thus implementations). In ProgramDiagnosticDataType: changed the definition of lastInputArguments and lastOutputArguments and added two additional fields for the argument values. Also changed StatusResult into StatusCode. Created new version of the type to ProgramDiagnostic2DataType.
b) Changed Optional modelling rule to OptionalPlaceHolder for Program control Methods. Following the clarification in IEC 62541-3, this now allows subtypes (or instances) to add arguments.
