What is BS EN IEC 62541‑10 about?
BS EN IEC 62541‑10 is the tenth part of the OPC unified architecture multi-series standard. It deals with the programs associated with OPC unified architecture.
BS EN IEC 62541‑10 defines the information model associated with programs in the OPC unified architecture. This includes the description of the Node Classes, standard properties, methods and events and associated behaviour and information for programs.
Who is BS EN IEC 62541‑10 for?
BS EN IEC 62541‑10 on OPC unified architecture programs is applicable to:
- Organizations shifting to service-oriented architecture
- Software development teams
- Cybersecurity teams
Why should you use BS EN IEC 62541‑10?
OPC unified architecture is an interoperability standard for transferring data securely and reliably in industrial automation and other industries. It is a platform-independent, service-oriented architecture that ensures a smooth flow of data across devices from various manufacturers.
BS EN IEC 62541‑10 gives you information on concepts such as security considerations, program finite state machine, program states, state transitions, program state transition stimuli, program control methods, result data, program lifetime which allows you to set up OPC unified architecture programs for operational connectivity and enhanced security.
What’s changed since the last update?
BS EN IEC 62541‑10:2020 supersedes BS EN 62541‑10:2015, which is now withdrawn.
Changes in BS EN IEC 62541‑10:2020 includes –
- Changed Program Type to Program State Machine Type which is in line with the NodeSet. In Program Diagnostic Data Type: changed the definition of last Input Arguments and last Output Arguments and added two additional fields for the argument values. Also changed Status Result into Status Code. Created new version of the type to ProgramDiagnostic2DataType
- Changed Optional modelling rule to Optional Place Holder for Program control Methods. Following the clarification in IEC 62541-3, this now allows subtypes (or instances) to add arguments
