What is BS EN IEC 62541‑9 about?
BS EN IEC 62541 discusses OPC Unified Architecture, a platform-independent, service-oriented architecture specification. BS EN IEC 62541‑9 details an efficient information model for conditions and alarms.
BS EN IEC 62541‑9 is the ninth part of a multi-part series that specifies the representation of Alarms and Conditions in the OPC Unified Architecture address space including their acknowledgment capabilities.
Under BS EN IEC 62541‑9, the Alarms and Conditions Information Model is designed in accordance with IEC 62682 and ISA 18.2.
Who is BS EN IEC 62541‑9 for?
BS EN IEC 62541‑9 on OPC Unified Architecture is relevant for:
- Technical providers
- Developers of industrial systems
- Developers of alarm systems
- Operators of OPC Unified Architecture
- Developers of OPC Unified Architecture
Why should you use BS EN IEC 62541‑9?
OPC Unified Architecture is a cross-platform, open-source standard for data exchange from sensors to cloud applications developed by the OPC Foundation.
BS EN IEC 62541‑9 assists you in maintaining the performance of your systems by providing the required conditions that represent the state of the system.
BS EN IEC 62541‑9 helps establish an efficient alarming system that informs the operator about conditions promptly and allows him to take immediate and necessary action before serious consequences occur.
BS EN IEC 62541‑9 can help in auditing, which is an important security and tracking concept.
By adopting BS EN IEC 62541‑9, you can establish an efficient information model of conditions and alarms can prevent consequences related to safety or physical and economic consequences and thus, can enhance the overall quality of OPC Unified Architecture.
What’s changed since the last update?
