Connectivity Framework
2: Connectivity Framework
software components should support incremental evolution including upgrades, addition and removal of components. The connectivity function should also be able to support incremental evolution of the data exchange solutions during the lifecycle of a system.
2.3.7 INTEGRATION AND INTEROPERABILITY
IIoT systems comprise components that are often systems in their own right. The connectivity function should support the integration and the interoperability of system components, isolation and encapsulation of data exchanges internal to a system component, and hierarchical organization of data exchanges. In dynamic systems, the connectivity function should also support discovery of system components and the discovery of relevant data exchanges for system composition.
2.3.8 OPERATION
IIoT systems generally operate non-stop in a real-world environment. To support a system’ s operational needs, it should be possible to monitor, manage and dynamically replace connectivity elements. Monitoring includes health, performance and service-level characteristics of the connectivity function; management includes configuring and administering the capabilities; dynamic replacement requires replacement of hardware and or software while a system is operating.
2.3.9 SAFETY
A high degree of assurance is required in life- and mission-critical systems 1 to avoid unintended consequences during system operation. The connectivity function should be able to support safety evaluations and provide evidence required to make informed safety assessments.
