OPC unified architecture - Part 24: Scheduler EN IEC 62541-24:2026

Publication date:   Mar 17, 2026

Scope

IEC 62541-24:2026 specifies an OPC UA information model to expose information, at what dates and times specific actions are executed by the OPC UA Server. Those schedules can optionally also be manipulated via the information model.

The schedule defines on which dates they are active, and can also reference global calendars representing specific dates, for example public holidays. In addition, the schedule defines times and actions that will be executed at that time. The model defines writing Variables and calling Methods but can be extended to other actions as well.

The NamespaceUri for all NodeIds defined in this document is defined in Annex A.
