Maximum update frequency constraint; a 0 value means that no frequency limit should be set. It can only be used in order to lower the frequency granted by the Metadata Adapter. If not set, or negative, then no change of the update frequency constraint is requested; the case is useless, but reserved for future extensions.
The update frequency limit is obeyed only for MERGE, DISTINCT and COMMAND Items mode; in the latter case, the limit only applies to consecutive UPDATE events for the same key value.
If unfiltered dispatching has been requested for the Items, the change will be refused.
Edition Note: Note that a further global frequency limit could also be imposed by the Server, depending on Edition and License Type; this specific limit also applies to RAW mode and to unfiltered dispatching. To know what features are enabled by your license, please see the License tab of the Monitoring Dashboard (by default, available at /dashboard).
