| Property | Value | Description |
|---|---|---|
| On Demand Poll Scheduler | additional properties | Configures the polling rates used in the on-demand polling
of imported histories. The topic, driver-HistoryPollScheduler documents these properties. |
| Default Rule | additional properties | Selects the stations
with histories to export and the history names to export from the
selected stations. The driver-ConfigRule component topic defines these properties. For details, refer to the Niagara Histories Guide By default, the parent container HistoryNetworkExt (History Policies) contains only the single Default Rule, which configures all exported histories with unlimited capacity. The system applies configuration rules only when it creates the history, that is, the first time it archives the history in the receiving station. Changing a rule has no effect on existing histories. The topic, “driver-ConfigRule” documents these properties. |
