Discovering and matching histories
Unless working offline, you can use the learn process to export histories in the station.
Prerequisites: You are connected to a station.
- Expand the right-click the Histories node in the Nav tree and click .The Niagara History Export Manager view displays the histories in the (local) station that are candidates for export.
- Click the Discover button.The top Discovered pane is a collapsed tree structure of all discovered local histories organized by station name.
Histories under the same station name as the local station originated in that local station. Histories under any other station nodes represent histories currently imported (or exported) to the local station.
The Database (bottom pane) lists history export descriptors and history system export descriptors currently in the station database.
- Click to expand, select the histories to export and click Add.A window opens that allows you to edit properties before the history export descriptor(s) are created in the station.
The Add button is available in Learn Mode when you have one or more items selected (highlighted) in the top Discovered pane. The Add window is identical to the history export descriptor Edit window.
- Edit the properties and click OK.The station creates history export descriptors under its Histories container.
- Each NiagaraHistoryExport descriptor has a one-to-one associated history, exported to that remote station.
- Each NiagaraSystemHistoryExport descriptor may, and often does, result in many associated exported histories in the remote station. Note in the Database
pane you can spot these export descriptors by the blank
History Idvalue, as well as a text value in the System Tag Patterns column.
- As necessary, drag the border between the two panes to resize.
- At any time, to toggle between the two-pane Learn Mode and the single-pane (Database) view click the Learn Mode tool in the toolbar or use the Learn Mode command in the Manager menu.
