HCAL can temporarily store export data in a store-and-forward cache. This is useful if the network connection to the historian on the AVEVA application is intermittent or unavailable. In such a situation, HCAL will store (cache) the export data. When the link becomes available again, HCAL will send the cached data to historian.
You have to specify the folder that HCAL will use for the cache. To do this, display the AVEVA Historic Data Export section of the Global Parameters branch in the Geo SCADA Expert Server Configuration Tool (see Accessing the Geo SCADA Expert Server Configuration Tool in the Geo SCADA Expert Guide to Server Administration). Use the Folder field within the Store/Forward section to specify the cache folder.
- Folder—Enter the full pathname of the folder that you want to use as a store-and-forward cache for export data. Use the Browse button to search for and then select a folder. An example pathname might be: C:\ProgramData\Schneider Electric\ClearSCADA\HCAL Store Forward.
