You use the Historic check box within the Profiles section of each DNP3 SCADAPack Point Form to specify whether Geo SCADA Expert is to store profile data historically.
When the Historic check box is selected, Geo SCADA Expert will store historically the data for any enabled Daily (DNP3 SCADAPack) profiles, or configured Standard profiles (depending on the type of Profile used by the point).
As Profiles have a one-minute resolution, Geo SCADA Expert will store the value of each profile historically, once per minute, providing that:
- The point is In Service
- The point has valid configuration
- The profile’s value has changed from its previously stored value.
The data that Geo SCADA Expert stores historically comprises the profile data that is configured in the Geo SCADA Expert database. Whenever a profile’s configuration is changed in Geo SCADA Expert, those changes have to be downloaded to the outstation in order for that outstation to use the new profile data. With historically stored profile data, the stored data will differ from the actual profile used by the outstation for the period between any configuration changes being saved in Geo SCADA Expert and those changes being downloaded to the outstation.
