When using historical data, there are cases where the user must select a single value from a time series of values, such as for loading initial conditions or Darwin Calibrator. The user usually needs data for a single point in time but a SCADA value may not be available at exactly that time. For example, the user may need a value for 8:00:00 but values may only be available for 7:58:14 and 8:02:11. SCADAConnect will use the value from the time closest to the time required.

However, there may be instances where the nearest value available is far from the required time. The user sets the band of time SCADAConnect will look for values by entering a Time Tolerance.

If there is no value within the time tolerance, no value is imported and an error message is listed in the SCADA Log which can be reached from Analysis > SCADAConnect Simulator > View Log button in Configure tab. The log message is written on attempting to read the signal value.
