Measuring Component Type Maximum Days to Estimate | Feature Configuration | Measuring Component Dates | Measurement Data | Start of Estimation Horizon |
---|---|---|---|---|
Not Configured | Not Configured | Not Set | None | Horizon will begin based on the installation date/time: • Interval uses the installation date/time • Scalar uses the On event |
Not Configured | Not Configured | Not Set | Yes, with some gaps | Horizon will begin based on the installation date/time: • Interval uses the installation date/time • Scalar uses the On event |
Configured | Any | Not Set | Any | Horizon will begin based on the process date/time less the Maximum Days to Estimate |
Configured | Any | Set | Yes - prior to Maximum Days to Estimate | Horizon will begin based on the process date/time less the Maximum Days to Estimate |
Configured | Any | Set | Yes - after Maximum Days to Estimate | Horizon will begin based on the Latest Contiguous Measurement Date/Time |
Not Configured | Configured | Not Set | None | Horizon will begin based on the process date/time less the hours configured on the feature configuration. If it is not yet time to estimate based on the calculated start of the estimation horizon, then: • Interval: Last Contiguous Measurement Date/Time is initialized to the calculated horizon start • Scalar: Last Contiguous Measurement Date/Time is initialized to the calculated horizon start and Adjusted Last Contiguous Measurement Date/Time is set to the appropriate value based on the periodic estimation configuration. Note: this would happen when the Hours Before Estimation (for example 72) is a larger number of hours than the No of Hours in the Past to Retrieve Last Usable Measurement (for example 24) |
Not Configured | Configured | Not Set | Yes - outside feature configuration window | Horizon will begin based on the process date/time less the hours configured on the feature configuration. If it is not yet time to estimate based on the calculated start of the estimation horizon, then: • Interval: Last Contiguous Measurement Date/Time is initialized to the calculated horizon start • Scalar: Last Contiguous Measurement Date/Time is initialized to the calculated horizon start and Adjusted Last Contiguous Measurement Date/Time is set to the appropriate value based on the periodic estimation configuration. Note: this would happen when the Hours Before Estimation (for example 72) is a larger number of hours than the No of Hours in the Past to Retrieve Last Usable Measurement (for example 24) |
Not Configured | Configured | Not Set | Yes - inside feature configuration window | Horizon will begin as of the most recent measurement date/time that was found for the measuring component. |
Not Configured | Configured | Set | Any | Horizon will begin based on the most recent of the following: • Process date/time less the hours configured on the feature configuration • Last Contiguous Measurement Date/Time |
