Automatic Data Repopulation
ADR, a standard Manager function, gathers selected data from device data logs to
repopulate database gaps caused by network or server outages. ADR will not repopulate
gaps in the database that are caused by loss of power to or failure of the metering devices.
ADR periodically reads data logs from the device and, inserts records in the database
where no corresponding data exists. It will not overwrite existing database records.
Devices that Support ADR
The following devices support Automatic Data Repopulation.
Allen-Bradley PowerMonitor 5000 Unit
The PowerMonitor energy and data logs provide the source for ADR. The energy log
collects a fixed collection of energy and demand parameters at a user-settable logging rate.
The data log content and logging rate are user-configurable.
Allen-Bradley Powermonitor 1000 Unit
The Powermonitor 1000 energy log contains a predefined collection of energy, status input
and demand parameters (depending on the model) logged at a user-configurable interval.
Allen-Bradley Powermonitor 3000 Unit
All communication networks are supported. The trend log is user configurable and holds a
variable number of records depending on the user configuration. The Powermonitor 3000
unit trend log should be configured to align with parameters and logging rate of
parameters being logged as meter tags.
ADR is designed to help assure the integrity of data for billing, cost allocation,
demand analysis and consumption reporting, such as real energy, reactive energy
and demand real power. Data not contained in the device snapshot, energy or trend
logs is not available for data repopulation.
Powermonitor 3000 unit trend log energy data is expressed with
7 digit precision while real-time energy data is expressed with 15
digit precision. For accurate reporting results when using ADR,
configure the Powermonitor 3000 energy counters to roll-over at
7 or 8 digits depending on your accuracy requirements. This
option is available with master module firmware version 1.12 or
higher. The rollover value in consumption meter tags must be
adjusted to match the actual energy rollover value.
