Database
Daily Schedules
The first step is to define daily schedules.
Each schedule needs to be defined, configured,
and put on-line.
Monthly Schedules
The next step is to define monthly schedules.
Each schedule needs to be defined, configured,
and put on-line. Each day of
the month must be assigned
a daily schedule, or set to NONE.
Meters
Finally, one must first define, configure,
and put on-line one or more meters.
Each meter must be assigned
a monthly schedule.
Data Processing
Number of Bits
parameter of each RUEX counter involved in meter reading must be correctly
specified, otherwise dial reading calculations fail the first time the counter
rolls over after associated meter is calibrated.
Pulses per Disk Revolution,
Wh per Disk Revolution (Kh), and Dial
Reading Multiplication Factor meter parameters must be specified correctly
for dial reading calculations and downloaded data rescaling to be correct.
The Number of Digits
meter parameter must be specified correctly, otherwise dial reading
calculations fail the first time meter dial rolls over after the meter is
calibrated.
Data Recording
NTMCRDR is enabled on all
meters by default. One can disable
or re-enable NTMCRDR on any one meter at any time.
To start RURDR data recording on all meters one must:
- Define the RUEX
domain data recording interval, making certain that the Data Recording Interval Authority
on each remote unit is set to Domain.
- Enable data recording on all
meters.
To (re)start data recording on a single meter one must:
- Define the RUEX
domain data recording interval, making certain that the Data Recording Interval Authority
on each remote unit is set to Domain. This step must be taken only
if it was not done when starting data recording on all meters.
- Press the Enable Demand
Recording button in the meter window.
Data Archiving
One has to periodically archive data and event logs. Both operations are
manually initiated by the operator.
Archiving of NTMCRDR files is initiated by executing the MREX Archive
NTMCRDR Files command. The accumulating data files get appended to
the corresponding archives located in the NTMCRDR
archive directory.
MREX relies on RUEX for RURDR, so archiving
of those files is initiated by executing the
RUEX Archive
Data Recording Files command. The accumulating data files get appended to
the corresponding archives located in the RURDR
archive directory.
Event log archiving is initiated by executing the MREX Archive
Log File command. The accumulating event log file gets copied to the
NTMC event log archive directory, common to all NTMC
components, and reset to empty.
Data recording files and event log file can be periodically
archived automatically if so desired. Care must be taken that archive
directory is always available and in the same place, otherwise archives are
scattered in different locations, and historical searches become inconvenient.
Meter Reading
In addition to the setup discussed in the Database
section above, the following must be defined and performed in order for
automated meter reading to function on a given day.
In all cases:
- MREX must be enabled.
- Meters must be enabled.
- Meters must be calibrated.
- Monthly schedules must be enabled.
- Monthly schedules must have properly defined (see below) daily
schedule(s) assigned
for that day.
- Daily schedules must be enabled.
Latest Dial Reading
- Daily schedules Non-billing Read parameters must be enabled.
- Daily schedules Non-billing Read Time of Day parameters must be
properly defined.
Billing Reads
- Daily schedules Billing Read parameters must be enabled.
- Daily schedules Billing Read Time of Day parameters must be
properly defined.
Meter Data Downloads
In addition to the setup discussed in the Database
section above, the following must be defined and performed in order for data
downloads to function on a given day.
- MREX must be enabled.
- Peak Billing Period Start Time of Day
and Peak Billing Period
End Time of Day must be properly defined.
- Meters must be enabled.
- Data recording must be enabled
on all meters.
- Monthly schedules must be enabled.
- Monthly schedules must have properly defined (see below) daily
schedule(s) assigned
for that day.
- Daily schedules must be enabled.
- Daily schedules Data Download parameters must be enabled.
- Daily schedules Data Download parameters must
be properly defined.
Billing Data Exports
To export billing data currently available in the database, without
scanning the archives, proceed as follows:
- Parameter Billing Archive Scanning
must be Disabled.
- Export File Directory
must be defined - the location specified here receives the exported file.
- Execute the Export Billing
Data command.
To export billing data currently available in the database, and scan the
archives for reading extrema and averages, proceed as follows:
- Archive the data by executing the
RUEX Archive
Data Recording Files.
- Make certain that the archives located in the RURDR
archive directory remain available for the duration of the billing data
export.
- Parameter Billing Archive Scanning
must be Enabled.
- Export File Directory
must be defined - the location specified here receives the exported file.
- Specify which meters are to be included in the export by defining the Export Meters
parameter.
- If above parameter is set to By Monthly Schedule, parameter Export Meters On Monthly Schedule
must specify the monthly schedule of interest.
- Parameter Billing Scan Start Date and Time
and Billing Scan End Date and Time
must be properly defined.
- Make certain that the value of Data Rec. Interval (Minutes - For Reports)
parameter matches that of Data Recording Interval (Minutes)
in RUEX. The latter must have been set before data recording was started
on all meters.
- If any bad data is to be filtered out, parameter Y Axis Filtering
must be Enabled, and parameters Y
Lowest and Y Highest must
be specified.
- Execute the Export Billing
Data command.
