Logging
Logging overview
The meter’s logging frameworks include factory-configured data recorders, waveform recorders,
and event logs.
The logging frameworks store data related to:
•
Power quality and compliance
•
Energy and demand
•
Revenue metering
•
Trending and forecasting
•
Meter events
When your system’s nominal parameters are programmed into the meter, power quality events
such as sags, swells and transients are automatically detected, and associated voltage and
current data and waveforms are logged. Meter data is stored in non-volatile memory, so data is
retained even if the meter loses power. If your system nominal values fluctuate, you can configure
the meter’s setpoint learning feature to learn your power system’s normal operating values, then
use that information to help identify voltage sags and swells.
The meter’s logging framework also supports burst data logging for sag/swell events. When burst
data logging is enabled, additional data records immediately before and immediately after the
sag/swell event are captured. Energy management systems can then retrieve this information for
use in applications, such as power event analysis.
TIP: Connect devices directly to an Ethernet network to help maximize the performance of your
power management system.
You can also configure the meter to email data from the logging frameworks. For more
information, see the Internal Email Client Feature technical note, available on
www.usa.siemens.com/pds.
Meter events are recorded in the meter’s onboard event log. You can also configure the meter to
record events to an external syslog server.
For details on how to set up syslog, see "Configuring Syslog network settings using ION Setup"
on page 231.
Default data logging configuration
The meter’s default template includes factory-configured data logs (Data Recorder modules).
These data logs and their configuration are used by other components of your power monitoring
system.
NOTE: Do not change the default configuration of any of the logs unless you understand the
impact of the change on these power monitoring system components, the data they use, and
your meter’s memory.
