9410 series Logging
Waveform record memory calculations
The meter can simultaneously capture waveforms triggered by events on all channels
to a maximum of 96 cycles for each waveform record.
The memory required is calculated as follows:
Memory consumption for each waveform (in Bytes) = [2 x number of samples per cycle
+ 12] x [number of cycles in waveform x 2] + 32.
A single waveform record requires approximately 8 kB of memory.
See the ION Setup online help, available from www.usa.siemens.com/pds, for more
information about the logging memory allocations and other meter logging memory
information displayed by the ION Setup Assistant.
Data logging overview
Your meter has data logging capabilities, including a special type of data log which is
an event log, which logs prioritized events.
Data logs are recorded by your meter and stored in the meter’s memory inside
configurable data logs. Your meter’s data logs are retained if the meter loses power.
Logged data can be used by energy management software. Logs can be configured to
either overwrite the oldest data when full (circular), or to stop writing data to the log
when the number of logged records reaches the maximum log depth (stop-when-full).
Your meter ships with a comprehensive data-logging configuration consisting of data
logs set up to record values at specific intervals or on conditions. Your meter’s default
data logging configuration should be sufficient for most applications, but you can also
reconfigure existing logs or create new logs for custom applications if needed.
Your meter can also be configured to email data log information.
NOTE: Adding or deleting data logs or their parameters outside of the ION Setup
Assistant should only be undertaken by those with an advanced understanding of ION
architecture and their meter’s template.
See the Internal email client feature technical note, available from
www.usa.siemens.com/pds, for instructions on how to configure your meter to email
logged data.
See the ION Reference , available from www.usa.siemens.com/pds, for more
information about ION architecture and ION modules.
Default data logging configuration
Your meter is equipped with preconfigured data logs which you can modify.
The default data logging configuration might be used by other components of your
power monitoring system. 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 and the data they use and on your meter’s memory.
Revenue log
The Revenue Log is configured for use with UTS MV-90 billing software. The default
values logged by the Revenue Log are as follows:
