2.3.3 Load profile
The consumption values for active energy import (kWh) and active energy export (kWh) are
stored in the device at 15-minute intervals, where they are retained for a period of
24 months.
After this period has elapsed, the oldest value is overwritten by the newest value. If storage in
conformance with PTB-A 50.7 is to be upheld, it is absolutely essential that the device clock is
able to synchronize the time regularly via an SNTP server within its power reserve.
In addition to the 15-minute values, the PAC2200CLP stores daily, monthly and annual
consumption of active energy for import and export over 10 years.
Each value is stored along with additional information about its validity and is marked as
invalid if at least one of the following flags is set:
→ FLAG_QUALITY_TIME_UNSECURE (time uncertain, e.g. time changed by more than 9
seconds or power reserve expired)
→ FLAG_QUALITY_UNSECURE (current and/or voltage out of range)
→ FLAG_MULTIPLE_TIMECHANGE (time changed several times, or changes ≥ 1 s)
→ FLAG_CURRENT_TRANSFORMER (current transformer setting changed)
→ FLAG_LOGBOOK_FULL (calibration logbook is full)
The stored load profile can be viewed locally on the display or via the web server. It is also
possible to download it in CSV format.
