0x00E0 Unsigned long 2 registers
Reading out the profile data memory (load profile, daily profile, monthly profile, annual
profile)
Each of the profile data memories contains 2 measuring channels:
•
Measuring channel 1: Active energy or active power import
• Measuring channel 2: Active energy or active power export
A special feature of the load profile memory (demand period duration of 15 minutes) is that
these channels are also available as
•
Arithmetic average power demand values (W)
• Cumulated average power demand values (W) and/or as
• Energy portions (Wh)
Each of these values can be converted to any of the others using the demand period duration
and the real measurement duration which is also available.
Any entry in the profile data memory can be marked as a data variable ("information flag
bytes") by the device. This information helps the user to identify occurrences during the
demand periods.
Description of the "information flag bytes":
FLAG_TARIFF_T1 0x00xxxxxx
FLAG_TARIFF_T2 0x01xxxxxx
FLAG_TARIFF_UNKNOWN 0xFFxxxxxx
FLAG_QUALITY_UNSECURE 0x00800000
FLAG_QUALITY_AUXPOWER_FAIL 0x00400000
FLAG_QUALITY_PERIOD_TO_SHORT 0x00010000
FLAG_QUALITY_TIME_UNSECURE 0x00200000
FLAG_MULTIPLE_TIMECHANGE 0x00040000
FLAG_CURRENT_TRANSFORMER 0x00080000
FLAG_LOGENTRY 0x00001000
FLAG_LOGBOOK_FULL 0x00002000
FLAG_Q1 0x00000040
FLAG_BAD_QUALITY_MARKER 0x00000001
Reading out the logbook (event memory)
In a similar way to profile data records, event data records can be read out using "data log
identifier" (0x01), "data identifier" (0x00) and "advanced data identifier" (OID and number of
data records).
