D000030110 d – E650 Series 3 (ZMD400AT/CT, ZFD400AT/CT) – User Manual
A non-volatile memory (FLASH memory) contains the data of:

the stored value profile

the load profile 1

the load profile 2 (optional)

the event log

the three groups of dedicated event logs
The flash memory stores data without data loss in case of voltage failures.
No battery is required for this purpose.
The total size of the available memory for the stored billing value profile, the
load profile(s), the event log and the dedicated event logs is 1.8 MB.
At the end of the billing period, the meter stores the current value of the
registers to the stored value profile. Which energy registers and/or demand
registers are stored to the stored billing value profile can be selected by
parameterisation.
The stored value profile is organised as a circular buffer, i.e. the oldest
entry will be overwritten by the most recent entry. The memory capacity
which is available for the stored value profile depends on parameterisation.
The load profiles are used to save the values of various registers at regular
intervals. The measured values that are captured in the load profile can be
selected by parameterisation.
Load profile 2 is optional
The second load profile is optional and can be activated by
parameterisation.
The first load profile is generally used for billing purposes. Its capture
period has a range of 1...60 min. This load profile may also contain
instantaneous values and detailed status information for data processing in
central stations.
The second load profile can be used to store instantaneous values over a
period which differs from the period of the first load profile. Apart from the
differing capture period, the second load profile is identical with the first
load profile.
The load profile is organised as a circular buffer, i.e. the oldest entry will be
overwritten by the most recent entry. The memory capacity which is
available for the load profile(s) depends on parameterisation. If both load
profiles are activated, they share the memory capacity which is allocated to
the load profile(s).
