10.2
Resetting minimum and maximum values
Description
At the beginning of a new work order, it may be useful to reset the minimum and maximum
values of the AI Energy Meter HF. Resetting means that the minimum and maximum values
are reset to their initial values. Initial values are described, see section Measured value data
record for maximum values (DS 144) version 1 (Page 237), Measured value data record for
minimum values (DS 145) version 1 (Page 243), Measured value data record for maximum
values with time stamp (DS 154) (Page 239) and Measured value data record for minimum
values with time stamp (DS 155) (Page 245).
Minimum and maximum values are only reset using a Reset via output data (DQ bit).
Due to the differing lengths of the output data resetting of the minimum and maximum values
depends on the configured module version. If you use module versions with 20 bytes of
output data, you can:
● Reset the minimum and maximum values for
all
phases.
● Reset minimum and maximum values for each
individual
phase.
If you use the module version with 2 bytes of output data, you always reset
all
the minimum
and maximum values simultaneously.
Time stamps are set to initial values (01.01.1970, 0:00) on reset.
