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 Energy Meter. 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) (Page 164) and section Measured value data record
for minimum values (DS 145) (Page 165).
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 12 bytes output
data, you can
● Reset the minimum and maximum values for
phases.
● Reset minimum and maximum values for each
phase.
If you use the module version with 2 bytes output data, you always reset all the minimum
and maximum values simultaneously.
