8.6.8 Data set DS 72 min. and max. measured values
The table below shows the content of data set 72 in which the minimum and maximum
measured values of the currents are transmitted. It also contains the associated time stamps
for these minimum and maximum measured values.
The table below contains the data sets DS72: Min./max. measured values of the currents
and the associated time stamps (length 236 bytes, read-only):
