8.6.13 Data set DS 91 statistical information
The table below shows the content of data set 91 in which the statistical information on the
SENTRON circuit breakers is transmitted. As with the other data sets, the property of each
data point is additionally transmitted in the property byte.
The table below contains the data sets DS91: Statistical information (length 84 bytes, read-
only):
