Data set DS 94 current measured values
The table below shows data set 94 in which all current measured values are transmitted. The
additional property bytes provide information on the availability and correctness of the
measured values.
The table below contains the data sets DS94 (up to byte 140; part 2 follows): Current
measured values (length 197 bytes, read-only):
