values
Note
Depending on the device composition not all of the indicated analog
inputs (and corresponding PROFIBUS-DP message positions) may be
available in the SIPROTEC device.
The given scaling values for the measured values in the standard
mappings apply to installations with the following nominal operating
values:
Nominal operating voltage of primary equipment (parameter address 1101):
è
1.0 ... 10 (32) kV
Nominal operating current of primary equipment (parameter address 1102):
è
10 ... 1000 A

Note
Changes of the scaling of the measured values are possible in
adaptation to the concrete installation enviroment. You find information
about this in the manual "7SJ61...63, 7SJ65, 6MD63, 7UM61
