3.1.1.1 Measured Values Mapping
The SICAM P 7KG7750/55 device supports transmission of measured values via the
communication protocol IEC 60870-5-103.
All measured values are transferred as per-unit values.
The column "100 % corresponds to" in the table below shows the relation between the
100 % per-unit value and the corresponding measured value. Additional explanations
are given below the table.
Please also refer to chapter 2.1.2 for the selection of the measured value ranges via
protocol.
