2.23.3.2 Transfer of Measured Values
Measured values can be transferred via the interfaces to a central control and storage unit.
The measuring range in which these values are transmitted depend on the protocol and, if necessary, additional
settings.
2.23.3.3 Information List
Protocol Transmittable measuring range, format
IEC 60870–5–103 0 to 240 % of the measured value.
IEC 61850 The primary operational measured values are transmitted.
The measured values as well as their unit format are set out in detail in manual PIXIT
7SJ.
The measured values are transmitted in „Float“ format. The transmitted measuring
range is not limited and corresponds to the operational measurement.
PROFIBUS,
Modbus, DNP 3.0
The unit format of the measured values on the device side is at first automatically gen-
erated by means of the selected nominal values of current and voltage within the system
data.
The current unit format can be determined in DIGSI or at the device via Menu Opera-
tional Values.
The user can select via DIGSI which operational measured values (primary, secondary
or percentage) must be transmitted.
The measured values are always transmitted as 16-bit values including sign (range ±
32768). The user can define the scaling of the operational measured value to be trans-
mitted. This will result in the respective transmittable measuring range.
For further details, please refer to the descriptions and protocol profiles.
