RTD data nominal values
Nominal values are according to the RTD input signal type and the range parameters
mentioned in the Technical Reference Manual rounded to the nearest integer (e.g.
2.5 = 3).
If linearization curve is used for RTD input, the nominal value of this channel is the
absolute maximum value for this curve. A store and reset is needed after adjusting
the RTD input signal type and range parameters, if new nominal values are wanted
in IEC_103
Function blocks and available measurements
Table 9.7.-2 shows which function blocks produce measurement data mapped to the
IEC_103
class 2 measurement frames. This is how the relay configuration is
expected to be implemented. However, if signal types connected to a function block
do not match the following table, corresponding locations in the class 2 frame will
also be replaced by the actual signal types connected to the function block.
COLTC Tap changer position is transmitted as Class 1 data. Message type
identification 4, float format.
Available measurements depend on the configuration (e.g. phase voltage
or phase-to-phase voltage).
Example
If set No 11 is used, the ASDU octets will look like in the following figure:
