RTD data nominal values
The nominal values are rounded to the nearest integer (for example 2.5 = 3),
according to the RTD input signal type and the range parameters mentioned in the
Technical Reference Manual .
If a linearization curve is used for the 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 9.5.-4 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.

Available measurements depend on the configuration (for example
phase voltage or phase-to-phase voltage).
