Harmonic Analysis Collections (020, 021, 022)

In the I/O module output data, the corresponding harmonic analysis collection is
selected and the MET_IDs are set. These measured values are then made
available in the input data.
The type of measured value is selected in the harmonic analysis collections using
the corresponding MET_ID_1. The following types of measured values are
available:
MET_ID_1 = 001:
MET_ID_1 = 002:
MET_ID_1 = 003:
component or harmonic distortion (HD) for current upper harmonic
MET_ID_1 = 004:
component or harmonic distortion (HD) for voltage upper harmonic
MET_ID_2, MET_ID_3 and MET_ID_4 are then used to select the upper
harmonic (MET_ID_x = 1 .. 40) or fundamental component (MET_ID_x = 100) for
the measured values defined by MET_ID_1 that are to be made available in the
process image input data. This means that 3 measured values are provided with
the input data.
