Descriptions for the Process Image

The I/O module provides a large number of measured values for a 3-phase
power supply system. These measured values are organized into collections
which can be selected by specifying the COL_ID. The following collections are
available:
COL_ID = 010 – AC measured values
All measured values provided by the I/O module during AC measurement.
COL_ID = 020 – Harmonic analysis, L1
All measured values provided by the I/O module during the harmonic analysis for
phase L1.
COL_ID = 021 – Harmonic analysis, L2
All measured values provided by the I/O module during the harmonic analysis for
phase L2.
COL_ID = 022 – Harmonic analysis, L3
All measured values provided by the I/O module during the harmonic analysis for
phase L3.
The individual measured values are identified within a collection by specifying a
MET_ID. The following section "Measured Value Collections" contains a
definition of all the measured value collections with the corresponding MET_IDs,
measured value data types and scaling factors in the process image.
Example 1:
Measured value:
Data type in the PI:
PI scaling factor (1A version):
PI scaling factor (5A version):
PI scaling factor (Rogowski version):
Example 2:
Measured value:
Data type in the PI:
PI scaling factor (all versions):
The I/O module measured values are made available in the process image as a
function of the selected collection (COL_ID) and of the selected measured values
(MET_ID) of this collection.
