52 Process Image WAGO-I/O-SYSTEM 750750-494 3-Phase Power Measurement ModuleManualVersion 1.2.0Collections for harmonics analysis (020, 021, 022)The corresponding harmonics analysis collection is selected in the I/O moduleoutput data and the MET_IDs set. These measured values are then made availablein the input data.The type of measured value is selected in the harmonics analysis collections usingthe corresponding MET_ID_1. The following types of measured data areavailable:MET_ID_1 = 001 : RMS value current for fundamental component orharmonicMET_ID_1 = 002 : RMS value voltage for fundamental component orharmonicMET_ID_1 = 003 : THD (Total Harmonic Distortion) for fundamentalcomponent or HD (Harmonic Distortion) for currentharmonicMET_ID_1 = 004 : THD for fundamental component or HD forvoltage harmonicMET_ID_2, MET_ID_3 and MET_ID_4 are then used to select the harmonic(MET_ID_x = 1 ... 40) or fundamental component (MET_ID_x = 100) for themeasured values defined by MET_ID_1 are to be made available in the processimage input data. This means that 3 measured values are provided with the inputdata.Example 1:Byte Output data Input data0 0x00 0x481 0x03 (Status query) 0x002 0x00 0x403 0x14 (COL_ID) 0x14 (COL_ID_SEL)4 0x02 (MET_ID_1) 0x02 (MET_ID_1_SEL)5 0x64 (MET_ID_2) 0x64 (MET_ID_2_SEL)6 0x01 (MET_ID_3) 0x01 (MET_ID_3_SEL)7 0x02 (MET_ID_4) 0x02 (MET_ID_4_SEL)8 --- Measured value type Ueff - [7:0] = 0x029 --- Measured value type Ueff - [15:8] = 0x0010 --- Measured value type Ueff - [23:16] = 0x0011 --- Measured value type Ueff - [31:24] = 0x0012 --- Ueff – Fundamental component L1 [7:0]13 --- Ueff – Fundamental component L1 [15:8]14 --- Ueff – Fundamental component L1 [23:16]15 --- Ueff – Fundamental component L1 [31:24]16 --- Ueff – 1st harmonic L1 [7:0]
