28 Process Image WAGO-I/O-SYSTEM 750750-493 3-Phase Power Measurement ModuleManualVersion 1.2.04.3 Flexible Process ImageAn input data word in a flexible process image can read measured values fromany channel.The flexible process image is enabled via WAGO-I/O-CHECK on the „Phase L1“,„Phase L2“ and „Phase L3“ tabs.1st Example:Reading out the current (rms value), voltage (rms value) and active power ofphase L2Enter 0x10 (channel index 1, process data index 0) into control byte C0,0x11 (channel index 1, process data index 1) into control byte C1 and0x12 (channel index 1, process data index 2) into control byte C2.The current (rms value) of phase L2 is returned in input data word 1 (D0, D1),the voltage (rms value) of phase L2 is returned in input data word 2 (D2, D3) andthe active power of phase L2 is returned in input data word 3 (D4, D5).2nd Example:Reading out the current (rms value) and voltage (rms value) of phase L1 andthe voltage (rms value) of phase L2Enter 0x00 (channel index 0, process data index 0) into control byte C0,0x01 (channel index 0, process data index 1) into control byte C1 and0x11 (channel index 1, process data index 1) into control byte C2.The current (rms value) of phase L1 is returned in input data word 1 (D0, D1),the voltage (rms value) of phase L1 is returned in input data word 2 (D2, D3) andthe voltage (rms value) of phase L2 is returned in input data word 3 (D4, D5).
