Flexible Process Image
An input data word in a flexible process image can read measured values from
any channel.
The flexible process image is enabled via WAGO-I/O-

on the „Phase L1“,
„Phase L2“ and „Phase L3“ tabs.
1st Example:
Reading out the current (rms value), voltage (rms value) and active power of
phase L2
Enter 0x10 (channel index 1, process data index 0) into control byte C0,
0x11 (channel index 1, process data index 1) into control byte C1 and
0x12 (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) and
the 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 and
the voltage (rms value) of phase L2
Enter 0x00 (channel index 0, process data index 0) into control byte C0,
0x01 (channel index 0, process data index 1) into control byte C1 and
0x11 (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) and
the voltage (rms value) of phase L2 is returned in input data word 3 (D4, D5).
