Chapter 9 Expansion Module 226
※ When the preset value in “Analog Output Set” screen is a constant, this value will be stored in DR register,
(DRD4~DRD7) and the AQ value equals to (DRx/4.095). For example, CH1 is configured as mode 1, set a
constant value, 4000, then the value of AQ01 will be 977, and HMI displays 9.77V.
※ Once the preset value refers to other variable, its value is also stored in DR register, (DRD4~DRD7), but it will
be equal to AQx * 4.095. (DRx=AQx*4.095).
