2.1 HMI Device Addresses
■ HMI Data Register (LDR)
8,192 points are available.
■ HMI Keep Register (LKR)
The value in these registers is retained during power OFF.
The maximum number of HMI Keep Register depends upon the number set in WindO/I-NV3. For details, refer to
Chapter 16 “Minimum and Maximum Amount of Data Storage and Number of Addresses” on page 16-2.
■ HMI Temporary Register (LBR)
This register value will be cleared to 0 when a text group or user account is changed, when a screen is reset or the
screen is changed. 128 points are available.
■ HMI Timer (Current value) (LTD)
HMI Timer stores the current value of Timer from the parts. 32 points are available.
■ HMI Special Data Register (LSD)
The HMI Special
Data Registers (256 points) perform the following special operations.
