■
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.
■
