2.1 HMI Device Addresses
■ HMI Data Register (LDR)
8192 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-NV4. For details, refer to Chapter 16 “Minimum and Maximum Amount of Data Storage
and Number of Addresses” on page 16-2.
■ HMI Timer Current Value (LTD)
This register stores the current value of Timer from the parts. 32 points are available.
■ Digital Input (Word) (WLEX), Digital Output Word (WLEY)
These registers handle the relays for digital inputs (words) and digital outputs (words) of expansion modules
connected to the HG4G/3G and HG2G-5F in word units. For details, refer to Chapter 30 “2.1 Using Digital I/O
Modules” on page 30-12.
■ HMI Temporary Register (LBR)
This register can be used to store value as temporary. 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 Link Register (LLR)
An area that stores the data of the registered device addresses for the external device during Sub Host
Communication.
64 points are available.
This register can also be used as an internal register like LDR when Sub Host Communication is not used.
■ HMI Expansion Input (Word) (WLI), HMI Expansion Output (Word) (WLQ)
These registers handle the expansion input or the expansion output used with HG1P in word unit. WLQ is
a reserved area.
