2.1 HMI Device Addresses
■ HMI Data Register (LDR)
This register is an internal register of MICRO/I.
■ 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.
■ HMI Link Register (LLR)
An area that stores the data of the registered device addresses for the external device during when HG5G/4G/3G/2G-
V, HG4G/3G, HG2G-5F/5T, or HG1G/1p make 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.
