Devices
■ HG Timer Relay (LTC)
The HG Timer (single-bit I/O point) is a relay switched on by a part timer.
The Display Timer can use 32 points.
■ HG Expansion Input (LPX), HG Expansion Output (LPY)
With the HG2F/3F/4F these are expansion module input and output relays installed at the back. You can use 16-point
(bit device) or 1-point (word device) expansion input and expansion output.
With the HG2S these are input and output relays that are used with models that have L6 series square-type switches on
the upper switch block. You can use 8-point (bit device) or 1-point (word device) expansion input and expansion output.
■ HG Input (LX), HG Output (LY)
These are the HG2S input and output relays.
With a bit device 4 external input points and 3 external output points can be used, and with a word device 1 point of
external input and output can be used.
■ HG Digital Input (LEX), HG Digital Output (LEY)
Digital input/output relay for expansion module connected to HG2G-5F, HG3G/4G.
For details, refer to Chapter 29 “2.1 Using Digital I/O Units” on page 29-3.
■ HG Data Register (LDR)
The HG Data Register is an internal MICRO/I register. 8192 points are available.
■ HG Keep Register (LKR)
The HG Keep Registers are internal MICRO/I registers. The value in these registers is retained during power OFF. The
maximum number of HG Keep Register depends upon the number set in WindO/I-NV2. For details, refer to Chapter
16 “Minimum and Maximum Amount of Data Storage and Number of Addresses” on page 16-2.
■ HG Temporary Register (LBR)
HG temporary 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.
■ HG Timer (Current) (LTD)
Timer registers store the current value of a Timer. 32 points are available.
■ HG Link Register (LLR)
An area that stores device address data for the registered PLC 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.
■ HG Special Registers (LSD)
The Special Registers (256 points) perform the following special operations.
Refer to Chapter 34 “MICRO/I Specifications” on page 34-1 for the correspondence between the push-
button switches and the expansion I/O.

LSD14 Stores current time data from MICRO/I. “Month” (2 BCD digits)
LSD15 Stores current time data from MICRO/I. “Day” (2 BCD digits)
LSD16 Stores current time data from MICRO/I. “Hour” (2 BCD digits)
