Internal Devices
This chapter describes internal devices.
The MICRO/I includes an internal HMI device to control HMI functions, and control device
*1
for control functions.
1.1 HMI Device Addresses
■ HMI Internal Relay (LM)
This is a bit-unit device.
■ HMI Keep Relay (LK)
This is a bit-unit device that holds the values of device. The value of this device can be set to 0 by clearing the project
data download option or online function, or it becomes 0 if the backup battery is drained. 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 Relay (LTC)
The HMI Timer is a bit-unit device that can be changed to 1 in value of device switched by the Timer from Parts. It
can store 32 addresses.
■ Digital Input (LEX), Digital Output (LEY)
Digital input/output relay for expansion module connected to HG4G/3G and HG2G-5F.
For details, refer to Chapter 30 “2.1 Using Digital I/O Modules” on page 30-12.
■ HMI Temporary Relay (LBM)
This is a bit-unit device for temporarily storing values. The value of this device switches between screens and text
groups and user accounts, and it becomes 0 if the screen is reset.
■ HMI Expansion Input (LI), HMI Expansion Output (LQ)
Input or output bit devices used with HG1P. For details, refer to Chapter 35 “Function Keys” on page 35-76. LIC to LID
and LQ0 to LQ1 are reserved areas.
*1 HG5G/4G/3G/2G-V only
*2 HG2J-7U only
*3 HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F/-5T, HG1G/1P only
*4 HG4G/3G, HG2G-5F only
*5 HG1P only

R/W is an abbreviation of Read/Write. R/W indicate that both reading and writing are possible, while R
indicates that only reading is possible.
