33-2 WindO/I-NV4 User’s Manual
â– HMI Special Relay (LSM)
A specific function is assigned for each of the 96 special internal relay (LSM0 to LSM95).
*1 HG5G/4G/3G/2G-V, HG4G/3G, HG2G-5F only
*2 HG2G-5T, HG1G/1P only
*3 This is applicable for models with an audio interface only.
Device Address
Function/Part
LSM0 Normally set to 1.
LSM1
When Base Screen is switched, a value of this bit is 1 only on the second scan.
It also operates when switching text group or user account, or resetting the display screen.
LSM2
When Base Screen is switched, a value of this bit is 1 only on the first scan.
It also operates when switching text group or user account, or resetting the display screen.
LSM3
When Base Screen is switched, the value of this bit is 0 only on the first scan.
It also operates when switching text group or user account, or resetting the display screen.
LSM4 Alternates between 0 and 1 with each scan.
LSM5 When Popup Screen is opened, a value of this bit is 1 only on the first scan.
LSM6 While touch panel is pressed, a value of this bit is 1.
LSM7
Alternates between 0 and 1 each time data is read (read scan) from all external device addresses being
used by External Device Communication 1.
LSM8
When the power is turned ON, then a value of this bit is 1. When switching to another screen from the
default screen or when switching text group or user account, then the value is 0.
LSM9
When value changes from 0 to 1, the backup data stored in flash memory is restored.
When it becomes 1 value does not become 0 until the Touch is reset or 0 is written.
LSM10
When switched from 0 to 1, the current backlight setting and the data for Keep Relays and Keep Register
configured in the Data Storage Area are transferred to the flash memory.
Once LSM10 switches to 1, it does not change to 0 until MICRO/I recycles power or 0 is written to LSM10.
LSM11
Changes from 0 to 1 when the Base Screen is switched, after the values of all external device addresses
being used are read, and remains 1 until there is a switch to another screen.
It also operates when switching text group or user account, or resetting the display screen.
LSM12 When Popup Screen is closed, a value of this bit is 1 only on the first scan.
LSM13
Value becomes 0 when Popup Screen is opened, and then changes from 0 to 1 after the values of all
external device addresses being used by that Popup Screen are read.
LSM14 to 17 Reserved
LSM18
When value changes from 0 to 1, access to USB flash drive is stopped. The access state can be checked
with the value of LSM19.
When it becomes 1 value does not become 0 until the MICRO/I is reset or 0 is written.
LSM19 Bit is 1 during USB flash access. When 0, the USB flash can be removed.
LSM20
*1
Access to the SD memory card stops when this bit is switched from 0 to 1. The access state can be
checked with the value of LSM21.
LSM21
*1
Bit is 1 during SD memory card access. When 0, the SD memory card can be removed.
LSM22
This is the Operation Log function. When data in excess of the amount that can be recorded in one
operation occurs, the value becomes 1.
When it becomes 1 value does not become 0 until the MICRO/I is reset or 0 is written.
LSM23
*1
This bit is 1 while copied.
LSM24
*1
This bit is 1 while writing the data to the SD memory card.
LSM25
*2
This bit is 1 while writing the data to the USB flash drive.
LSM26 Reserved
LSM27
*3
Stops playing the sound file when this bit is turned from 0 to 1.
LSM28 to 29 Reserved
LSM30
If a value of this bit is 0, all files (including the subfolders with files) under the source folder will be copied
to the destination folder. If the value is 1, only the files (excluding the subfolders with files) under the
source folder will be copied to the destination folder.
LSM31
If a value of this bit changes from 0 to 1, file copy process is terminated. If a value of this bit changes
from 0 to 1 while copying the files, MICRO/I will stop the file copy function after copying the current file.
If this value is 1, file copy function is not executed.
LSM32 Reserved
