all the external devices being used by that Popup Screen are read.
LSM14
When the indirect value of an indirect device positioned on the Base Screen changes, value becomes
1, and reading of the indirect device starts. When reading is complete value becomes 0.
LSM15

and reading of the indirect device starts. When reading is complete value becomes 0.
LSM16 to 17

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 Touch is reset or 0 is written.
LSM19

Address Function/Part
• Since the HMI Special Internal Relay can be written to, even if a write is attempted, the contents will not
change.
• Transfer of the LSM10 Keep Relay and Keep Register to the flash memory can take an excess of one second.
Writing to the flash memory can be repeated a maximum of 100,000 times. Keep writing to the flash memory
to a minimum. LSM10 cannot be used while the ladder program is running. LSM10 does not work while the
ladder program or FBD program is running.
• When there is no remaining battery power, data transferred with LSM10 will be restored once the power to
the Touch has been turned on.
The period of processing for all of the parts set on the displayed screen is called a scan of the Touch. It is
not related to the period of reading the value of external devices.
