■
Start from 0 in Always Entry Mode of Numerical Input
*1
Select this check box to display 0 when a Numerical Input that has the Always Entry Mode check box selected on
the General tab is displayed on the screen. When this check box is cleared, the value of device is displayed.
This option is reflected for all Numerical Inputs configured in the project.
■
Storage Method of String Data
*1
Selects the handling method for text entered with the Character Input and values of devices read by the Message Display.
■
Storage Method of 32-bit Numerical Data
*1
Selects the handling method for the values of devices when BIN32(+) , BIN32(+/-) , BCD8 , or float32 is selected
for Data Type from the following.
This setting only applies to word devices. When the bit devices in control devices are handled as words, this setting is
always from Lower word .
*1 Advanced mode only
*2 Color LCD models only
*3 Monochrome LCD models only
from Upper byte: The values of devices are read from and written to the upper byte.
Example: When the text ABCDE is entered with the Character Input and written to the
destination device LDR100
from Lower byte: The values of devices are read from and written to the lower byte.
Example: When the text ABCDE is entered with the Character Input and written to the
destination device LDR100

NULL terminating character
When handling strings, 0 is written to the device as the NULL terminating character and treated as the end
of the string.
from Upper word (Excludes bit devices handled as words):
Values of the word device are read from and written to the upper word.
Example: When
Data Type for the Numerical Input is BIN32(+) and the numerical value
12345678 (hex) was entered and written to destination device LDR100
from Lower word: For word devices and bit devices handled as words, values of devices are read from and
written to the lower word.
Example: When
Data Type for the Numerical Input is BIN32(+) and the numerical value
12345678 (hex) was entered and written to destination device LDR100
