Operand
Items
Description
1: Add mode
Writes additional data from the end of the file.
When no file exists, a new one is created.
2: Write position
specification mode 1
Writes data from the position after the number
of bytes stored in [S2+3] and [S2+4] from the
head of the file.
3: Write position
specification mode 2
Writes data from the position after the number
of bytes stored in [S2+3] and [S2+4] from the
end of the file.
D2+2
Options
-
D2+3
Writing position
(file pointer)
Number of bytes
from the
beginning or end
of the file
● This is effective when the write position specification mode is selected for
[D2+1].
● The setting of the writing position (file pointer) indicates the position in
bytes from the head of the stored file.
● In the case of writing position specification mode 1, when completing
writing to an SD memory card, the end position of the newly-saved data
counting from the head of the file is stored in the areas [D2+3] and [D2+4].
● In the case of writing position specification mode 2, when completing
writing to an SD memory card, the end position of the newly-saved data
counting from the end of the file is stored in the areas [D2+3] and [D2+4].
D2+4
D2+5
Number of written
data
Stores the number of data items that could be written after writing to the file.
Example 1: If the number of data items to be written is 40 and the file has 100
free spaces, 40 is stored for the number of written data.
Example 2: If the number of data items to be written is 40 and the file has 30
free spaces, 30 is stored for the number of written data.
Example 3: If the number of characters to be written is 40 and the file has free
space for 100 characters, 40 is stored for the number of characters written.
Example 4: If the number of characters to be written is 40 and the file has free
space for 30 characters, 30 is stored for the number of characters written.
