2 Instruction Descriptions
The following figure shows a programming example. If the write buffer def[] is BYTE data, 100 bytes of
data is written to the file.
LD
FileWrite_instance
A
Execute
abc FileID
def[0]
WriteBuf
UINT#100 Size
The FileWrite instruction writes the contents of the write buffer WriteBuf[] to the position
of the file position indicator in the file specified by FileID in the SD Memory Card. Then
the data size that is actually written is output to WriteSize.
WriteBuf[0] =def[0]
WriteBuf[1] =def[1]
: :
WriteBuf[99]=def[99]
Size UINT#100
Writing is performed for 100 elements.

One-hundred elements are written to the position of the file
position indicator. The def[] array is a BYTE array, so 100
bytes are written.
