Time (hour, minute, second)
Represent the hour, minute, second with 16-bit value.
• Hour: The binary value is represented with bits 11 to 15.
• Minute: The binary value is represented with bits 5 to 10.
• Second: The binary value divided by 2 is represented with bits 0 to 4.
When 20:50:58
File size
This indicates the file capacity in byte units.
Setting method
■Data communication in ASCII code
Convert the numerical value to 8-digit ASCII code (hexadecimal), and send it from the upper digits.
■Data communication in binary code
Send 4-byte numerical values
*1
from the lower byte (L: bits 0 to 7).
*1 For C24, the additional code may be added. (Page 35 Additional code (10H))
The file size is 7168 bytes
