Loopback data length
Number of bytes of loopback data.
■Data communication in ASCII code
Convert the numerical value to 4-digit ASCII code (hexadecimal), and send it from the upper digits.
■Data communication in binary code
*1
Send 2-byte numerical values from lower byte (L: bits 0 to 7).
*1 For C24, the additional code may be added. (Page 35 Additional code (10H))
Ex.
For 5 bytes
ASCII code
0 0 0 5
30 30 30 35
H H H H
Loopback data
The following characters can be used.
• 0 to 9 (30H to 39H)
• A to F (41H to 46H)
Specify the loopback data in ASCII code while communicating in binary code.
Ex.
For 'ABCDEF'
ASCII code, binary code
