End Code; Error Code - Mitsubishi Electric MELSEC IQ-R series Reference Manual

Setting method
■Data communication in ASCII code
Convert the numerical value to 2-digit ASCII code (hexadecimal), and send it from the upper digits.
■Data communication in binary code
The same as the data communication in ASCII code, use the numerical value converted to the 2 digit ASCII code
(hexadecimal).
Send 2-byte numerical value from the upper byte (H: bits 8 to 15).
Ex.
Sum check code: '05' (ASCII code 30H, 35H)
ASCII code, binary code

Setting method
■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
Send 2-byte numerical value from the lower byte (L: bits 0 to 7).
Ex.
When error code 7151H is returned
