Data To Be Specified In Command - Mitsubishi Electric MELSEC IQ-R series Reference Manual

Data to be specified in command

This section explains the contents and specification methods for data items which are set in each command related to the
user frame.
Frame No.
Specify the number of target user frame.
Type Setting value
Default registration frame 1H to 3E7H
User frame 3E8H to 4AFH
8001H to 801FH
■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 values from lower byte (L: bits 0 to 7).
Ex.
For 3E8H
ASCII code
0 3 E 8
30 33 45 38
H H H H
Number of registration data byte, number of frame byte
Specify the number of bytes of registration data.
Function Setting value
Data registration, 1H to 50H (1 to
read data 80)
Deletion 0H
For the number of registration data byte, calculate the variable data as 2 bytes.
For the number of frame byte, calculate the variable data as 1 byte.
For the variable data, refer to the following manuals.

■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 values from lower byte (L: bits 0 to 7).
Ex.
When the registration data is ETX + variable data (sum check code) + CR + LF
Number of registration data byte = 1-byte (ETX) + 2-byte (variable data) + 1-byte (CR) + 1-byte (LF) = 5
Number of frame byte = 1-byte (ETX) + 1-byte (variable data) + 1-byte (CR) + 1-byte (LF) = 4
