Mitsubishi Electric MELSEC iQ-R Series User Manual page 351

At the time of data transmission with the user frame, it is possible to transmit data without converting the data in any user
frame portion or send area on the buffer memory even if "Convert" is designated in the ASCII-BIN conversion designation
area.
When sending data without ASCII-BIN conversion, specify the user frame number by the method shown below.
• Specify the number obtained by adding 4000H to the registered user frame No.
b15 b14 b13 to
Number of frames
0: Conversion enabled 1: Conversion disabled
0: Frame registered in Flash ROM 1: Frame registered in buffer memory
When sending data in the portions designated in 4001H to 44AFH, C000H to C01FH, the data is transmitted without
conversion even when the following designations are enabled.
• Specifying an additional code by the transparent code for sending specification (Page 326 TRANSPARENT CODES
AND ADDITIONAL CODES)
• Designating "Auto delete enabled" in the NULL character automatic removal designation area (Page 408 NULL
Character Removal to Send Data using Nonprocedural Protocol)

Processing order for data transmission/reception
The processing steps taken by C24 to transmit/receive data with ASCII-BIN conversion and transparent code designation
enabled are explained in the section for transparent codes and additional codes. ( Page 328 Handling Transparent and
