Mitsubishi Electric MELSEC iQ-R Series User Manual page 319

• 'Send frame number designation' (Un\G186 to 285/346 to 445) Write the user frame No. to be sent in the order in
which they are output from the position designated in the output start pointer designation area.
When transmitting data that is written in the send area, use 8000H as a temporary user frame No.
By designating user frame No. 8000H, C24 transmits the data in the send data specification area for the data quantity
designated in the send data quantity designation area.

Specifies the following user frame No. for the data to be sent.
Note that the number on the right side of the user frame No. below is the number used for transmission
without ASCII-BIN
conversion for only the data of any frame portion when transmission data is converted into ASCII-binary data
and transmitted.
0H: No transmission designation. (No additional transmission is allowed.)
1H to 3E7H/4001H to 43E7H: Transmits the default frame having the designated number.
3E8H to 4AFH/43E8H to 44AFH: Transmits the user frame having the designated number. (For flash ROM registration)
8000H/C000H: Transmits data in the transmission area of the buffer memory.
8001H to 801FH/C001H to C01FH: Transmits the user frame having the designated number. (For buffer memory registration)
The following transmission can be performed by adding 4000H to the registered user frame number and
specifying it.
• When ASCII-BIN conversion is enabled, a specified frame can be sent without the conversion. (Page
348 ASCII-BIN Conversion for Data Communicated with Nonprocedural Protocol)
• A specified frame can be transmitted without adding the additional code by the transparent code for sending
specification. (Page 328 Handling Transparent and Additional Codes for Nonprocedural Protocol Data
