Explanation of data table
The data table for transmission starts at the data register specified in S.
Use an F0 (MV) or F95 (ASC) instruction to write the data to be transmitted to the transmission data
-
storage area specified in S.
Operation when sending data
When the execution condition of the F159 (MTRN) instruction turns on and the "transmission done" flag
R9039 is on, operation is as follows:
1. [N] is preset in [S]. The "reception done" flag R9038 is turned off, and the reception data number is
cleared to zero.
2. The set data is transmitted in order from the lower-order byte in S+1 of the table.
During transmission, the "transmission done" flag R9039 turns off.
-
If system register No.413 is set to header (start code) with STX, the header is automatically added to
-
the beginning of the data.
The terminator (end code) specified in system register 413 is automatically added to the end of the data.
-
3. When all of the specified quantity of data has been transmitted, the S value is cleared to zero and the
"transmission done" flag R9039 turns on.
When you do not wish to add the terminator (end code) during transmissions:
Specify the number of bytes to be transmitted using a negative number.
-
If you also do not wish to add a terminator to received data, set system register 413 to "Terminator -
-
None".
Programming example:
The following program transmits 8 bytes of data without adding the terminator.
Key Point:
Do not include the terminator (end code) in the transmission data. The terminator is added
-
automatically.
When "STX exist" is specified for the header (start code) in system register 413, do not add the header
-
to the transmission data. The header is added automatically.
