For details of data transmission and reception processing in a program for writing
output data sets in polling mode, refer to Section 8.2.3 (2).
Please replace the BUFSND and BUFRCV instructions with the SOCSND and
SOCRCV instructions.
The following table lists data to be sent at writing.

*1 Since the QJ71E71-100 treats application data in Little Endian format, the byte-order needs to be
swapped.
