For details of data reception processing in a program for receiving input data sets
in auto update mode, refer to Section 8.2.4 (2).
Replace the BUFSND and BUFRCV instructions with the SOCSND and
SOCRCV instructions.
Since the Built-in Ethernet port QCPU treats application data in Little Endian
format, the byte-order needs to be swapped. Note that the byte order of the input
data set 1 and output data set 1 does not need to be changed because these
data are one byte long.
<Data need to be swapped>

Command and parameters (word data (16 bits))

Input data sets 2 and 3 (double-word data (32 bits))
(3) Monitoring data with a programming tool
The read input data sets can be monitored using the device monitor function of a
programming tool. For the execution results of the program for auto update
mode, refer to Section 8.2.2 (3).
