
The WS0-GETH automatically sends input data sets. The send data are stored to
the BUFRCV instruction receive data areas (D900 to D976) (refer to 1) in Figure
61). (The BUFRCV instruction is executed automatically upon data reception.)
 The byte order of the receive data
*1
is changed, and input data sets are stored to
the corresponding input data set storage areas (W0 to W4D) (refer to 2) in Figure
61).
*1 Since the QJ71E71-100 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.
