(4) Program example
Just like the WRITE instruction program example, this program example is for writing
data of D750 to D753 of station No.0 (own station) into W300 to W303 of station No.18
(target station) when M112 is turned on.
Furthermore, when the write notification device (D3) of the target station is turned on,
the data of W300 to W303 are stored in D500 to D503.

By devices
Completion status indication device ((D2)+1) is turned on and an error code is
stored in Completion status ((S1)+1) of the control data.
According to the error code, check the error details and take a corrective action.
(Refer to Section 12.5.)
REMARK
Compared to the WRITE instruction program example, the SWRITE instruction
program example has a different section where the write notification device (D3) is
specified at the end of the arguments. (Refer to Section 10.6 (4).)
