(2) Transfers can be accomplished even in cases where there is an overlap between
the source and destination device.
In the case of transmission to the smaller device number, transmission is from (S);
for transmission to the larger device number, transmission is from (S)+ (n-1).
The points specified in n exceed those of the corresponding device specified in (S) or
(D), sequence program error occurs.
Safety observation warnings (SM24) are turned ON and error code (SD32): 10, detail
code (SD33): 8010H are stored.
