Caution
Note that "n2" words are shifted every time the drive input turns from OFF to ON in the WSFLP instruction, but that
"n2" words are shifted in each operation cycle in the WSFL instruction.
"n2" words are shifted in each operation cycle in the WSFL instruction.
Error
If the transfer source
is equivalent to the shifted device
, an operation error occurs (error code: K6710).
