Word shift right
WSFR(P)
*1 Do not set a negative value in the number of word points (n2) to be shifted to the right.
Processing details
• Shifts (n1) words starting from (D) (n2) words to the right. After the shift, the function transfers (n2)-word data from (S) to
the (n2) words from ((D)+(n1))-(n2).
• QnUDVCPU, LCPU: The serial number (first five digits) is "16112" or later.
(S): Start number of the word device to be stored in shift data after shift to the right (BIN 16 bits)
(D): Start number of word device to shift to the right (BIN 16 bits)
n1: Word data length of shift data (n2
(D): Start number of word device to shift to the right (BIN 16 bits)
n1: Word data length of shift data (n2
n1 512) (BIN 16 bits)
n2: Number of word points to shift to the right (n2
n1 512)
(BIN 16 bits)
