(S)
(D) Word device which will store the operation result
(1) The data value specified with (S) is substituted to the specified word device at (D).
(2) When (S) and (D) differ in data type, the data at (S) is converted into the data type
of (D) and the resultant data is substituted.
(When (D) is a 16- or 32-bit integer type and (S) is a 64-bit floating-point type, the
fraction part of (S) is discarded.)
(1) An operation error will occur if:
• The data at (S) is outside the data type range of (D); or
• (D) or (S) is an indirectly specified device and its device No. is outside the
range.
(1) Program which substitutes the D0 value to #0
#0 = D0
