Description
Data type of result
(S)
Word device/constant/calculation expression to be
substituted
(D)
Word device which will store the operation result
Data type of (D)
[Functions]
(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.)
(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.)
[Errors]
(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
• (D) or (S) is an indirectly specified device and its device No. is outside the
range.
