Setting data Description
(S) Data which will be converted into signed 16-bit integer value
Processing details
• The data specified with (S) is converted into a signed 16-bit integer value.
• The data range of (S) is -32768 to 32767.
• When (S) is a 64-bit floating-point type, its fractional portion is rounded down before conversion is made.
• If (S) is a 16-bit integer type, its value is returned unchanged, with no conversion processing performed.
Operation error
An operation error will occur if:
• The (S) data is outside the range -32768 to 32767.
• (S) is an indirectly specified device and its device No. is outside the range.
Program example
■Program which converts the data of D0L into a signed 16-bit integer value and substitutes the
result to #0
#0 = SHORT(D0L)
#0 K-30000
