Setting data
■Usable Data
: Usable
■Description, data type of result
Processing details
• The data specified with (S) is converted into an unsigned 32-bit integer value.
• The data range of (S) is 0 to 4294967295.
• When (S) is a 64-bit floating-point type, its fractional portion is rounded down before conversion is made.
• If (S) is a 32-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 0 to 4294967295.
• (S) is an indirectly specified device and its device No. is outside the range.
Program example
■Program which converts the data of D0 into an unsigned 32-bit integer value and substitutes
the result to #0L
