s(IN) Input
ENO Output status (TRUE: Normal, FALSE: Abnormal)

Processing details
■Operation processing
• These functions convert the DINT type data input to (s) to REAL type data and output from (d).
(s)
16543521
DINT
• A value input to (s) is the DINT type data value.
• The number of significant figures of the REAL type data is approximately 7 since the data is processed in 32-bit single
precision.
• The converted data includes an error (rounding error) if an integer value is outside the range of -16777216 to 16777215.
■Operation result
1.
Function without EN/ENO
The operation processing is executed. The operation output value is output from (d).
2.
Function with EN/ENO
The following table lists the execution conditions and operation results.
Execution condition
EN
TRUE (Executes operation)
FALSE (Stops operation)
*1 When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is
not used.
Operation error
There is no operation error.
