Processing details
■Operation processing
• These functions convert the value input to (s) from REAL data type to DINT data type, and output the converted value from
(d).
(s)
16543521.0
REAL
• Input a REAL data type value to (s) within the range of -2147483648 to 2147483647.
• After conversion, the first digit after the decimal point of the input value (REAL data type) is rounded off.
■Operation result
1.
Function without EN/ENO
The operation processing is performed. The operation result is output from (d).
2.
Function with EN/ENO
The execution conditions and operation results will be as follows.
Execution condition
EN
TRUE (executed)
FALSE (not executed)
*1 If the value FALSE is output from ENO, the output data from (d) will be undefined. Create a program so that the undefined value will not
be used in operations.
