Processing details
■Operation processing
• These functions convert the value input to (s) from DWORD data type to INT data type, and output the converted value
from (d).
• The upper 16-bit data of the input value (DWORD data type) are discarded. (Refer to (1) in the figure below.)

(1)
• Input a DWORD data type value to (s).
■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.
