(Process) (Redundant)
These functions convert a value from WORD data type to BOOL data type.

Argument Description
EN Execution condition (TRUE: Executed, FALSE: Not executed)
s (IN) Input
ENO Output status (TRUE: Normal, FALSE: Abnormal)
d Output
Processing details
■Operation processing
• These functions convert the value input to (s) from WORD data type to BOOL data type, and output the converted value
from (d).
• When the input value is 0H, FALSE is output.
• When the input value is other than 0H, TRUE is output.
(s)
0H
1567H
WORD
• Input a WORD 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.
Operation error
There is no operation error.
