25.7 Converting WORD to BOOL
WORD_TO_BOOL(_E)
These functions convert a value from WORD data type to BOOL data type.
Setting data
■Description, type, data type
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.
• 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.
*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.
