WORD_TO_BOOL
This function converts a WORD variable to a BOOL variable.
If you omit an input or output parameter, a building error will occur.
This function converts WORD data
In
to BOOL data
Out
.
If the value of
In
is WORD#16#0000, the value of
Out
is FALSE.
If the value of
In
is WORD#16#0001 to WORD#16#FFFF (i.e., not WORD#16#0000), the value of
Out
is TRUE.
To convert BOOL data to WORD data, refer to BOOL_TO_WORD.
• The input condition depends on whether the output is safety data or standard data. If the condition is
not met, a building error will occur.
• If you set a safety data type variable for the output terminal, set a safety data type variable for the
input terminal as well.
• If you set a standard data type variable for the output terminal, you can set either a safety data type
variable or a standard data type variable for the input terminal.
• If the input value is not WORD#0 or WORD#1, a cast error will occur and the program will stop.
