INT_TO_BOOL
This function converts an INT variable to a BOOL variable.
If you omit an input or output parameter, a building error will occur.
This function converts INT data In to BOOL data Out .
If the value of In is INT#0, the value of Out is FALSE.
If the value of In is INT#
−
32768 to INT#
−
1 or INT#1 to INT#32767 (i.e., not INT#0), the value of Out is
TRUE.
To convert BOOL data to INT data, refer to BOOL_TO_INT.
• 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 INT#-32768 to INT#32767, a cast error will occur and the program will stop.
