TIME_TO_BOOL
This function converts a TIME variable to a BOOL variable.
If you omit an input or output parameter, a building error will occur.
This function converts TIME data In to BOOL data Out .
If the value of In is 0 ms (T#0ms), the value of Out is FALSE.
If the value of In is 1 ms (T#1ms) to 49 days 17 h 2 min 47 s 295 ms (T#49d17h2m47s295ms) (i.e., not
T#0ms), the value of Out is TRUE.
To convert BOOL data to TIME data, refer to BOOL_TO_TIME.
• 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.
