This function converts a TIME variable to a DWORD variable.
If you omit an input or output parameter, a building error will occur.
This function converts TIME data In to DWORD data Out.
Example When Value of In Is 49 days 17 h 2 min 47 s 295 ms (T#49d17h2m47s295ms)
• The value of Out will be DWORD#16#FFFFFFFF.
To convert DWORD data to TIME data, refer to DWORD_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.
