delay is the time interval in milliseconds for the break. The actual period of the break can be longer than this time interval.
error code is the error or warning code. If error code is nonzero, an error occurred. You can wire error code to one of the error handler VIs, which describe the error and give you options on how to proceed when an error occurs.
