WriteEx([NewValue], [NewTimestamp], [NewQuality])

Allows changing the value, date and time, and quality of a Discrete Measurement Source in a single operation. This method returns a Boolean which indicates if the operation was successful or not. This method is only available for the PowerDiscreteOperatorSource object. The NewValue parameter specifies the new value of the Discrete Measurement Source. If omitted, the Discrete Measurement Source's value is not modified. The NewTimestamp parameter specifies a new date and time of the Discrete Measurement Source. If omitted, uses the date and time at the moment of this method's call. The NewQuality parameter specifies a new quality for the Discrete Measurement Source. If omitted, assumes a Good (192) quality.
