DWDT Digital to Analog

	digital waveform is the waveform you want to convert to analog waveform.
	full-scale range (pk-pk) specifies the total peak-to-peak range, or the difference between the minimum and maximum, for the digital waveform or digital data. For example, if the maximum range of a waveform is 1 and the minimum is –1, the full-scale range for the waveform is 2. The default is 2.
	error in describes error conditions that occur before this node runs. With the following exception, this input provides standard error in functionality. If an error occurred before this node runs, this node outputs an empty waveform.
	data format specifies which binary representation you want to use for the digital waveform or digital data. 0 unsigned binary—Converts the data to unsigned binary. 1 offset binary (default)—The largest negative full-scale value is represented by all zeros, and the largest positive full-scale value is represented by all ones. Zero-scale is represented by a one (MSB) followed by all zeros, for example, binary 1000. 2 2's complement—Uses two's complement format, which is a common format for representing signed binary values. This format is similar to offset binary, but the MSB is inverted.
	analog waveform returns the waveform resulting from the conversion of digital waveform or digital table.
	resolution (out) returns the number of bits represented in the digital waveform or digital data.
	full-scale range (out) returns the total peak-to-peak range for the digital waveform or digital data.
	error out contains error information. This output provides standard error out functionality.
