Property Value

The default value of this property is Unknown (SparkplugDataType.Unknown).

Exceptions
ExceptionDescription

An invalid enumeration value was used.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Remarks

The default value of this property, SparkplugDataType.Unknown, has a special behavior that allows for dynamic changes of the actual data type. It is recommended that you always set the DataType to a specific data type other than SparkplugDataType.Unknown, for Sparkplug conformance, interoperability and better validation and error detection.
