Exceptions
ExceptionDescription

A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.

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.

The component is not licensed for the operation requested.
Remarks
The "Get" operation obtains value of an OPC property and stores it into the mapping source. Only mappings of type DAClientPropertyMapping are affected; other mappings are ignored.
Requirements
