Remarks
Calling on primitive types, a call of this method will return the primitive value. On complex types (structures and arrays) it depends on the ISymbolLoader settings what will happen. In non dynamic modes: the raw byte Array will be returned, in dynamic mode: A Value will be created on the fly. A negative timeout indicates that the Default Timeout for the communication will be used. 0 means timeout is switched off.
