First of all you should read this book to get a basic understanding of OPC UA:

Second, from your unprecise questions it is hard to guess what your problem is or what you are trying to do. However, I assume you are trying to connect the Twincat OPC UA Server with the UaDemoServer running on a different machine. As you might have found out yourself these are both UA Servers and hence can not be connected directly. Now another assumption is that you try to use the newly defined PLCopen function blocks. Therefore you must use the "client-side" of the Twincat UA product. This can only be done by calling special function blocks inside the PLC code (IEC61131-3). To do so you must have the latest Twincat version (or at least a version that supports UA-client-side) and you must read the Twincat documentation for details.
