receiving a request for data from an OPC UA Client;
determining by a hardware implemented control circuit of the OPC UA Server whether at least one of the request or the data requires a slow data access or a fast data access as in comparison to each other;
when the determination indicates that at least one of the request or the data requires the slow data access, obtaining first data from a first address space of a memory unit of the OPC UA Server;
