Abstract
A method for communication between two clients via a server in a network using OPC Unified Architecture (OPC-UA), wherein a virtual server object that provides a server functionality to a first of two clients is implemented in the server by making available to the first client a virtual address space in an address space of the server, and a process for generating and modifying virtual server nodes in said virtual address space. The server allows the second client to access virtual server nodes in the virtual address space and informs the first client each time that the second client accesses a virtual server node in the virtual address space.
