COMMUNICATION BETWEEN TWO CLIENTS VIA A SERVER

摘要

The invention relates to a method for communication between two clients (5, 14) via a server (1) in a network using OPC-UA. According to said method, a virtual server object (2) which provides a server (2) functionality to a first (5) of the two clients (5, 14) is implemented in the server (1) by making available to the first client (5): a virtual address space (7) in an address space (3) of the server (1), and a process for generating and modifying virtual server nodes (12) in said virtual address space (7). The server (1) allows the second client (14) to access virtual server nodes (12) in the virtual address space (7) and informs the first client (5) each time that the second client (14) accesses a virtual server node (12) in the virtual address space (7).
