Service-orientated architectre for process controlsystems

摘要

A service-oriented architecture for process control systems is disclosed. In one example, a method for conveying process control information between a client process (204) and a server process (202) in a process control system (200) establishes a server process including a plurality of process control services (206, ., 210), each of which has a corresponding service interface (212, ., 216). The example method also establishes a client process having a proxy (220, ., 224) for each of the plurality of services to which the client process establishes a communicative connection. Additionally, the example method provides port information associated with the service interfaces to the client process to enable the conveyance of process control information between the client process and the server process.
