    摘要： The present invention relates to a system and methodology providing a virtual “namespace” architecture between client and server components in an industrial automation environment, wherein the namespace can be a structured store of logical names, instances and definitions, together with access and modification components. An Active Directory Service Interface (ADSI) family can be employed, for example, to navigate and access the namespace structure and contents. The present invention employs the concept of a “service” to encapsulate server-side behavior accessed through the namespace. Thus, logical names can be utilized to decouple client components from the physical location and implementation of server components. Some services, known as “basic services”, may ignore the logical container structure exposed by an area model in a namespace. By contrast, services which utilize an area context and a set of named service items to interact with clients can be referred to as “namespace extensions.” Further, services known as “context services” may use the area model to scope and control accesses, yet not employ a service item namespace organized by the area model.

    摘要： The present invention relates to a system and methodology providing automation services in a distributed industrial controller environment. In one aspect of the present invention, a data access service is provided that includes, sending and receiving data to and from a data access service namespace operative in the distributed controller environment. In another aspect of the present invention, an alarming service is provided wherein data values are monitored in a server component according to predetermined conditions configured by a user or other entity. If the data values are determined to be outside of boundaries as defined by the predetermined conditions, an alarm can be communicated to a plurality of other components cooperating in the distributed environment.
