    • Embodiments of the invention are directed towards providing safe updating of objects in a computerized object-based system for process and manufacturing control. Some methods in some embodiments of methods may include providing a production environment within the system comprising operative versions of computer objects and at least one related engineering environment isolated from the production environment. Some embodiments of such methods may also include importing versions of objects to the engineering environment from a related environment, allowing a group of system-modifying users to modify the imported objects for creating modified versions of these objects and barring other users from modifying the imported objects, and exporting objects from the engineering environment to a related environment, where the exporting involves replacing current versions of objects in the related environment with modified versions for making the modified versions current versions.
    • 本发明的实施例旨在提供用于过程和制造控制的计算机化的基于对象的系统中的对象的安全更新。 方法的一些实施例中的一些方法可以包括提供系统内的生产环境,包括计算机对象的操作版本和与生产环境隔离的至少一个相关工程环境。 这些方法的一些实施例还可以包括从相关环境向对工程环境导入对象的版本,允许一组系统修改用户修改导入的对象以创建这些对象的修改版本,并禁止其他用户修改导入的对象 ,并将对象从工程环境导出到相关环境中,其中导出涉及使用修改版本替换相关环境中的对象的当前版本,以使修改版本成为当前版本。

    • A method and system for a client application (1) to request a data item from an access server (3) in a computer controlled control system. The control system includes objects and a plurality of access servers, which said objects represent various entities that have a defined functional meaning in the control system. Each access server, such as an OPC server, may provide access to one or more real-time data, historical data, and alarm and event data items. In an embodiment the method provides means, which enables the Access Service Handler (2) component, by querying a said object, to obtain a reference for a desired data item, to find out which access server handles the said data item. The Access Service handler then makes request to the identified access server.
    • 一种用于客户端应用(1)从计算机控制的控制系统中的访问服务器(3)请求数据项的方法和系统。 控制系统包括对象和多个访问服务器,所述对象表示在控制系统中具有定义的功能意义的各种实体。 诸如OPC服务器的每个访问服务器可以提供对一个或多个实时数据,历史数据以及警报和事件数据项的访问。 在一个实施例中,该方法提供了通过查询所述对象来获得访问服务处理程序(2)组件以获得所需数据项的引用的装置,以找出哪个访问服务器处理所述数据项。 然后,Access Service处理程序向所识别的访问服务器发出请求。
