    • There is described an automation network, an access service proxy for an automation network and a method for transmitting operating data between a programmable controller and a remote computer, wherein the operating data of the programmable controller can be transmitted via the Internet or an intranet by means of the HTTP protocol and displayed and/or modified on the remote computer by an Internet browser. The access service proxy here contains a server for supplying the web pages containing the operating data of the programmable controller to the Internet browser of the remote computer, an interface, to which an engineering system can be connected so that operating data of the programmable controller can be transmitted using a communication mechanism for automation-engineering field communication via the connection between access service proxy and engineering system, and a synchronization unit for updating the content of the web pages if the operating data is modified by the engineering system. This provides uniform access to the operating data of the programmable controller and consequently data consistency and security against unauthorized access.
    • 描述了自动化网络,用于自动化网络的接入服务代理和用于在可编程控制器和远程计算机之间传送操作数据的方法,其中可编程控制器的操作数据可以经由因特网或内部网通过装置 的HTTP协议,并通过Internet浏览器在远程计算机上显示和/或修改。 这里的访问服务代理包括一个服务器,用于将包含可编程控制器的操作数据的网页提供给远程计算机的因特网浏览器,接口,工程系统可以连接到该接口,使得可编程控制器的操作数据可以 使用用于通过接入服务代理和工程系统之间的连接进行自动化工程现场通信的通信机制,以及如果工程系统修改了操作数据,则更新网页内容的同步单元。 这提供了对可编程控制器的操作数据的统一访问,并因此提供数据一致性和安全性以防止未经授权的访问。
