Abstract: A system for communicating data packets in a process control environment is described. A client device connects, via the network, to an historian device, creates, via a first dictionary manager module, a first tag dictionary, synchronizes, via the network, the first tag dictionary with a second tag dictionary created by the historian device, optimizes a packet via a packet optimization layer comprising scanning a tag ID present in the packet, determines a matching tag handle for the tag ID from the first tag dictionary, replaces each instance of the tag ID in the packet with the matching tag handle, and sends the optimized packet to the historian device via the network. The historian device connects, via the network, to the client device, creates, via a second dictionary manager module, the second tag dictionary, synchronizes, via the network, the second tag dictionary with the first tag dictionary created by the client device, receives the optimized packet from the client device via the network, converts the optimized packet back to its original form comprising scanning a tag handle present in the packet, determines a matching tag ID for the tag handle from the second tag dictionary, and replaces each instance of the tag handle in the packet with the matching tag ID.

Abstract: A system for historizing process control data. A configurator module registers a data source device with a historian server and indicates to the historian server to generate data source registration information for identifying the registered data source device. The historian server generates and stores the data source registration information. The historian server also generates a connection token comprising the data source registration information. The configurator module forwards the connection token to the data source device, which stores the token and sends it to the historian server with data. The historian server compares the connection token received from the data source device to the connection token stored by the historian server, wherein if they match, the historian server stores the data from data source device.

Abstract translation: 用于历史化过程控制数据的系统。 配置器模块将数据源设备与历史服务器进行注册，并向历史服务器指示生成用于识别注册的数据源设备的数据源注册信息。 历史数据库服务器生成并存储数据源注册信息。 历史数据服务器还生成包括数据源注册信息的连接令牌。 配置器模块将连接令牌转发到数据源设备，数据源设备存储令牌，并使用数据将其发送到历史数据服务器。 历史数据库服务器将从数据源设备接收到的连接令牌与由历史服务器存储的连接令牌进行比较，其中如果匹配，则历史数据服务器将存储来自数据源设备的数据。
