用于将无线数据合并到已建过程控制系统中的设备及方法
摘要：
本发明公开了在无线网络和通过诸如OPC和专有API的过程控制系统接口通信连接到服务器的过程控制系统之间进行通信的方法及系统。无线网络可以是网格网络，服务器可以是网格服务器。服务器接收来自无线网络的数据，该数据是从无线网络中的输入/输出数据点产生的。服务器在输入/输出数据点和过程控制系统中数据点位置标志符之间映射数据。服务器通过过程控制接口将映射数据写到过程控制系统的对应数据点位置标志符，而所映射的数据被提供给过程控制系统，作为源自过程控制系统的过程控制数据。过程控制数据也可以被提供给服务器，在过程控制系统的数据点位置标志符和无线网络的输入/输出数据点之间映射，并且所映射的过程控制数据被写到对应的输入/输出数据点。
摘要（英）：

A method and system of communicating between a wireless network and a process control system communicatively coupled to a server via a process control system interface, such as OPC or a proprietary API. The wireless network may be a mesh network and the server may be a mesh server. The server receives data from the wireless network, where the data is generated from an input/output data point within the wireless network. The server maps the data between the input/output data point and a data point placeholder within the process control system. The server writes the mapped data to the corresponding data point placeholder of the process control system via the process control interface, and the mapped data is provided to the process control system as process control data native to the process control system. Process control data may also be provided to the server, mapped between a data point placeholder of the process control system and an input/output data point of the wireless network, and the mapped process control data is written to the corresponding input/output data point.
