    • In aspects, the present invention discloses a method for communicating with a plurality of field devices using a remote terminal unit. The plurality of field devices includes a first set of field devices and a second set of field devices capable of communicating using a first and second wireless communication protocols respectively. The method comprises scanning for a beacon message from a first field device, determining a corresponding wireless communication protocol associated from the first field device, identifying a first set of configuration blocks for communicating with the first field device based on a configuration schema file and the corresponding wireless communication protocol of the first field device, and building a protocol stack for use with a radio front end from the one or more radio front ends using the first set of configuration blocks, for communicating with the first field device from the plurality of field devices.

    • A networking system is discussed. The system may be used for industrial networks where access to field device data is valuable. Commands, such as read or write requests to particular field device data, may be encapsulated within messages conforming to an object-oriented protocol, such as, for example, Common Industrial Protocol (CIP). Responses to the commands may also be encapsulated within CIP messages. The encapsulated commands and responses may be transmitted between various devices of an industrial network, including a controller and a gateway device, such as a multiplexer, of the industrial network. Encapsulating the commands and responses may provide a tunneling mechanism allowing a controller complete access to the data of the field devices in communication with the gateway device.
    • 讨论了一个网络系统。 该系统可用于对现场设备数据访问有价值的工业网络。 诸如对于特定现场设备数据的读取或写入请求的命令可以被封装在符合面向对象协议(例如,通用工业协议(CIP))的消息内。 对命令的响应也可以封装在CIP消息中。 封装的命令和响应可以在工业网络的各种设备之间传输,包括工业网络的控制器和网关设备,例如多路复用器。 封装命令和响应可以提供隧道机制,允许控制器完全访问与网关设备通信的现场设备的数据。
