    • A system for transferring a signal between a field device and a control system component includes a field linking unit (104, 110) and a system gateway (118, 120). The field linking unit (104, 110) is electrically coupled to a field device (102A-102C, 108A-108C), and a signal is transferred between the two using a first protocol. The system gateway (118, 120) is electrically connected to a control system component, and the signal is transferred between the two using a second protocol. The field linking unit (104, 110) and the system gateway (118, 120) communicate wirelessly. One of the field linking unit (104, 110) and the system gateway (118, 120) may encrypt the signal before sending, and the other may decrypt the signal upon receipt. The system may also include at least one intermediate node (114, 116), and the field linking unit (104, 110) and the system gateway (118, 120) may communicate wirelessly via the intermediate node(s) (114, 116).
    • 用于在现场设备和控制系统组件之间传送信号的系统包括场连接单元(104,110)和系统网关(118,120)。 场连接单元(104,110)电耦合到现场设备(102A-102C,108A-108C),并且使用第一协议在两者之间传送信号。 系统网关(118,120)电连接到控制系统组件,并且使用第二协议在两者之间传送信号。 场链接单元(104,110)和系统网关(118,120)以无线方式进行通信。 场连接单元(104,110)和系统网关(118,120)中的一个可以在发送之前对信号进行加密,另一个可以在接收时对信号进行解密。 系统还可以包括至少一个中间节点(114,116),并且场链接单元(104,110)和系统网关(118,120)可以经由中间节点(114,116)无线地通信, 。

    • A system for integrating a wireless network with wired field devices (101a-101m) includes a field unit (102a-102n) that communicates with the wired field devices (101a-101m) using a first wired field device protocol. A gateway (106a-106b) wirelessly communicates with the field unit (102a-102n) and communicates over a network (118) using one or more second wired field device protocols. The gateway (106a-106b) converts between the first wired field device protocol and the one or more second wired field device protocols. The gateway (106a-106b) is adapted to further permit access to the wired field devices (lOla-lOlm) by a component of the process control system (100), such as a process controller (104), asset management tool (122), or configuration tool (124), that does not support the first wired field device protocol. At least one of the field unit (102a-102n) and the gateway (106a-106b) is adapted to appear as a multiplexer or linking device to the component of the process control system (100), such as a HART multiplexer or a Foundation Fieldbus or Profibus linking device.
    • 用于将无线网络与有线现场设备(101a-101m)集成的系统包括使用第一有线现场设备协议与有线现场设备(101a-101m)进行通信的现场单元(102a-102n)。 网关(106a-106b)与现场单元(102a-102n)无线通信,并使用一个或多个第二有线现场设备协议通过网络(118)进行通信。 网关(106a-106b)在第一有线现场设备协议和一个或多个第二有线现场设备协议之间进行转换。 网关(106a-106b)适于进一步允许由过程控制系统(100)的组件(例如过程控制器(104))资产管理工具(122)访问有线现场设备(101a-101b) 或配置工具(124),其不支持第一有线现场设备协议。 现场单元(102a-102n)和网关(106a-106b)中的至少一个适于作为多路复用器或链接设备显示到过程控制系统(100)的组件,例如HART多路复用器或基础 现场总线或Profibus链接设备。
