用于过程网络的专用网络诊断模块
摘要：
一种可耦合到分布式过程控制网络的网络诊断模块，该分布式过程控制网络经由耦合到网络的多个现场设备控制工业过程，该网络诊断模块包括可耦合到该网络并且被配置为向该网络诊断模块提供从该网络接收到的能量的电源块、可耦合到该网络并且被配置为在该网络上双向通信的通信块、以及可耦合到该网络并且被配置为作出网络和该网络的协议参数的诊断测量的诊断块。该网络诊断模块本身不是检测或控制该工业过程的任意过程变量的现场设备，从而使该网络诊断模块能够基本上置于沿着该网络的任何位置以永久地监测该网络。
摘要（英）：

A network diagnostic module coupleable to a distributed process control network that controls an industrial process via field devices coupled to the network includes a power block coupleable to the network and configured to power the network diagnostic module with energy received from the network, a communications block coupleable to the network and configured to bi-directionally communicate over the network, and a diagnostics block coupleable to the network and configured to make diagnostic measurements of network and protocol parameters of the network. The network diagnostic module is not itself a field device that detects or controls any process variable of the industrial process, enabling the network diagnostic module to be placed essentially anywhere along the network to permanently monitor the network.
