摘要： A system for integrating a wireless network with wired field devices includes a field unit that communicates with the wired field devices using a first wired field device protocol. A gateway wirelessly communicates with the field unit and communicates over a network using one or more second wired field device protocols. The gateway also converts between the first wired field device protocol and the one or more second wired field device protocols. The gateway could further permit access to the wired field devices by a component of the process control system (such as a process controller, asset management tool, or configuration tool) that does not support the first wired field device protocol. At least one of the field unit and the gateway could appear as a multiplexer or linking device to the component of the process control system, such as a HART multiplexer or a Foundation Fieldbus or Profibus linking device.

摘要： A gateway is used to segment a network, such as a Fault Tolerant Ethernet (FTE) network, into islands. The gateway receives traffic from a first island, forwards part of the traffic to a second island, and blocks another part of the traffic from being forwarded to the second island. The forwarded traffic could include unicast traffic. The blocked traffic could include broadcast or multicast traffic, including diagnostic messages from one or more nodes in the first island.

摘要： Various techniques are disclosed for improved reliability of wireless communications using packet combination-based error correction. For example, a method includes receiving a first message transmitted wirelessly, where the first message contains a first copy of a data packet and has at least one error. The method also includes receiving a second message transmitted wirelessly, where the second message contains a second copy of the data packet and has at least one error. The method further includes identifying a set of bit positions based on where the first and second copies of the data packet differ and modifying the set of bit positions to produce a modified set of bit positions. In addition, the method includes modifying one or more bit values in the modified set of bit positions to produce at least one modified copy of the data packet and determining if the at least one modified copy of the data packet is error-free.

摘要： An apparatus is provided for facilitating integration of a wireless field device (such as a wireless sensor or actuator) and a wired protocol that is used in a process control system. The apparatus supports a wireless field device protocol for communicating with the wireless field device. The apparatus also supports a wired field device protocol for communicating with other components of the process control system over a network. The apparatus could map a wireless application model associated with the wireless field device protocol to a wired application model associated with the wired field device protocol. The apparatus could actually support multiple mappings from the wireless application model to wired application models associated with multiple wired field device protocols. As particular examples, the wired field device protocol(s) could include the HART, Foundation Fieldbus, Profibus, and/or Modbus protocols. The network could represent an Ethernet network or a serial network.

摘要： An alarm recovery method and device for regenerating a list of alarm state values of a device after loss of communication or other discontinuity in processing is disclosed. The method and device are implemented in a control system for the control of a process. In normal operation the device sends notification messages on a high priority basis to a computer to update the alarm state values of a list. When communication is lost and then resumed, or other discontinuity of processing occurs and is restored, the recovery procedure begins by notifying the notification manager of the start of the notification process, saving alarm condition disable states, disabling each enabled alarm condition, allowing the device to generate return-to-normal notifications, restoring the original alarm condition disable states, allowing the device to generate appropriate current active alarm notifications, and notifying the notification manager of the end of the notification process. The notification manager reliably re-synchronizes the alarm states since the re-generated alarms are communicated at the same priority as the new alarm state changes, preventing mis-matches possible with other alarm state-access methods.
摘要翻译：公开了一种用于在通信丢失或处理中的其它不连续性之后再生设备的报警状态值列表的报警恢复方法和装置。该方法和装置在用于控制过程的控制系统中实现。在正常操作中，设备以高优先级的形式向计算机发送通知消息，以更新列表的报警状态值。当通信丢失然后恢复，或其他不连续处理发生并恢复时，恢复过程开始于通知通知管理器开始通知过程，保存报警条件禁用状态，禁用每个启用的报警条件，允许设备生成返回正常通知，恢复原始报警条件禁用状态，允许设备生成适当的当前活动警报通知，并通知通知管理器结束通知过程。通知管理器可靠地重新同步报警状态，因为重新生成的报警以与新的报警状态改变相同的优先级进行通信，从而防止与其他报警状态访问方法的误匹配。
