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 system includes a plurality of wireless nodes including multiple controller nodes. Each controller node is configured to execute at least one of multiple control algorithms for controlling at least a portion of a process. Each control algorithm is associated with one or more sensor nodes and/or actuator nodes. At least one wireless node is configured to distribute the control algorithms amongst the controller nodes. At least one wireless node may be configured to redistribute the control algorithms amongst the controller nodes in response to one or more triggering events. A triggering event could include a new controller node being added to the system, and at least one wireless node could be configured to redistribute the control algorithms amongst the controller nodes including the new controller node. Redistribution of control algorithms can change a physical location where at least one control algorithm is executed without interrupting control of the process.

摘要： A wireless system gateway cache is presented. The gateway includes a first, wireless interface, a second interface, and a cache controller. The cache controller receives a characteristic of a parameter of a first device. The cache controller also receives a value of the parameter from the first device via the first interface and stores the value according to the characteristic of the parameter. The cache controller further receives a request for the value of the parameter from a second device via the second interface and sends the stored value to the second device in response to the request.

摘要： A caching method and system for a control system having a fast network and a slow network that each contain devices involved in the control of a process is disclosed. The cache is disposed in a gateway interface device interconnected with both the fast and the slow networks. The cache is populated only in response to requests of clients connected in the fast network but is refreshed independently of the fast network. To reduce traffic on the slow network, the cache is populated with a collection of parameters to which a requested parameter belongs. This avoids a round trip on the slow network for future requests of the requested parameter and other members of the collection. A parameter is removed from cache if an associated expiration timer expires before a further request therefor is received. Cache refresh is variable based on loading of the slow network and responsiveness of the devices of the slow network.
摘要翻译：公开了一种具有快速网络和慢速网络的控制系统的缓存方法和系统，每个控制系统都包含涉及过程控制的设备。缓存设置在与快速和慢速网络互连的网关接口设备中。缓存仅在响应于在快速网络中连接的客户端的请求而被填充，而是独立于快速网络刷新。为了减少慢速网络上的流量，缓存将填充一个请求的参数所属的参数集合。这避免了慢速网络上的往返行程，以便将来请求的参数和集合的其他成员的请求。如果相关联的到期定时器在接收到进一步的请求之前到期，则从缓存中删除参数。基于缓慢网络的加载和慢速网络的设备的响应性，缓存刷新是可变的。

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： A wireless network includes a leaf node, which generates a data message. The data message is routed through infrastructure nodes to a gateway infrastructure node, which is coupled to a wired network. A wireless interface module is also coupled to the wired network and communicates with the gateway infrastructure node. Multiple copies of the data message are created in the wireless network due to redundancy mechanisms supported in the wireless network, such as redundant connectivity and redundant message routing. The multiple copies of the data message are received at the gateway infrastructure node or the wireless interface module, which identifies the copies and communicates a single copy of the data message over the wired network to a destination. In this way, the redundancy mechanisms supported in the wireless network are concealed from wired components coupled to the wired network.
