摘要： A communication technique enables the efficient transmission of data through a low bandwidth and/or time delayed communication link and minimizes the idle time of the communication link by using a deferred acknowledgment of message bundles to temporally pack the communication link. The transmitting system stores messages to be transmitted in a pending message queue and applies a dynamic window to the pending message queue to define a message bundle to be sent through the slow communication link. The transmitting system requests an acknowledgment for at least one message within the bundle, but does not require an acknowledgment for every message within the bundle. Transmitted messages are temporarily stored as outstanding messages in a retransmission queue until the transmitted messages are acknowledged or until a time-out period associated with the messages has lapsed. When the transmitting station receives a timely acknowledgment in response to a requested acknowledgment, the transmitting station removes all outstanding messages associated with that acknowledgment from the retransmission queue.
摘要翻译：通信技术能够通过低带宽和/或时间延迟的通信链路有效地传输数据，并且通过使用消息束的延迟确认来最小化通信链路的空闲时间，以暂时包装通信链路。发送系统存储要在待定消息队列中发送的消息，并将动态窗口应用于待定消息队列，以定义要通过慢速通信链路发送的消息包。发送系统向捆绑中的至少一个消息请求确认，但不需要对捆绑内的每个消息进行确认。传输的消息作为未完成的消息临时存储在重传队列中，直到发送的消息被确认或直到与消息相关联的超时周期已经失效。当发送站响应于所请求的确认接收到及时确认时，发送站从重发队列中删除与该确认相关联的所有未完成的消息。

摘要： A method and system of communicating between a wireless network and a process control system communicatively coupled to a server via a process control system interface, such as OPC or a proprietary API. The wireless network may be a mesh network and the server may be a mesh server. The server receives data from the wireless network, where the data is generated from an input/output data point within the wireless network. The server maps the data between the input/output data point and a data point placeholder within the process control system. The server writes the mapped data to the corresponding data point placeholder of the process control system via the process control interface, and the mapped data is provided to the process control system as process control data native to the process control system. Process control data may also be provided to the server, mapped between a data point placeholder of the process control system and an input/output data point of the wireless network, and the mapped process control data is written to the corresponding input/output data point.

摘要： A process control system coordinates with an associated asset management system to implement a plant safety mechanism and, in particular, to prevent unintended changes to, or otherwise undesired operation of, one or more process control equipment resources in a process plant. A maintenance technician uses the asset management system to request access to one or more of the process control equipment resources. A process operator receives the request via the process control system and grants or denies the request. Process control equipment resources for which a process operator grants a request are inoperable, in part or in whole, by the process control system. Upon completion of the maintenance task, the maintenance technician requests to return control of the process control equipment resource to the process operator. The return is complete when the process operator acknowledges the return of the resource to the process control system.

摘要： A wireless communication system for use in a process environment uses mesh and possibly a combination of mesh and point-to-point communications to produce a wireless communication network that can be easily set up, configured, changed and monitored, thereby making a wireless communication network that is less expensive, and more robust and reliable. The wireless communication system allows virtual communication paths to be established and used within the process control system in a manner that is independent of the manner in which the wireless signals are sent between different wireless transmitting and receiving devices within the process plant. Still further, communication analysis tools are provided to enable a user or operator to view the operation of the wireless communication network to thereby analyze the ongoing operation of the wireless communications within the wireless communication network.
