    Abstract: A wireless communication device providing a node in an industrial wireless network investigates if there is more than one data packet with process control data from the same data originating device destined for a process control device in a transmission queue, where the data originating device is an interface to the process being controlled and transmits data packets in the transmission queue. If there is more than one such data packet, the wireless communication device further compares time stamps of the data packets, where a time stamp reflects the time of generation of a corresponding data packet, keeps the newest data packet and discards older data packets, so that only the most recent data packets from a data originating device are sent to the process control device from the node.

    Abstract translation: 在工业无线网络中提供节点的无线通信设备研究是否存在多于一个的数据分组,该数据分组具有来自发往传送队列中的过程控制设备的相同数据始发设备的过程控制数据,其中数据发起设备是接口 到正被控制的进程并且传输传输队列中的数据分组。 如果存在多于一个这样的数据分组,则无线通信装置进一步比较数据分组的时间戳,其中时间戳反映相应的数据分组的生成时间,保持最新的数据分组并丢弃较旧的数据分组,因此 来自数据发起设备的仅最近的数据分组从该节点发送到过程控制设备。
