摘要： There is described a method for transmitting synchronization messages in a communication network, the communication network comprising a plurality of network nodes communicating with one another, each containing an internal clock, which is timed with a node clock frequency assigned to the respective network node. The synchronization messages transmitted in the communication network serve to synchronize the times of the internal clocks of the network nodes and contain the pulse counter status of a synchronization clock operating at a predefined synchronization clock frequency. The pulse counter status is estimated by each network node and updated in the synchronization message. Changes in the synchronization clock frequency are taken into account when estimating the pulse counter status. Precise determination of the pulse counter status is achieved with the aid of an approximation of the change over time in the pulse ratio between synchronization clock frequency and node clock frequency by means of a function, with the result that the pulse ratio on transmission of a new synchronization message can be predicted and a precise current pulse counter status can be determined on the basis of the predicted pulse ratio. The method is particularly suitable for use in a communication network of an industrial automation system, whose components communicate with one another for example according to the Profinet standard.

摘要： A processing of consistent data sets by asynchronous application of a subscriber in an isochronous, cyclical communication system is provided. Accordingly, by connecting a communication memory and a consistency, transmission and reception buffer, copying processes leading delay can be kept to a minimum.

摘要： Upon reception of a message which is relevant to synchronization, the circuitry in a device forms a piece of reception-time information and this information is inserted into or appended to the received message and forwarded such that the reception-time information can be received by at least one synchronization application in the device. When a message is transmitted, the circuitry in the device forms a piece of transmission-time information, and this information is sent to at least one synchronization application initializing the message in the device. A fundamental advantage can be seen in that the economic outlay, particularly the outlay in terms of circuitry, for implementing the synchronization of the clocks and the determination of the communication-network or transmission-medium delay times, particularly on the basis of the IEEE standard 1588, m is substantially reduced.
摘要翻译：在接收到与同步相关的消息时，设备中的电路形成一段接收时间信息，并将该信息插入或附加到所接收的消息中，并转发，使得接收时间信息可以在设备中至少有一个同步应用程序。当发送消息时，设备中的电路形成一段传输时间信息，并将该信息发送到初始化设备中的消息的至少一个同步应用。可以看出，一个根本的优点在于，特别是基于IEEE标准，经济支出，特别是用于实现时钟同步和确定通信网络或传输介质延迟时间的电路方面的费用 1588，m大大减小。
