    摘要： A receiver network component operates in a communication network of an automation system. The component receives data messages sent redundantly by transmitter network components of the communication network and rejects duplicates of an already received data message. Interoperability of network components from different manufacturers is ensured even for device-redundant transmitter network components and redundant transmission of data messages is achieve with comparatively low complexity. The receiver network component is prompted by reception of a current data message from one of the transmitter network devices to check whether a data message with identical useful data has already been received from another transmitter network component. The data message is processed if it is received for the first time and it is rejected as a duplicate if it is a data message with such useful data that have already been received in an earlier data message from another transmitter network component.

    摘要翻译： 接收机网络组件在自动化系统的通信网络中操作。 组件接收由通信网络的发射机网络组件冗余发送的数据消息，并且拒绝已经接收的数据消息的重复。 即使对于设备冗余的发射机网络组件，也能确保来自不同制造商的网络组件的互操作性，并且以相对低的复杂度实现数据消息的冗余传输。 通过从发射机网络设备之一接收当前数据消息来提示接收机网络组件，以检查是否已经从另一发射机网络组件接收到具有相同有用数据的数据消息。 如果数据消息是第一次接收到的，则处理数据消息，并且如果它是具有已经在来自另一发射机网络组件的较早数据消息中接收到的有用数据的数据消息，则该数据消息被重复。

    摘要： A method determines a propagation time of a message in a communication network. The message is transmitted from a first network component to a second network component along a communication connection, and the first network component detects a transmission time of the message and stores the corresponding transmission time information. The propagation time is determined using the transmission time information. The aim is to improve the accuracy when determining the propagation time. This is achieved in that the second network component returns the message to the first network component immediately after the message is encountered in the second network component. The first network component detects a reception time upon receiving the returned message and stores corresponding reception time information of the message. The propagation time of the message along the communication connection is determined using the transmission time information of the message and the reception time information of the message.
