A method for transmitting real time data packets in a cyclic communication system, each transmission cycle having a first partial cycle (IRT-Z) for a real time communication portion and a second partial cycle (NRT-Z) for a non-real-time communication portion. The method includes determination () of a cycle number and processing of a transmission sequence of real time data packets in the first partial cycle. The transmission sequence is composed of one or more partial sequences (1, 2, 3, 4, 5), and the composition depends on the cycle number.

Method for transmitting real-time data messages in a cyclic communications system

The invention relates to a method for synchronizing a communications cycle and a communications node in a network. The node is formed with devices for receiving a desired value for a time base of a communications cycle of the communications node in a communications link to an additional communications node of the network. The node also includes devices for determining a system deviation between the desired value and an actual value of the time base, and a device for generating a manipulated variable for correcting the time base in accordance with the system deviation.

Communications system and method for synchronizing a communications cycle

A method for receiving data messages in communications systems having redundant network paths. Received data of a peripheral representation or image is routed to a node along at least two different network paths. This makes it possible to store a consistent peripheral representation or image in a memory () of a node, if there is a disturbance in the data transmission along one network path.

System and associated method for receiving data telegrams in communication systems having redundant network paths

The invention relates to a method for synchronizing nodes of a communication system comprising the following steps: receipt of a first synchronization message by a first node, whereby the first synchronization message contains a desired receipt time by a first node; correction of a time base of the first node, based on a deviation between an actual receipt time, determined as a result of the base time, and the desired receipt time.
