A system () for industrial automation, including a field device () with a function unit (), in particular an actuator unit, sensor unit and/or control unit, which is configured to provide a function in accordance with a received payload (ND), and a communication unit () for receiving a payload signal (DS) containing the payload (ND) via a cable (), the communication unit () being configured to provide a parameter set (PS) on the basis of the payload signal (DS) and to carry out signal processing of the payload signal (DS) using the parameter set (PS) in order to obtain the payload (ND) from the payload signal (DS), the system () further comprising a diagnosis device () which is configured to determine a cable wear condition of the cable () in accordance with an indicator variable (IG) based on the parameter set (PS).

System and method for determining a cable wear status

A communication unit (S, S) for industrial automation for use in a communication system () of series-connected communication units (M, S, S). The communication unit includes a first input (E), a first output (A), and an internal clock generator (TG) which is adapted to provide an internal clock signal as system clock for clocking the communication unit (S, S), and wherein the communication unit (S, S) is configured to receive, via the input (E), a serial input data stream with payload data. The communication unit (S, S) has a timer (ZG) for providing a time value, the timer (ZG) being adapted to provide the time value based on an input symbol clock included in the input data stream.

Communication unit, control apparatus, communication system and method

A communication participant for an automation system, with a communication component that includes at least two identically formed communication interfaces, wherein each of the communication interfaces includes a receiving module for receiving incoming communication signals and a transmitting module for transmitting communication signals, wherein each of the at least two communication interfaces is designed for a communication with a directly adjacently arranged, plug-in connected communication participant and for a communication with a remotely arranged, cable-connected communication participant.

Communication participant and communication system

A communication unit (S, S) for industrial automation for use in a communication system () of series-connected communication units (M, S, S). The communication unit includes a first input (E) and a first output (A) and being configured to receive, via the input (E), an input serial data stream having payload data and to output, via the output (A), an output serial data stream (ADS) having payload data. The communication unit (S, S) is configured to determine clock information (TI) on the basis of an internal reference clock signal of the communication unit (S, S) and an input symbol clock of the input data stream and, using the clock information (TI), to provide the output data stream (ADS) with an output symbol clock whose clock rate is equal to the clock rate of the input symbol clock.
