  • System uses time pulse that simultaneously transmits with time of day message to synchronize network user stations
    Patent number: 6854019
    Abstract: A network user system and a method of using the same in which one network user station (2c) is connected with another network user station (2a) via a message line (9a) and to which, in a receive mode, the other network user station (2a) can transmit a time message (Un, 5) comprising a time of day. The network user station (2a) also simultaneously transmits along with the time message a plurality of time pulses to the other network user stations (2b, 2d , 2e. . . ) in the system. The network user stations (2a, 2b, 2c, . . . ) record the time difference between the instant when the time pulses Tp are received and the instant when the time message (5) is received, and thereupon adjust the time of day contained in the time message (5) based on the time difference. This ensures that the time of day that is further processed in the receiver (4a, 4b, 4c. . .

  • NETWORK SUBSCRIBER STATION HAVING A FEATURE THAT PREVENTS INACCURACIES IN TIME MESSAGES
    Publication number: 20020126582
    Abstract: A network user station (2), which in a transmitting mode transmits telegrams (5) to another network user station (2) and in a receiving mode receives telegrams (5) from another network user station. Said telegrams contain messages of identical message length in a message string. One of said messages is a time message (5d) provided with a time of day. The network user station is provided with means (11; 13) for substantially preventing inaccuracies with respect to a transmittal and/or processing instant of the time of day.

  • Network subscriber station having a feature that prevents inaccuracies in time messages
    Patent number: 6449220
    Abstract: A network user station (2), which in a transmitting mode transmits telegrams (5) to another network user station (2) and in a receiving mode receives telegrams (5) from another network user station. Said telegrams contain messages of identical message length in a message string. One of said messages is a time message (5d) provided with a time of day. The network user station is provided with means (11; 13) for substantially preventing inaccuracies with respect to a transmittal and/or processing instant of the time of day.

  • Network subscriber for improved time synchronization accuracy and associated method therefor
    Publication number: 20020018402
    Abstract: A network subscriber (2c) is provided with a clock (8) and is connected to a further network subscriber (2a) via a network (1). In a receiving mode, the further network subscriber (2a) supplies a time message (5, Un) containing a time of day to the network subscriber (2c). The network subscriber (2c) includes a synchronization assembly in the form of an adjustment unit (10) that permits improved synchronization accuracy of the time of day. If a deviation between the time of the day included in the time message (5, Un) and a further time of the day indicated by the clock (8) is smaller than a predefined limit value, the synchronization assembly synchronizes the clock (8) with the time of the day that is included in the time message (5, Un) supplied by the further network subscriber (2a).

  • Synchronized network user system and method
    Publication number: 20020000919
    Abstract: A network user system and a method of using the same in which one network user station (2c) is connected with another network user station (2a) via a message line (9a) and to which, in a receive mode, the other network user station (2a) can transmit a time message (Un, 5) comprising a time of day. The network user station (2a) also simultaneously transmits along with the time message a plurality of time pulses to the other network user stations (2b, 2d, 2e . . . ) in the system. The network user stations (2a, 2b, 2c, . . . ) record the time difference between the instant when the time pulses Tp are received and the instant when the time message (5) is received, and thereupon adjust the time of day contained in the time message (5) based on the time difference. This ensures that the time of day that is further processed in the receiver (4a, 4b, 4c . . .
