    • obtaining (110), by an enabler component (11) of the end device (1), the message (4) from a control application (12) of the end device (1);
    • mapping (120), by the enabler component (11), based at least in part on the content of the message (4), and/or on a path through which the message (4) is delivered to the enabler component (11), the message to at least one functionality (3*) for time-sensitive communication that is to be used when transporting the message (4) over the Ethernet network (3);
    • converting (130), by the enabler component (11), the message (4) into one or more Ethernet frames (5);
    • encoding (140), by the enabler component (11), in at least one of said one or more Ethernet frames (5), a request (3**) to transport the message (4) according to at least one functionality (3*) for time-sensitive communication;
    • transmitting (150), by the enabler component (11), the one or more Ethernet frames (5) onto the Ethernet network (3);
    • decoding (160), by at least one network device (31) of the Ethernet network (3), the request (3**); and
    • forwarding (170), by the at least one network device (31), the message on the Ethernet network (3) according to the requested functionality (3*) for time-sensitive communication.

    摘要: The present invention provides a method for time synchronizing one or more devices in a control network using a first device. The method comprises selecting a first device from information of the topology of the control network. The method further comprises sending a first set of packets to the second device, receiving a first set of delay requests in response to the first set of packets, and sending a first set of delay responses in response to the first set of delay requests. The method further comprises, determining a first set of forward times and first set of backward times. The method further comprises, determining a first minimum forward time and a first minimum backward time. Further the method comprises determining a first correction factor. The method also comprises, applying the first correction factor to a clock provided at the second device and storing the first correction factor.

    摘要: The present invention provides a system and method for advising wireless computer networks on inter-network interferences during their life time. The method of the present invention initially observes initial channel utilization profiles along with corresponding time-slots of dynamic network elements and network characteristics of a first network and stores as historical channel utilization profiles. The initial transmission profiles an interfering second network are also recorded. The threshold transmission profiles are then recorded as historical transmission profiles. The aggregator determines interference patterns, by comparing historical channel utilization profiles with runtime threshold transmission profiles and advises and pre-warns appropriate network actions to a network manager of the first network on the interference prone zones. The system of the present invention includes a first network with a common multi-network interference observer, to advise on inter-network interferences.

    摘要: Systems and methods for configuring industrial devices through a secured wireless side channel may include a compute device. The compute device may have primary communication circuitry configured to communicate through a network and side channel communication circuitry configured to communicate through a wireless side channel that is different from the network. The compute device may additionally include circuitry configured to obtain, via the wireless side channel, configuration data indicative of a configuration for one or more operations of an industrial device of an industrial process plant. Additionally the circuitry may be configured to configure, in response to obtaining the configuration data, the one or more operations of the industrial device.

    摘要: A method for generating corrected measured current in an Intelligent Electronic Device (IED) that is a true representation of primary current in an electrical network is disclosed. The method uses regression and a first threshold on measured sampled values from CT to detect a deviation instance that indicates a possibility of saturation. Wavelet and second threshold based detection of instances of saturation is then done. Then a regression based correction that uses a dynamic correction factor is implemented in real time to obtain corrected sampled values i.e. corrected measured current. Ending of correction is done based upon a predetermined selection criterion, The generated corrected measured current is used for protection and control functions in the IED. A CT output re-generation module as a functional module in the IED for implementing the method as described above is also disclosed.
