  • Patent number: 9478973
    Abstract: An exemplary method and system are disclosed for coordinated transfer of control in a substation system having IED or logical devices/servers using GOOSE messages with preconfigured data models with logical nodes containing one or more data objects including private data objects (DO) connected in the substation communication network. The method for transfer of control can be illustrated for hot-standby device management and for other applications such as logical isolation of merging unit in a substation and load sharing between IEDs. The method can be used for devices that do not have MMS stack.

  • Patent number: 8942970
    Abstract: A method is disclosed for configuring an intelligent electronic device (IED) that includes enabling dynamic capability of the IED by a flexible data modeling technique to dynamically adapt a data model based on an application requirement using a configuration tool. A substation automation system is also disclosed which includes a local system equipment having a plurality of IEDs associated with the local system equipment and an IED configuration tool configured to interact with the firmware of each IED to configure the IED based on application requirements. The application configuration tool can include dynamic capability information of the IED to enable a flexible data model in the IED.

  • Patent number: 8880658
    Abstract: A method, a substation automation apparatus and an intelligent electronic device (IED) are disclosed which are, for example, not limited only to publishing data (data emanating) from the IED. An exemplary method includes assigning a unique identifier to one or more data fields, where the one or more data fields is associated with a short address attribute in the data emanating from the intelligent electronic device; and dynamically updating the identifier based on user specific configuration data by an IED application configuration tool. The IED can include a list of functions; (e.g., each function being represented as a logical node; and each logical node containing data objects); and a flexible addressing scheme for configuring the data objects and publishing data from the IED, but not only data emanating from IED.

  • Patent number: 8225020
    Abstract: Certain aspects of a method and system for a hardware-based implementation of USB 1.1 over a high-speed link may comprise translating at a client side of a client server communication system, USB protocol messages comprising a first USB standard to corresponding encapsulated USB protocol messages, wherein the USB protocol messages comprising the first USB standard are received from a client device at the client side of the client server communication system. The translated corresponding encapsulated USB protocol messages may be communicated from the client side to a server at a server side of the client server communication system.

  • Publication number: 20070011374
    Abstract: Certain aspects of a method and system for universal serial bus (USB) re-direct (USB-R) over a network may comprise receiving at a local client device via a network, remote client device detection data corresponding to a remote client device that is plugged into a remote system. The local client device may request access to the remote client device that is plugged into the remote system by communicating device access data. The remote client device that is plugged into the remote system may be mapped as a USB device at the local client device. The local client device may receive information from the remote system via the network, confirming the requested access to the remote client device that is plugged into the remote system.

  • Patent number: 6295570
    Abstract: A method for using a driver program to communicate with multiple serial bus devices includes selecting one of the serial bus devices and automatically coupling the selected serial bus device to a computer. The other serial bus devices are isolated from the computer, and the driver program is executed to communicate with the selected serial bus device.
