  • Patent number: 10601650
    Abstract: The present application is concerned with a method for loading configuration data to a first Intelligent Electronic Device IED in a Substation Automation SA system, wherein the SA system included a second IED connected to the first IED via a communication network. The method includes: determining a first SID for the first IED by means of a neighbour ship relation, wherein the neighbour ship relation is predefined and indicative of a relative arrangement of the first and second IED in the communication network; assigning the first SID to the first IED; and obtaining first configuration data corresponding to the first SID, and loading the first configuration data to the first IED. The Global Identification GID of the first IED may be determined from the communication network, and the first SID can be linked with the GID of the first IED. The present application concerns also an active IED for configuration of a new or replaced IED in the substation system, according to the above mentioned method.

  • Patent number: 9906379
    Abstract: A method is disclosed for providing a network bridge between a source and a receiving network of a communication network, wherein the network bridge includes two content-bridging nodes connected between the source and the receiving networks according to a redundancy schema defined in IEC62439-3. The method can include assigning a common source network node identifier to the two content-bridging nodes; receiving, by each of the two content-bridging nodes, network traffic within the source network; and forwarding, by each of the two content-bridging nodes using the source network identifier, the network traffic from the source to the receiving networks.

  • Patent number: 9473384
    Abstract: A device validates reachability of nodes of a communication network of an industrial automation and control system. The device includes a collector module configured to update a data set including discovered dataflow information by detecting direct neighbor nodes having a physical connection to a selected node, and updating the data set by adding the selected node and those direct neighbor nodes which have configured logical network constraints matching logical network constraints of the selected node. The device includes a repeater module configured to repeat the selecting of a direct neighbor node in the data set and directing the collector module to update the data set using the selected direct neighbor node. The device includes a validation module configured to validate reachability of nodes of the network by comparing the data set with a data set including designed dataflow information which defines reachability requirements for nodes of the communication network.
