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.
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 neighbour nodes having a physical connection to a selected node, and updating the data set by adding the selected node and those direct neighbour 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 neighbour node in the data set and directing the collector module to update the data set using the selected direct neighbour 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.
