Abstract:
The invention relates to a unit (10) for validating a communication network of an industrial automation and control system. The validation unit (10) comprises a planner module (11) configured to store plan data defining a designed communication network of an industrial automation and control system and a collector module (12) configured to collect effective data defining a deployed communication network of the industrial automation and control system. The validation unit (10) further comprises a difference detector (13) configured to detect differences between the designed communication network and the deployed communication network using the plan data and the effective data. Accordingly, faults or errors in a deployed communication network of the industrial automation and control system can be efficiently detected.
Abstract:
A device (D) for validating reachability of nodes of a communication network of an industrial automation and control system (N) comprises: a collector module (C) configured to update a data set including discovered dataflow information (F) by performing the steps of: detecting direct neighbour nodes having a physical connection to a selected node, and updating the data set including discovered dataflow information (F) by adding the selected node and those direct neighbour nodes which have configured logical network constraints matching logical network constraints of the selected node, a repeater module (R) configured to repeat the steps of: selecting a direct neighbour node in the data set including discovered dataflow information (F) and directing the collector module (C) to update the data set including discovered dataflow information (F) using the selected direct neighbour node, and a validation module (V) configured to validate reachability of nodes of the network (N) by comparing the data set including discovered dataflow information (F) with a data set including designed dataflow information (Q) which defines reachability requirements for nodes of the communication network (N).
Abstract:
A protection scheme for a distribution feeder 12 is proposed that may combine information from all power sources 16, 18 on the feeder 12 and may provide optimal protection under all configurations of local power sources 18 without requiring an update or adaptation of the feeder protection to the current configuration.
Abstract:
The invention relates to a verification device (20) for automatically verifying communication redundancy in a high availability automation network (10, 11). The high availability automation network (10, 11) comprises a plurality of communication links redundantly arranged between ports of a plurality of network nodes (1-7). The verification device (20) comprises: a node collector (21) configured to collect inter-port connectivity information from the network nodes (1-7) of the high availability automation network (10, 11), a topology generator (22) configured to determine a network topology of the high availability automation network (10, 11) using the collected connectivity information of the network nodes (1-7), and a verification module (23) configured to verify the communication redundancy in the high availability automation network (10, 11) by analyzing the determined network topology of the high availability automation network (10, 11) with regards to redundancy rules.
