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.

Abstract: A unit is disclosed for validating a communication network of an industrial automation and control system. The validation unit can include a planner module configured to store plan data defining a designed communication network of an industrial automation and control system, and a collector module configured to collect effective data defining a deployed communication network of the industrial automation and control system. A difference detector can detect differences between the designed communication network and the deployed communication network using the plan data and the effective data such that faults or errors in a deployed communication network of the industrial automation and control system can be efficiently detected.
