Abstract: To configure an Internet of Things, IoT, device for collecting data from industrial devices, the IoT device is coupled to a IoT platform. The IoT platform stores device twin data of the industrial devices. The device twin data includes configuration information. The IoT device retrieves the configuration information from the device twin data stored in the IoT platform and uses the configuration information for collecting data from the industrial devices.

Abstract: A method and an access unit for accessing an industrial communication network are provided. An access unit has first ports connected to the communication network and at least one second port. The access unit is configured to pass data traffic between nodes of the communication network through the access unit in a first operational state of the access unit. The access unit is configured to pass data traffic to a test node via the at least one second port and/or allow test data to be injected into the communication network via the at least one second port in a second operational state of the access unit.

Abstract: The invention relates to a method for analyzing an abnormal event in an industrial automation and control system, IACS, comprising the following steps: identifying the abnormal event; detecting a root cause of the abnormal event; and generating a notification if the root cause is not a user activity and, if the root cause is a user activity, evaluating the possible impact on the IACS caused by the abnormal event, and generating a notification if the evaluation of the possible impact does not match a predefined list of allowable behavior. The present invention also relates to a corresponding system and corresponding computer program product comprising one or more computer readable media having computer executable instructions for performing the steps of the method.
