    Abstract: A control network for supporting multiple industrial automation devices which operate in radio coverage of at least one radio access network includes: a processor configured to execute applications; at least two wireless network interfaces, each configured to communicate with the automation devices; and a traffic controller configured to provide a logical connection from an executing application to one of the automation devices by maintaining at least two contemporaneous physical connections using respective wireless network interfaces and the radio access network. The control network is further configured to repeatedly adapt a physical redundancy of the logical connection. In some embodiments, the control network is configured to determine a level of independence between the physical connections on the basis of measurements, and adapt the redundancy accordingly. The level of independence may be determined by comparing time series of a quality-of-service related quantity.

    Abstract: There is provided mechanisms for transmission of packets over a TSN aware network. A method is performed by a network node. The method includes obtaining a traffic flow of packets from a non-TSN aware network interface. The method includes extracting, from the packets and at above OSI protocol layer 2, information indicative of which traffic class the traffic flow belongs to. The method includes mapping the traffic class to a TSN traffic class or priority. The method includes associating the packets with an indicator of the TSN traffic class or priority. The method includes providing the traffic flow of packets, including the indicator, to a TSN aware network interface for transmission of the packets over the TSN aware network.

    Abstract: A mechanisms for analyzing event based behavior of end-points of a network in an industrial system and a method performed by a control node, the method includes collecting, from the end-points, timestamped event log entries as created by the end-points within a time window. Each respective timestamped event log entry pertains to a respective event performed by one of the end-points. The method includes identifying tuples of correlated events by comparing the timestamped event log entries to each other, thereby providing a mapping between the events and those end-points where the events of each tuple of correlated events are performed.

    Abstract: There is provided mechanisms for configuration of parameters for a networked device to be provisioned in a network. A method is performed by a device configuration node. The method includes obtaining a request for configuration of parameters for the networked device. The request indicates that the networked device is of a certain device type. The method includes selecting a template from a set of templates stored in a database. The template is selected based on the certain device type. The method includes providing configuration of at least a subset of the parameters for the networked device based on the template.

    Abstract: A method for handling failure of a TSN communication link in a TSN network. The method is performed by a control node and includes estimating requirements for TSN communication for end-points based on application parameters, input/output requirements, and application requirements, wherein each end-point is capable of communicating over a TSN channel and a non-TSN channel in the TSN network using one and the same network interface. The method includes obtaining an indication of a failure of a TSN communication link in the TSN network between two of the end-points. The method includes performing self-healing of the TSN communication link.

    Abstract: A method, arrangement, computer program and computer program product for improving communication between devices of an industrial automation system running automation applications as well as to such an industrial automation system. The devices include a first and a second endpoint device of a communication path for a data stream through a time sensitive network and for which a corresponding application has an application cycle time at which the first and second endpoint device are to transmit data to each other. The first endpoint device detects a communication degradation of the data stream, which communication degradation is indicative of congestion and performs a congestion limiting activity from a group of congestion limiting activities, which group at least includes an activity of increasing the application cycle time of the data stream.
