    Abstract: A method for enabling communication over a cellular network between a first communication device of a first substation and a second communication device of a second substation. The substations are connected to a power transmission line. The method includes the steps of: receiving multicast communication from the first communication device, wherein the multicast communication including a plurality of multicast packets, and each multicast packet includes a phasor value associated with the first substation and a sequence number; receiving an acknowledgement from the second communication device, the acknowledgement including a plurality of sequence numbers of the most recently received multicast packets, that the second communication device has received from the first communication device; and determining a packet loss to the second communication device when there is a mismatch between the sequence numbers of the acknowledgment, when compared with the sequence numbers of the received multicast communication.

    Abstract: A method includes transmitting time-critical messages in an OSI layer 2 network tunnel from a first IED in a first substation to a second IED in a second substation over a WAN, wherein each of the first and second substation comprises an edge IED and is associated with a substation LAN, wherein each of the time-critical messages comprises message parameters. The method includes: creating a translation table comprising corresponding values of the message parameters, between the LANs and the WAN; defining a virtual IED in the second substation using the translated values of the message parameters, to impersonate the first IED; translating the message parameters according to the translation table, by the edge IED of the first and second substation; forwarding the time-critical messages from the first IED in the first substation to the WAN; and receiving the time-critical messages by the second IED in the second substation from the WAN.

    Abstract: In an industrial automation system including a first and a second wireless communication device communicating with each other via a cellular network, the first wireless communication device obtains, while the first wireless communication device is attached to a first base station of the cellular network, knowledge about to which base station the second wireless communication device is attached and if the second wireless communication device is attached to a second allowable base station, the first wireless communication device detaches from the first base station and attaches to the second base station.

    Abstract: An automation system includes a first system area including a transmitting redundancy handling device and a second system area including a receiving redundancy handling device. Device obtains a first communication protocol packet with automation application data and a sequence number linked thereto, extracts the sequence number and places it in a destination option header of a first IPv6 packet, which also includes the first communication protocol packet, sends packet to the receiving redundancy handling device, obtains a second communication protocol packet having the same automation application data and sequence number, places the sequence number in a destination option header of a second IPV6 packet also including the second communication protocol packet, and sends packet to device. Device receives the packets, analyses the destination option headers, determines that the sequence number is the same in the packets and discards the first or the second IPv6 packet based on the determination.

    Abstract: A method of operating an intelligent electronic device that is in a wireless communication with a base station of a wireless communication system is described. The method includes monitoring at least two QoS parameters of the wireless communication and controlling the operation of the intelligent electronic device based on the at least two QoS parameters, wherein the intelligent electronic device includes a wireless communication module, wherein the wireless communication is carried out between the wireless communication module and the base station of the wireless communication system, and wherein the at least two QoS parameters are determined at least in part in the wireless communication module and are transferred to a control module of the intelligent electronic device over an interface.
