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.

Redundancy in an automation system covering more than one system area

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.

Limiting cellular network influence on latency in an industrial automation system

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.

Method for operating intelligent electronic device and an intelligent electronic device

A method for enabling communication of data relating to samples of electric measurements, the method being performed in an intelligent electronic device, IED, including a cellular radio module, the IED being configured to protect power system equipment. The method includes the steps of: detecting channel quality using the cellular radio module, the channel quality relating to a channel between the IED and a base station; transmitting packets using the cellular radio module, each packet including data relating to samples of electric measurements for protecting power system equipment; and increasing sample rate of the electric measurements when the channel quality is worse than a first threshold.

Intelligent electronic device comprising a cellular radio module

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.

Enabling communication between a communication devices of a substations

A method performed by a wireless terminal for installation of Building Automation (BA) devices in a building includes: determining, using a localization application in the wireless terminal, a current location of the wireless terminal in the building; from a BA device database, obtaining an identifier for each of a plurality of the BA devices which should be installed in a vicinity of the determined location of the wireless terminal; presenting a list of the obtained identifiers in a user interface of the wireless terminal; after the presenting, receiving input via the user interface; and in response to the received input, associating at least a first of the plurality of BA devices with at least a second of the plurality of BA devices.

Installation of building automation devices

A method for managing communication with a building automation device, the method being performed in a gateway, the method including the steps of: establishing communication with the building automation device over a first communication protocol; installing executable software instructions on the building automation device over the first communication protocol to provide a capability to communicate over a second communication protocol; and establishing communication with the building automation device over the second communication protocol.

Managing communication between gateway and building automation device

A method for managing communication with a building automation device, the method being performed in a gateway, includes the steps of: receiving a packet from the building automation device; determining that the gateway currently fails to support a communication protocol being compatible with the packet; transmitting the packet to a protocol server; receiving, from the protocol server, executable software instructions to be used for communication over the communication protocol being compatible with the packet; and installing the executable software instructions to provide a capability to communicate over the communication protocol being compatible with the packet.

Managing communication between gateway and building automation device by installing protocol software in gateway

A wireless terminal for receiving a health report from a wireless communication network comprising a group of network nodes communicating within the wireless communication network using a first communication technology employing a first frequency band includes: a first wireless interface for communicating according to a second communication technology employing a second frequency band; and a terminal control unit for receiving, via the first wireless interface, at least one health report with health data from at least a first node in the group of network nodes triggered by a health report sending condition being fulfilled in the wireless communication network.

Health report sending from a wireless communication network

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.
