A monitoring system for an electrical transmission and/or distribution network is disclosed. The system comprises a short-range wireless transceiver arranged at a predetermined position relative to an equipment device and configured to receive a signal from a portable device, and a controller configured to determine a location of the portable device based at least partially on the received signal. The controller is further configured to verify if the determined location is within a predetermined alert zone at least partly surrounding the equipment device, and to generate an alert signal in case the determined location is verified to be within the alert zone.

A method for a remote procedure call can be used between entities in a service bus communication system that includes a first consumer, a data exchange system and a number of publishers. The method includes receiving a first request for data from the first consumer at the data exchange system, transmitting the first request from the data exchange system to the plurality of publishers, receiving, by the data exchange system, a first reply to the first request for data from a first publisher of the plurality of publishers, and transmitting the first reply from the data exchange system to the first consumer.

A method for positioning a virtual object in an image of a scene including a real object is disclosed. The method comprises receiving a signal from a short-range wireless transmitter arranged at a predetermined position relative to the real object and determining a location and orientation of the portable device relative to the short-range wireless transmitter based on the received signal. The image of the scene is displayed with the virtual object, wherein the position of the virtual object in the image is based on the determined location and orientation of the portable device relative to the short-range wireless transmitter and on the predetermined position of the short-range wireless transmitter relative to the real object. A system, a portable device and a computer program product is also disclosed.

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.

Method and access unit for accessing industrial communication networks

A method and device for configuring an intelligent electronic device, IED, hosting a logical node instance are provided. Incoming signals of the IED are bound to inputs of a function, the function being performed by the logical node instance in operation of an industrial automation control system, IACS. To bind the incoming signals to the inputs of the function, a computing device determines, based on an input data template of the logical node instance, which data is required by the logical node instance to perform the function. The computing device determines, using process related information of the IACS, source IEDs of the IACS that provide the data required by the logical node instance to perform the function.

Method, device, and computer program for configuring an intelligent electronic device

The present application is concerned with a method for loading configuration data to a first Intelligent Electronic Device IED in a Substation Automation SA system, wherein the SA system included a second IED connected to the first IED via a communication network. The method includes: determining a first SID for the first IED by means of a neighbour ship relation, wherein the neighbour ship relation is predefined and indicative of a relative arrangement of the first and second IED in the communication network; assigning the first SID to the first IED; and obtaining first configuration data corresponding to the first SID, and loading the first configuration data to the first IED. The Global Identification GID of the first IED may be determined from the communication network, and the first SID can be linked with the GID of the first IED. The present application concerns also an active IED for configuration of a new or replaced IED in the substation system, according to the above mentioned method.

Method for automated configuration of an IED

The present disclosure is concerned with a Substation Automation testing tool which combines the information found in the SCL (Substation Configuration Language) File of a substation (Substation Configuration Description) or an IED (IED Capability description) with substation-relevant data extracted from the Substation Communication network traffic. Using a message interceptor, e.g., a laptop computer, connected to a substation communication network, IEC 61850 relevant data is retrieved and analyzed. Hence, consistency verification without revision handling and a reduction of the time and efforts for commissioning or testing a substation installation are possible.
