Abstract: A method for failure detection and role selection for a process in a network of redundant processes including a primary process configured to transmit a heartbeat signal with a predetermined interval to the processes of the network.

Abstract: A method for providing redundancy in a network centric process control system, where at least one node includes at least one control service as well as at least one middleware service for communicating in the process control system, where the control service and middleware service is each a separate executable running in a separate operating system process provided by a real time operating system thereof, wherein a first control service in a first node communicating via a first middleware service and implementing a first control function acts as an active control service for the first control function and a second control service communicating via a second middleware service and implementing the first control function acts as a standby control service for the first control function, the method including performing, by the first control service, the first control function through subscribing, via the first middleware service, to input process data of the first control function and publishing, via the first mid

Abstract: A method of connecting an isolated electric conductor to terminals of an apparatus where the electric conductor is drawn onto a fixture provided with holes arranged in correspondence with the terminals of the apparatus, from hole to hole and formed into loops through at least some of the holes. Then the terminals of the apparatus are inserted through the holes of the fixture and brought to contact against the inside of the loops where they are then attached.
