Abstract: A method for controlling an electric motor with a softstarter. A softstarter device for control of electric motors. Motor torque is controlled in dependence of a torque error signal, based on a calculated difference between the motor torque and a reference torque value, so that the motor torque displays a rate of change with respect to time, during a stopping or starting time interval, that is adapted to follow a rate of change of the reference torque value, with respect to time, that varies between at least a first part of the time interval and a second part of the time interval, and thereby changing the speed of the motor. A system includes an electric motor, a device driven by the electric motor and a softstarter device for controlling the electric motor. A computer program product includes a computer readable medium and a computer program recorded thereon.

Abstract: Methods and devices for performing a selection action of information in a central system before communicating selected information to a user terminal. The selection is based on at least the identity of the user and position of the user terminal. Using relations between identity and profiles, a first information filtering can be achieved. Using relations between the actual position of the user terminal and constitution of the industrial automation facility, information irrelevant for parts in the vicinity of the user terminal is removed. The operational situation of the facility and history of user actions may be used for filtering or prioritizing the information. The most prioritized data quantity is communicated to the user terminal and displayed at a user terminal display. If all the data, despite sifting, is too extensive to be shown at once on the user terminal, the user may move between different parts of the relevant information.

Abstract: The present invention discloses methods and devices, with which a selection action of information is performed in a central system before communicating the selected information to a user terminal. This selection (4,6) is according to the invention based on a least both the identity (9) of the user and the position (11) of the user terminal. By using relations between identity (9) and profiles (8) a first information filtering can be achieved. By further using relations between the actual position (11) of the user terminal and the constitution of the industrial automation facility, information irrelevant for the parts in the vicinity of the user terminal is removed. Preferably, also the operational situation of the facility and the history of the user actions are used for filtering or prioritising the information. The most prioritised data quantity is communicated (12) to the user terminal (13) and displayed at a user terminal display.
