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.
