Abstract: The present invention relates to a plant information system (1) with means (2) for acquiring a plurality of process information data (PI) from automation devices (5), systems (5), diagnostic devices (5), systems (5) and/or other devices (5) of a plant, and means 3b) for editing and/or presentation of the acquired process information data (PI). The plant information system (1) is characterized by means (1b) for selection, in accordance with criteria specified beforehand, of specific process information data from the plurality of process information data (PI). In this way, and with the corresponding inventive method, specific process information data from the plurality of acquired process information data (PI) which is of particular relevance for process execution or for a user can be selected, if necessary evaluated and displayed to the user.

Abstract: The embodiment of a respective application-specific call code, necessary in the existing art, as an external control element implemented in a separate component is described. The external control element is usable in any desired containers without thereby modifying the containers themselves or even knowing them at the time the external control element is designed. This may be used in data or information transmission systems, in particular process visualization systems. The components are implemented as software components, in particular as so-called ActiveX controls.
