Abstract
A control system for an industrial plant receives plant data and combines that plant data with a plurality of graphical patterns representing the plant. In this way a series of prepared displays are created to be displayed fox a user of the control system. If the user wants to simplify one or more of the displays, in order to make it more clear, the control system has means for modifying the displays, and displaying that modified display. The modification may be one of a number of possibilities such as deletion (masking) part or all of the display. In this way, the full plant information may be presented, or more limited information may be presented, e.g. to a more experienced user.
