Technical installation data are visually preprocessed in a targeted manner in a control room or on a tablet with a touchscreen in mobile use by presenting a priority matrix. For this purpose, the interference messages are sorted, for example, horizontally with descending priority from left to right and vertically according to the installation part and are output. This largely relieves an operator of analysis and prioritization of the interference messages. The operator can therefore identify, locate and eliminate the most important interference messages in a shorter time. The number of priorities and installation parts considered is flexible since the matrix can be scaled to a wide variety of installation types, installation sizes and processes. All technical installation data relevant to assessing the situation are combined in one view. A second display area with a logical view is used to provide an overview of the complete industrial installation.
