A control and monitoring system is adapted to collect parameter data from networked devices, and to display representations of the system or monitored data in a number of selectable languages on a monitoring station. Textual labels for the representations are stored in a system database. Component and system data may also be stored in the database for use in identifying and monitoring the components. The language used for the labels is selectable by a user via a menu, and the corresponding entries in the database are used in building the representations. The language may thus be changed in real time without interrupting the monitoring and control functions of the components or the monitoring station.
