A manufacturing or service installation has a number of hardware devices for performing tasks. At least one such device has a computer or other means (14) for generating and reporting status data to a central computer (10) indicative of a status of the device or the installation. A memory associated with the device has a stylesheet for creating a pictorial representation of the device, whereby the central computer can access the stylesheet as well as the status data from the device, to create the pictorial representation and to populate the pictorial representation with the status data.
