Described is a process for adjusting an operating interface, event messages, and/or measurement protocols belonging to internet-capable process devices, such as control units (13, 23), sensors (14), and/or actuators (15), to given operating conditions, which devices are connected over interfaces (3, 7, 20) and/or networks and form a component in a process control system. Also described is an arrangement with an interface of this kind. Thus, the invention makes possible an adjustment of the operating interface of internet-capable devices, particularly in process control systems, or of event messages and measurement protocols, to new operating conditions, an adjustment that is considerably easier for the user to manage.
