Kurzfassung	Automation is used in factories to reduce manual labor. With an increasing level of automation, more and more devices are used to act, measure, and control the factory. Multiple vendors offer various device types with different functionalities; for example, motors for moving conveyor belts, sensors like light barriers, controllers to implement a specific behavior, and interface devices used to connect all devices and to reduce wiring. To enable the concurrent use of products of different vendors, they communicate with standardized protocols. To program a controller, an engineering tool is used to describe the topology of the system such that the programmer of the controller knows how to access data received from and how to send data to different devices. Device configuration files are imported into the engineering tool to provide information about the process data a device sends and expects to receive, about parameters that can be used to alter the behavior of a device, and about what diagnostic data the controller can expect from a device.Those configuration files are dependent on the protocol that is used for communication. One device type can support multiple protocols; therefore, multiple configuration files need to be provided for that device type. Since such configuration files can easily exceed thousands of lines in length, it is not efficient to write them by hand. Therefore, typically a generator is used to generate the configuration files based on some kind of description of the device type. We call the process of describing device types device type configuration and the system that is used for the process device type configuration system (DTCS). We propose a migration process from a database-based DTCS to a multi-level modeling DTCS. First, we analyze an industrial database-based DTCS to derive requirements for a DTCS. Then we present our migration process, which results in an FMMLx multi-level model with six levels. We evaluate the migration process with an expert survey. A model-driven approach enables model checking and consistent device types. Multi-level models enable the reuse of parts of the domain specific language.
