The present disclosure relates to a framework application for device access software. The framework application can be installed on a host. At least one driver can be integrated into the framework application, said driver being designed for access to an associated field bus component of a field bus network. For each integrated driver, the framework application has a standard interface, via which data can be exchanged between the driver and the framework application. For at least some of the integrated drivers, the framework application has one or more proprietary interfaces in addition to the standard interface, via which proprietary interfaces data can be exchanged between the respective drivers and the framework application. Information regarding additional functionalities that are supported by the driver or by an associated field bus component can be transferred from the driver to the framework application via at least one of the proprietary interfaces.
