Interface Module and Method for Configuring and Parameterizing a Field Bus User

A method for configuring and parameterizing a field bus user which is connected via an interface module to a field bus and which is linked to an engineering system comprising a configuration tool, with which for the field bus user with at least one module slot for connection of at least one of sensors and actuators, logical addresses for accessing process data of at least one of the sensors and actuators are issued in a configuration file and, via the configuration tool, an application relation is at least temporarily created between the engineering system and the interface module, the method comprising:

• transforming the logical addresses on a side of the engineering system with a transformation device into virtual addresses which are not physically present such that, a transformed virtual configuration file comes into existence, which is transmitted via the field bus to the interface module aided by the application relation;
• recognizing in the interface module, via a recognition device, whether the virtual addresses are present in the received virtual configuration file;
• triggering a signal upon recognizing that the virtual addresses are present in the received virtual configuration file to ensure that the virtual configuration file is adopted and is stored in a non-volatile manner in a configuration store within the interface module;
• and
• transforming the virtual addresses in the interface module via a reverse transformation device back into physically present addresses comprising the logical addresses, whereby for a data exchange of the process data of the module slot, on a request by further field bus users, the process data in the module slot is addressed.
