Abstract
A method for automatically registering a topology of a fieldbus network from a device access software. The device access software is installed in a host, which is in data connection with the fieldbus network, and the fieldbus network includes a plurality of field devices and gateway devices. The method includes scanning an address space of a field access device or a predetermined gateway device of the fieldbus network and determining gateway devices and field devices present in this address space. For each found gateway device, the method includes scanning an additional address space provided by the found gateway device and determining additional gateway devices and field devices present in the additional address space. The method is repeated until all gateway devices present in the fieldbus network in the region below the field access device or the predetermined gateway device are found or until a break condition is fulfilled.
