Abstract
A method for verifying field device inventory includes connecting a processing unit to a network; reading the address space of the network using the processing unit to generate a list of field devices contained in the address space; establishing communication between the processing unit and a field device contained in the list; reading out identification information of the field device using the processing unit, the identification and a characteristic parameter of the field device; carrying out a consistency check, a negative result being achieved if a field device is already entered under the serial number that has been read out; checking, if a negative result, whether a characteristic parameter of the field device corresponds with the characteristic parameter that has been read out; and outputting a notification using the processing unit that a characteristic parameter assigned to the field device deviates from the parameter that has been read out.
