Claim 0:
1. A method for verifying the field device inventory entered in an asset management system, wherein a plurality of field devices is integrated into a first communication network, comprising:
connecting a processing unit to the first communication network;
reading out the address space of the first communication network using the processing unit in order to generate a list of all field devices contained in the address space;
establishing communication between the processing unit and a field device contained in the list, via a communication path in the first communication network;
reading out identification information of the field device using the processing unit using the established communication, wherein the identification information includes at least a serial number of the field device and a characteristic parameter of the field device;
performing a consistency check in the asset management system, wherein a negative result of the consistency check is achieved if, in the asset management system, a field device has already been entered under the serial number that has been read out;
checking, in the event of a negative result of the consistency check, whether a characteristic parameter associated with the field device in the asset management system corresponds with the characteristic parameter that has been read out; and
outputting a notification of a need for action by means of the processing unit in the event that, in the asset management system, a characteristic parameter associated with the field device deviates from the characteristic parameter that has been read out.
