With the assistance of the enabling codes, special-functionalities can be enabled in field devices. Associated with individual enabling codes of the enabling code set is, in each case, an attribute, “free” or “blocked”. If a special-functionality is needed, then an enabling code is transmitted to the field device, in case an enabling code with attribute “free” is present. Following transmission, the attribute of the transmitted enabling code is changed from free to blocked. The method permits enabling code to be used very flexably.	08-20-2009
