A system in which a method is employed for replacement of a field device to be replaced by a new field device, comprising:

• an electronic control unit;
• and
• a fieldbus through which the electronic control unit communicates parameters, information and/or values of the new field device with respect to at least one data record, wherein the electronic control unit is capable of comparing previous parameters, information and/or values of the field device to be replaced, and modifying the parameters, information and/or values of the new field device with respect to at least one data record to match the field device to be replaced.
