Parameter identification for field devices used in automation technology

An apparatus for identifying parameters of at least one field device used in automation technology, comprising:

• a monitoring unit for monitoring the field device behavior and recording operating information describing the field device behavior;
• a first memory area for storing the operating information;
• a second memory area for storing a field device model simulating the operational behavior of the field device;
• and
• a processing unit for identifying model parameters belonging to the field device model based on the operating information so that the field device model to which parameters are assigned will exhibit similar system behavior as the field device,
• wherein the field device model is a vendor-neutral field device model,
• wherein the apparatus has a further processing unit to provide vendor-specific device parameters for the model parameters based upon target values, and
• wherein the further processing unit has a controller that determines the vendor-specific device parameters of a further field device based upon deviation from the model parameters determined for the further field device and target values for the model parameters.
