Abstract
The invention relates to a field device for connection to a programmable logic controller having hardware comprising a processing unit, a memory and a data interface for communication with the programmable logic controller. The field device is characterized in that it is configured to receive compatibility information from the programmable logic controller by means of the data interface, wherein a firmware having a plurality of functions for operating the field instrument is stored in the memory, wherein the processing unit is configured to release a subset of the functions of the firmware for execution in dependence on the compatibility information to produce a behavior of the field device which is adapted to the compatibility information of the programmable logic controller.
