1. A method for extending an embedded software component of a field device, comprising the steps of:
- loading an extending software component into a memory of the field device;
providing by means of the extending software component at least one supplemental application function for the field device; and
interacting the embedded software component and the extending software component, in order to execute the supplemental application function, wherein;
said embedded software component is embodied to ascertain a presence of said extending software component and to adapt the program execution in order to execute said function contained in said extending software component;
the field device is connected with a servicing device, which contains the extending software component, a component serving for encryption and authentification connected with a communication driver; and
the extending software component is fed to the component serving for encryption and authentification and transmitted from the servicing device to the field device.
