Summary:The invention relates to a field device (10), in particular a protective device, having a microprocessor arrangement (20) which executes a program module (PM), which defines the device function, during operation of the field device. The invention provides for the field device to have a protection device (40) which is configured in such a manner that it checks whether a function description block (FB), which has been input and describes a desired device function, describes an enabled device function and, in the case of a device function which has not been enabled, blocks execution of said function and, in the case of a device function which has been enabled, enables execution of said function.
