Estimating the term…
A field device having at least one memory and at least two replaceable modules, each of which has hardware and firmware associated with the hardware. In such case, firmware version information of a compatible firmware version combination of the modules of the field device is stored in the at least one memory or such is storable therein at a first-time start-up of the field device. Furthermore, the field device is embodied in such a manner that a comparison in the case of at least one module of its firmware version with the firmware version information stored in the memory is automatically performable and that the module is automatically switchable to the firmware version as claimed in the firmware version information, in case the comparison shows a deviation of the firmware version of the module from the firmware version of the firmware version information stored for the corresponding module.
