The allocation of hardware resources to distribution applications is enabled without using effective task priority available only in field devices. All of the feed air is compressed in the main air compressor to a first air pressure which is at least 3 bar higher than the operating pressure of the high-pressure column. The composition of the material is changed during application of the coating such that the percentage of the ferrite or rare earth compound is increased.
