Let’s refer to a meteorological application based on remote measuring stations; in this
case the remote unit is required to initiate a protective closing operation that prevents damage being caused to cold-sensitive measuring equipment each time the
temperature drops below minus 20ºC. The programmer’s software error defines the
lower temperature limit as minus 30ºC. The meteorological information system
purchased by several Spanish organizations was installed in various sites in Spain,
none of which suffers from low temperatures. The fault only turned into a failure once
a Russian version of the system had been developed and installed in various northern
sites of Russia, causing severe damage to the measuring stations’ equipment.
