A supermarket may have 30 freezers. You don't want them to beep loudly if someone forgot to close the door. Instead you connect them to a central monitor. A local employee can see on the monitor which freezer has a problem and go see the issue.
The monitoring is as well a proof that the cold chain was kept.
This network was local to the market. Then one day it was found better to collect these data to a modern dashboard, and so the local network ends on corporate network.
