And this is what runs our infrastructure. This is what runs everything around us. PLC's, these small boxes which have no display, no keyboard, which are programmed, are put in place, and they do their job.
Y esto es lo que sostiene nuestra infraestructura; ejecuta todo lo que nos rodea. estos PLC que son cajitas sin pantallas, ni teclados, que se programan, se instalan y hacen su trabajo.
