A first component of an industrial automation system includes an electrically erasable programmable read-only memory (EEPROM) storing data identifying the first component. The data identifying the first component is read from the EEPROM by a second component to which the first component is communicatively coupled to authenticate the first component. The first component lacks a processor and a microcontroller, and does not run firmware.

An information processing apparatus includes: a controller that outputs notification information based on input information; and a processor that executes system processing based on an operating system (OS) and operation of thermal control processing by control of a Basic Input Output System (BIOS) using the notification information output from the controller. The controller accepts an operation signal indicative of an operated key according to a user's operation on a keyboard; determines whether the operated key is of a specific combination of keys based on the accepted operation signal; upon making a determination that the operated key is of the specific combination of keys, outputs, to the processor, a result of the determination as the notification information; and without another key being pressed after the result of the determination is output from the controller, the processor executes the thermal control processing based on the result of the determination.
