Shutdown systems typically use equipment that is SIL 2 certified as a minimum, whereas control systems can start with SIL 1. SIL applies to both hardware and software requirements ...
Bluetooth File Exchange is a utility that comes with the macOS operating system, used to exchange files to or from a Bluetooth-enabled device. [56] For example, it could be used to send an image to a cellphone, or to receive an image or other documents from a PDA.
Fail-secure systems maintain maximum security when they cannot operate. For example, while fail-safe electronic doors unlock during power failures, fail-secure ones will lock, keeping an area secure. Fail-Passive systems continue to operate in the event of a system failure. An example includes an aircraft autopilot. In the event of a failure ...
