Package: IoT

< prev | next >

Description: The IoT controller device Controller has been set to operate within safety limits in response to an interruption in real-time control inputs, such that it poses no danger to the physical system it regulates. This strategy represents activation of a contingency plan at runtime, and can be selected to discover what effect this would have on risk levels, allowing this to be used for decision support calculations. To activate it at runtime, signal user HostManager who is responsible for managing the device. The Safe IoT Controller control shoud be deselected only when the restrictions on Controller have been lifted.

Blocked Threats (1)

Co.U.CoPDS.0.2

Loss of reliability due to out of date input at Controller: if the onboard data at a controller is out of date, it means the controller will not be reliable unless it does not require real-time updates to operate safely.
