Warm Boot Detection

The microFLUX has the ability to distinguish a normal "cold" boot and an unexpected "warm" boot. When a warm boot is detected the previous output state is retained to ensure that power supply is not interrupted.

Events such as a software crash, momentary voltage drops causing a brownout, excessive EMI and cosmic radiation could all potentially cause an unexpected restart.

When a warm boot is detected, the former channel states (output on/off and voltage level) are retained. The "Power On At Startup" setting will be ignored on a warm boot.

If, through output states and device configuration, it can be confirmed that the device was armed prior to the restart, then the device will act as if an arming message was received on startup. In many cases, arming prior to a restart cannot be confirmed, therefore channels that are configured to "Power On Upon Arming" will not be turned on automatically if the device arms within 2.5 seconds of a warm boot.
