19.4 Alarm WSX
Figure 1.
The following table describes how WSX uses LED1 (Power) to indicate the current system state. LED1 is also used to indicate the status of the threads in the application layer.
When all threads run as expected, LED1 blinks slowly at a constant speed. If one or several of the application threads don’t function correct, LED1 stops blinking.
