Label Position
The following terms are used to describe the state of the LEDs:
solid—on continuously in the defined state
flashing—each LED alternates between the two defined states (or
with OFF if only one state is defined). This only applies to a single
LED viewed independently of the other. If both ControlNet LEDs
are flashing, they flash together (in phase).
railroad—both LEDs alternate between the two defined states at the
same time. This only applies to both ControlNet LEDs when viewed
together. The two LEDs are always in opposite states (out-of-phase).
flickering—intermittent on/off between the two states, often in an
erratic pattern
