The ControlNet channel status indicators appear in one of these
states:
•
Steady - status indicator is on continuously in the defined
state.
•
Alternating - while viewed together, the two indicators
simultaneously alternate between the two defined states. The
two indicators are always in opposite states, out of phase.
•
Flashing - when each status indicator is viewed apart from the
other, each status indicator alternates between the two defined
states. If both indicators are flashing, they must flash together,
in phase.
