ControlNet Channel Status Indicators

The ControlNet channel status indicators appear in one of these

states:

• Steady - indicator is on continuously in the defined state.

• Alternating - the two indicators alternate between the two

defined states at the same time (applies to both indicators

viewed together). The two indicators are always in opposite

states, out of phase.

• Flashing - the indicator alternates between the two defined

states (applies to each indicator viewed independent of the

other). If both indicators are flashing, they must flash together,

in phase.

The Indicator States table summarizes the meanings of these states.
