ControlNet Network Channel Status Indicators

The ControlNet network channel status indicators appear in one of the
following 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 ControlNet Network Channel Status Indicators table summarizes the
meanings of these states.
