Diagnostic LEDs
The ControlNet Network Communication Option board has three bicolor (red/green)
LEDs. The Health LED indicates the status of the network communication board and
each of the two Communications LEDs indicates the status of its associated channel.
The Health LED provides the status of the network option board. It indicates whether
or not the board has power and is operating properly.
The Communications LEDs can be off, red, green, or some alternating pattern. In
table 6.2, the term “flashing” is used to describe LEDs that are always in the same
state, or in phase. The term “alternating” is used to describe LEDs that are always in
opposite states, or out of phase.
