"BUS-F" LED
The "BUS-F" LED indicates the physical state of the bus node. The functionality is de-
scribed in the following table:

No error
The number of bus errors is with-
in the normal range (error active
state).

Bus
warning
The unit is performing a DUP-
MAC check and cannot send any
messages because no other sta-
tions are connected to the bus
(error passive state).
• Integrate another
DeviceNet™ station
into the network.
• Check the wiring and
terminating resistors.
Red
Illuminated
Bus error Bus off status.
The number of physical bus er-
rors has increased despite
switchover to error-passive state.
Access to the bus is switched off.
• Check the setting for
the address baud rate,
wiring, and terminating
resistors.
Yellow
Illuminated
Power off External voltage supply has
been turned off or is not connec-
ted.
• Check the external
voltage supply and
wiring of the unit.
