Diagnostics and error handling
6.1
LEDs
The Bus Coupler has two groups of LEDs for the display of status. The upper group (BK3xx0) or left hand
group (LC3100) indicates the state of the fieldbus.
On the upper right hand side of the BK3xx0 Bus Coupler are two more green LEDs that indicate the supply
voltage. The left hand LED indicates the presence of the 24 V supply for the Bus Coupler. The right hand
LED indicates the presence of the supply to the power contacts. The two K-Bus LEDs (I/O RUN, I/O ERR)
are located under the fieldbus LEDs. These indicate the operational state of the Bus Terminals and the
connection to these Bus Terminals.
Fieldbus LEDs
The upper three LEDs (or the two LEDs on the left) indicate the operating state of the PROFIBUS
communication:
