IO= I/O status, connection status
LED display
Status/significance
Error handling
LED illuminated
green
– Normal operating status
– Communication with the controller
(PLC) OK
– Bus node is in operational mode and
is controlled by the PLC
– IOs are controlled via the PLC via
fieldbus/network
–
LED flashes
green (1 Hz)
– Operating status in preparation
– Bus node is in pre-operational mode
– Inputs/outputs (IOs) are in idle state
mode
–
LED illuminated
red
– Inputs/outputs (IOs) are in fail state
mode
– Typical cause:
usually an unrecoverable software
fault, e.g. no bus voltage
•
Check voltage supply to bus
Section 2.2.3
•
Read device diagnostics via fieldbus
communication (if activated via DIL
switches on the bus node)
•
Eliminate displayed faults
LED is flashing
red
– Inputs/outputs (IOs) are in fail state
mode
– PLC failure or stop
– Incorrect station number in the PLC or
on the bus node (incorrect DIL switch
position)
– Fieldbus/network interruption or
message failure
•
Check PLC
•
Check station number
Note
Station number (Node ID) 0 is not
permissible!
•
Check fieldbus/network connection
LED is off
– Fieldbus/I-port device not connected
– Commissioning of the bus node not
complete or not successful
•
Connect fieldbus/I-port device
•
Check fieldbus connection
•
Restart
