FAULT
red
Off
as an IO controller:
● PROFINET interface is operating without error; the data exchange to
all configured IO devices is running
as an I‑Device:
● PROFINET interface is running without error, there is at least one
communication link with the I‑Device
On
PROFINET interface bus fault
● No physical connection to a subnet/switch
● Incorrect transmission rate
● Full duplex transmission is not activated
● More than one IP address/NameOfStation in the network
Flashing
(2 Hz)
as an IO controller:
● Failure of a connected IO device
● At least one of the assigned IO devices cannot be addressed.
● Incorrect or no configuration
as an I-device:
The LED flashes until at least one controller has correctly established com‐
munication with this I‑Device.
Possible causes:
● Incorrect IP address
● Incorrect configuration / parameterization
● IO controller not connected / switched off, although an Ethernet
connection has been established.
● IN Shared I‑Device operation: all configures IO controllers are not
connected/switched off, but the Ethernet connection is up (link
established to the neighboring device)
● Incorrect or missing device name.
● The response monitoring interval has elapsed
● The CPU is an I‑Device and communication with the higher-level
controller fails

CBE30‑2 power-up stopped,
possible reason: CBE30-2 is plugged into wrong Control Unit.
(CBE30-2 is only supported by SIMOTION D4x5-2 DP/PN, not by SIMO‐
