State
OFF If the link port LED is green:
The CBE20 is operating normally, data is being exchanged with the con-
figured IO Controller.
Flashing light - The response monitoring time has elapsed.
- Communication has been interrupted.
- The IP address is incorrect.
- Incorrect or missing configuration.
- Incorrect parameter assignment.
- Incorrect or missing device name.
- IO controller not present/switched off but Ethernet connection present.
- Other CBE20 errors.
Continuous light CBE20 bus fault
- No physical connection to a subnet/switch.
- Incorrect transmission rate.
- Full-duplex transmission not activated.
OFF If the link port LED is green:
Control Unit task system is not synchronized with the IRT clock. An inter-
nal substitute clock is generated.
Flashing light Control Unit task system has synchronized with the IRT clock and data is
being exchanged.
Continuous light Task system and MC-PLL have synchronized with the IRT clock.
State
OFF Electronics power supply is missing or outside permissible tolerance
range.
The CBE20 is defective or not inserted.
Continuous light CBE20 is ready and cyclic communication is taking place.
0.5 Hz flashing CBE20 is ready but cyclic communication is not running.
light Possible causes:
- Communication is being established.
-At least one fault is present.
Continuous light Cyclic communication via PROFINET has not yet been established.
However, acyclic communication is possible. SINAMICS is waiting for a
parameterization/configuration telegram.
0.5 Hz flashing The firmware download to the CBE20 has failed.
light Possible causes:
- The memory card of the Control Unit is faulty.
- The CBE20 is out of order.
The CBE20 cannot be used in this state.
2 Hz flashing Communication between the Control Unit and the CBE20 is faulty.
light Possible causes:
- The CBE20 was removed following power-up.
- The CBE20 is defective.
