CBE20 – Communication Board Ethernet (option G33)
Table 10- 9 Description of the LEDs on the CBE20
LED Color State Description
--- OFF The electronics power supply is missing or lies outside the permissible
tolerance range.
Link port
Green Steady light A different device is connected to port x and a physical connection exists.
--- OFF The electronics power supply is missing or lies outside the permissible
tolerance range.
Activity
port
Yellow Steady light Data is being received or sent at port x.
--- OFF If the link port LED is green:
The CBE20 is operating normally, data is being exchanged with the
configured IO Controller.
Flashing - The response monitoring time has elapsed.
- Communication has been interrupted.
- The IP address is incorrect.
- Incorrect or missing configuration.
- Incorrect parameterization.
- Incorrect or missing device name.
- IO Controller not present/switched off but Ethernet connection present.
- Other CBE20 errors
Fault
Red
Steady 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
internal substitute clock is generated.
Flashing Control Unit task system has synchronized with the IRT clock and data is
being exchanged.
Sync
Green
Steady light Task system and MC-PLL have synchronized with the IRT clock.
--- OFF The electronics power supply is missing or lies outside the permissible
tolerance range.
Communication Board either defective or not inserted.
Steady light Communication Board is ready and cyclic communication is taking place. Green
Flashing, 0.5 Hz The Communication Board is ready, but cyclic communication is not yet
taking place.
Possible causes:
- At least one fault is pending.
- Communication is being established.
Steady light Cyclic communication via PROFINET has not yet been established.
However, acyclic communication is possible. SINAMICS is waiting for a
parameterization/configuration telegram.
OPT on
the Control
Unit
Red
Flashing, 0.5 Hz The firmware download to the CBE20 has failed.
Possible causes:
- The CBE20 is defective.
- The memory card for the Control Unit is defective.
In this state, the CBE20 cannot be used.
