Status
Off The electronics power supply is missing or outside the permissible
tolerance range.
Steady light A different device is connected to port x and a physical connection exists.
Off The electronics power supply is missing or outside the permissible
tolerance range.
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.
The response monitoring interval has elapsed.
Flashing •
• Communication is interrupted.
The IP address is incorrect.
•
Incorrect or no configuration
•
Incorrect parameter settings
•
Incorrect or missing device name
•
IO Controller not connected/switched off, although an Ethernet
•
connection has been established.
Other CBE20 errors
•
Steady light CBE20 bus error
No physical connection to a subnet/switch.
•
Incorrect transmission rate
•
Full duplex transmission is 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 light The Control Unit task system has synchronized with the IRT clock cycle
and data is being exchanged.
Steady light Task system and MC-PLL synchronized with the IRT clock.
Off The electronics power supply is missing or outside the permissible
tolerance range.
Communication Board either defective or not inserted.
Steady light Communication Board is ready and cyclic communication is taking place.
Flashing light The Communication Board is ready, but cyclic communication is not yet
0.5 Hz taking place.
Possible causes:
At least one fault is present.
•
Communication is being established.
•
Steady light Cyclic communication via PROFINET has not yet been established.
However, acyclic communication is possible. SINAMICS waits for a
parameterizing/configuration telegram
