State
OFF Electronics power supply is missing or outside permissible
tolerance range.
Continuous A different device is connected to port x and a physical
connection exists.
OFF Electronics power supply is missing or outside permissible
tolerance range.
Continuous Component active (DC link discharge via braking resistor
in progress).
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 •
Communications 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
•
Continuous 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 The Control Unit task system has synchronized with the
IRT clock cycle and data is being exchanged.
Continuous Task system and MC-PLL have synchronized with the IRT
clock.
OFF Electronics power supply is missing or outside permissible
tolerance range.
Communication Board either defective or not inserted.
Continuous Communication Board is ready and cyclic communication
is taking place.
Flashing The Communication Board is ready, but cyclic
0.5 Hz communication is not yet taking place.
Possible causes:
At least one fault is present.
•
Communication is being established.
