Steven LucasAug 18, 2025
If the Siemens Controller CBL detects data communication errors, especially CRC errors during data transmission, check the shield connection of the cable at the housing of the CU and at all CC-Link stations for EMC faults. Also, verify the cable length of the CC-Link bus according to the data transmission rate.

If the Siemens Controller CBL detects no carrier at CC-Link, check the connection to CC-Link. Specifically, inspect the connector and ensure the correct connection of signals DA, DB, DG, and SLD at both the CBL and CC-Link master.

If the Siemens Controller CBL communicates correctly but there is no data transfer with the PLC CPU, verify that the PLC CPU status is set to 'RUN'. If the PLC CPU is in 'STOP' or 'FAULT' mode, it will prevent data transfer.

What to check if Siemens Controller CBL detects carrier at CC-Link but doesn’t answer?

Morgan JonesAug 26, 2025
If the Siemens Controller CBL detects a carrier at CC-Link but doesn’t answer, check the following:
* Data transmission rate in P711 to ensure it is the same as the CC-Link master.
* CC-Link station number in P918 to ensure it matches the configuration in the PLC programming software.
* Verify that the station address is not already in use.
* Confirm the PLC network configuration: remote device station, occupies 1 station, with station number like P918.

What are the possible causes and solutions if Siemens Controller CBL is defective?
A
April CookAug 28, 2025
If you observe that the Siemens Controller CBL is defective, it could be due to a faulty CU, Tech-board, or the CBL itself. Check the connection between the CBL and other boards. Try restarting the converter with a power-down/up cycle. Also, inspect the earth/protective conductor for EMC faults.

If there's a communication error between the base board and the Siemens Controller CBL, it might be due to a defective CU, Tech board, or the CBL itself. Check the connection between the CBL and other boards. Try restarting the converter with a power-down/up cycle. Also, inspect the earth/protective conductor for EMC faults.

What to check if Siemens Controller CBL receives and sends frames?
M
Mr. Christopher RogersSep 4, 2025
If the Siemens Controller CBL is receiving and sending frames, verify the PLC network configuration. Ensure it is set up as a remote device station, occupies 1 station, with a station number like P918.

Why is Siemens Controller CBL waiting for start of parameterization?
L
Lori PhillipsSep 6, 2025
If the Siemens Controller CBL is waiting for the start of parameterization or initialization by the converter or inverter, note that this sequence is automatically initiated by the CU after power-up and re-parameterizing.

What happens when Siemens Controller CBL is waiting for completion of parameterization?
C
Caroline JacobsSep 9, 2025
The Siemens Controller CBL normally handles the completion of parameterization or initialization very quickly, so this LED status is typically not visible.
