Spindle DBB30 function not possible

What does 22295 mean?

The function requested by the PLC via the DBB30 interface could not be executed due to a specific underlying error. This fault disables NC Start in the affected channel and sets interface signals. The exact cause is specified by the error code parameter (%3).

• PLC program logic error attempting to call a DBB30 function with incorrect arguments (e.g., invalid function ID or data block structure).
• Time-out of DBB30 communication between PLC and NC due to excessive network traffic or incorrect communication parameters (e.g., Profinet cycle time mismatch).
• Internal NC processing error during execution of the requested DBB30 function (e.g., insufficient memory, corrupted internal state).
• DBB30 interface configuration error in NC, preventing proper interpretation of PLC requests (e.g., incorrect data block address mapping).

Click steps to track your progress.

1. 1

   1. Verify the PLC program logic, specifically the DBB30 function call block, ensuring correct function identifiers and data structures are being sent.

2. 2

   2. Monitor the communication status between the PLC and NC via the DBB30 interface using diagnostic tools (e.g., TIA Portal online diagnostics, NC trace).

3. 3

   3. Check NC machine data related to DBB30 interface configuration for correct mapping of data blocks (e.g., MD13000 to MD13009 for DBB30 parameters).

4. 4

   4. Restart the NC system (Power OFF/ON) to clear any transient internal NC processing errors.

5. 5

   5. Execute the DBB30 function call using a simplified test program from the PLC to isolate the issue to specific parameters or complex logic.
