APS: NCB error %d with request of handler structure.

What does 898 mean?

An error occurred (identified by NCB error %d) when the system attempted to request the handler structure necessary for copying the NC bit interface. This is a PLC error, indicating a failure in preparing for interface communication, with no error recovery possible.

• Error requesting handler structure for copying the NC bit interface.

Click steps to track your progress.

1. 1

   Verify the specific NCB error code (the %d value) from the PLC diagnostic buffer or HMI to gather full context of the fault.

2. 2

   Inspect the PLC program and configuration for the NC bit interface, ensuring correct parameters and resource assignments for handler structure requests.

3. 3

   Check the operational status and diagnostic LEDs of any communication modules or interface cards within the PLC rack that facilitate the NC bit interface.

4. 4

   Verify the operational status and readiness of the connected NC (Numerical Control) unit to ensure it can respond to interface requests from the PLC.

5. 5

   Perform a controlled power cycle of the entire Bosch Rexroth Motion Control system to reinitialize all components and observe if the error is cleared.
