Repair Steps & Checklist
Click steps to track your progress.
- 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
Inspect the PLC program and configuration for the NC bit interface, ensuring correct parameters and resource assignments for handler structure requests.
- 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
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
Perform a controlled power cycle of the entire Bosch Rexroth Motion Control system to reinitialize all components and observe if the error is cleared.
