CNI RT 480 control unit

The CNI RT 480 is an industrial CNC control unit originally used in Biesse woodworking machines and later replaced by the XNC series; it integrates a PLC, motion controller, and user interface on a single board. Common failure points for this model include power‑supply board degradation (brownouts or overvoltage), I/O module corrosion, and firmware corruption due to aging non‑volatile memory. First‑check diagnostics should verify 24 V DC input stability, inspect the main board for burnt components or loose solder joints, and review any stored error codes via the diagnostic port or serial console. If power is stable and no obvious hardware faults are found, a firmware recovery or reflash may be required.[oss-gpt-20b]
