Fanuc CNC

This alarm indicates an abnormal voltage condition detected on the common line for digital outputs A0 through A7. This typically signifies an issue with the power supply providing voltage to this group of outputs, or a fault within the connected wiring or load. When active (bit E0 is '1'), the CNC will either issue a status alarm (for I/O Link i) or set a specific bit in the DI area (for I/O Link) to indicate the abnormal state.

This alarm indicates an abnormal voltage condition detected on the common line for digital outputs B0 through B7.
