MODULE
An NMI occurred on the option board.
The option board may be faulty. See Chapter 7.
973 NON MASK INTERRUPT NMI occurred for an unknown reason. Or, a communication error
occurred in the FANUC I/O Link slave function.
974 FBUS ERROR A bus error occurred on the FANUC bus.
The base PC board or option board may be faulty.
975 BUS ERROR A bus error occurred on the motherboard.
The base PC board may be faulty.
976 LBUS ERROR A bus error occurred on the local bus.
The base PC board may be faulty.
977 NMI FROM SLAVE SLC A communication error occurred in the FANUC I/O Link slave function.
See the descriptions of alarms 950 and 973 in Chapter 7.
