6-1-9 CPU Errors
z CPU Unit Indicators
: Not lit : Flashing : Lit
A CPU error or fatal error may have occurred if the ERR/ALM indicator lights during operation (RUN
mode or MONITOR mode), the RUN indicator turns OFF, and operation stops.
z Reference
Note Just as when a CPU error occurs, the RUN indicator will turn OFF and the ERR/ALM indicator will
light when a fatal error occurs. Connecting the CX-Programmer, however, is possible for fatal
errors but not for CPU errors.
If the CX-Programmer cannot be connected (online), a CPU error has probably occurred.
