Error information
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.
