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. A CPU error may have occurred if nothing is shown
on the 7-segment display or the same message remains on the display.
Probable cause
A WDT (watchdog) error occurred in the
CPU Unit. (This does not occur in normal
use.)
■ Reference Information
Error flag
Error code (A400)
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.
Possible remedy
C100 hex will be added to the FALS number (001 to 1FF hex)
and the result will be stored in A400 as the error code (C100 to
C2FF hex).
Check the conditions for executing FALS instructions and
remove any causes for the user-defined error.
