Troubleshooting
Section 11-2
Errors Created with FALS Instructions
■
Reference Information
11-2-4 CPU Errors
■
CPU Unit Indicators
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.
CPU Errors
■
Reference 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.
Probable cause
Possible remedy
FALS instruction executed (FALS number 001)
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.
Error flag
