Information on the non-fatal error can be obtained from the Error Tab Page of
the CX-Programmer’s PLC Error Window. Take corrective actions after check-
ing error details using the display messages and the Auxiliary Area Error
Flags and error information.
• Errors are listed in the following table in order, with the most serious ones

Probable cause
Possible remedy
The executed FAL number 001 to 511 will
be stored in A360 to A391. The number 4
will be added to the front of 101 to 2FF
(which correspond to executed FAL num-
bers 001 to 511) and the result will be
stored in A400 as error code 4101 to
42FF.
Check the conditions for executing FAL
instructions and remove any causes of
the user-defined error.
