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 checking error details using the display messages and the Auxiliary
Area Error Flags and error information.
• Errors are listed in order with the most serious errors first.
• If two or more errors occur at the same time, the most serious error code will be stored in A400.
Errors Created with FAL Instructions
A FAL instruction was executed in the program to
create a non-fatal error.
(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 numbers 001 to 511) and the result will be
stored in A400 as error code 4101 to 42FF. )
