Clearing Non-fatal Errors without a Programming Device
 Clearing User-defined Non-fatal Errors
When FAL(006) is executed with N set to 0, non-fatal errors can be cleared. The value of S will
determine the processing, as shown in the following table.
S
&1 to &511 (0001 to 01FF hex)
FFFF hex
0200 to FFFE hex or word specification
 Clearing Non-fatal System Errors
There are two ways to clear non-fatal system errors generated with FAL(006).
• Turn the PLC OFF and then ON again.
• When keeping the PLC ON, the system error must be cleared as if the specified error had actually
occurred.
CS/CJ/NSJ Series Instructions Reference Manual (W474)
Label
ER • ON if N is not within the specified range of 0 to 511 decimal.
• ON if a non-fatal system error is being generated, but the specified error code or error details code is
incorrect.
• OFF in all other cases.
Address
A402.15 ON when an error is generated with FAL(006).
A360.01 to When an error is generated with FAL(006), the corresponding flag will be turned ON. Flags A360.01 to
A391.15 A391.15 correspond to FAL numbers1 to 511 decimal.
Address
A529 A dummy FAL/FALS number is used when a system error is generated with FAL(006). Set the same
dummy FAL/FALS number in this word (0001 to 01FF hex, 1 to 511 decimal).
Address
A100 to A199 The Error Log Area contains the error codes and time/date of occurrence for the most recent 20 errors,
including errors generated by FAL(006).
A400 When an error occurs its error code is stored in A400. The error codes for FAL numbers 0001 to 01FF
are 4101 to 42FF, respectively.
If two or more errors occur simultaneously, the error code of the most serious error will be stored in
A400.
The FAL error of the specified number will be cleared.
All non-fatal errors (including system errors) will be cleared.
The most serious non-fatal error (even if it is a non-fatal system error) that has occurred. When more
than one FAL error has occurred, the FAL error with the smallest FAL number will be cleared.
