Even if PLC Setup word 129 bit 15 is set to 1 (Do not record FAL Errors in
Error Log.), the following errors will be recorded:
• Fatal errors generated by FALS(007)
• Non-fatal errors from the system
• Fatal errors from the system
• Non-fatal errors from the system generated intentionally with FAL(006) or
FPD(269)
• Fatal errors from the system generated intentionally with FALS(007)
Clearing Non-fatal Errors without a Programming Device
1. 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 ta-
ble.
S
&1 to &511 (0001 to 01FF hex) The FAL error of the specified number will be
FFFF hex
0200 to FFFE hex or word
specification
2. Clearing Non-fatal System Errors (CS1-H, CJ1-H, CJ1M, and CS1D CPU
Units Only)
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.

When more than one FAL error has occurred,
the FAL error with the smallest FAL number will
be cleared.
Operation
ON if N isn't within the specified range of 0 to 511 deci-

ON if a non-fatal system error is being generated (CS1-H/
CJ1-H/CJ1M/CS1D Only), but the specified error code or
error details code is incorrect.
OFF in all other cases.
