Clearing FALS(007) Fatal System Errors (CS1-H, CJ1-H, CJ1M, and CS1D
CPU Units Only)
There are two ways to clear fatal system errors generated with FALS(007).
1. Turn the PLC OFF and then ON again.
2. When keeping the PLC ON, the system error must be cleared as if the
specified error had actually occurred.
Clearing FALS(007) User-defined Fatal Errors
To clear errors generated by FALS(007), first eliminate the cause of the error
and then either clear the error from a Programming Device or turn the PLC
OFF and then ON again.
