The following table shows how to specify error codes and error details in S
and S+1.
Clearing FALS(007) Fatal System Errors
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.
