Failure Alarm Instructions: FAL(006) and FALS(007)
The FAL(006) and FALS(007) instructions generate user-defined errors.
FAL(006) generates a non-fatal error that allows program execution to con-
tinue and FALS(007) generates a fatal error that stops program execution.
When the user-defined error conditions (i.e., the execution conditions for
FAL(006) or FAL(007)) are met, the instruction will be executed and the follow-
ing processing will be performed.

1.
The FAL Error Flag (A402.15) or FALS Error Flag (A401.06) is turned ON.
2.
The corresponding error code is written to A400.
3.
The error code and time of occurrence are stored in the Error Log.
4.
The error indicator on the front of the CPU Unit will flash or light.
5.
If FAL(006) has been executed, the CPU Unit will continue operating.
If FALS(007) has been executed, the CPU Unit will stop operating. (Pro-
gram execution will stop.)
