Failure Alarm Instructions: FAL(006) and FALS(007)

• The following instructions will create a fatal error to prevent the program

from being executed when the lot number does not end in 05.

First Cycle Flag

• The following instructions will create a fatal error to prevent the program

from being executed when the lot number does not begin with 23Y.

First Cycle Flag

This section introduces the following functions.

• Failure Alarm Instructions: FAL(006) and FALS(007)

• Failure Point Detection: FPD(269)

• Output OFF Bit

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.)
