Simulating System Errors
FAL(006) and FALS(007) can be used to intentionally create fatal and non-
fatal system errors. This can be used in system debugging to test display
messages on Programmable Terminals (PTs) or other operator interfaces.
Use the following procedure.
1,2,3...
1.
Set the FAL or FALS number to use for simulation in A529. A529 is used
when simulating errors for both FAL(006) and FALS(007).
2.
Set the FAL or FALS number to use for simulation as the first operand of
FAL(006) or FALS(007).
3.
Set the error code and error to be simulated as the second operand (two
words) of FAL(006) or FALS(007). Indicate a nonfatal error for FAL(006)
and a fatal error for FALS(007).
To simulate more than one system error, use more than one FAL(006) or
FALS(007) instruction with the same value in A529 and different values for the
second operand.
Name
Address
Operation
Error Code
A400
When an error occurs, the error code is stored in
A400.
FAL Error Flag
A402.15
Turns ON when FAL(006) is executed.
FALS Error Flag
A401.06
Turns ON when FALS(007) is executed.
Executed FAL Num-
ber Flags
A360 to
A391
The corresponding flag turns ON when an
FAL(006) error occurs.
Error Log Area
A100 to
A199
The Error Log Area contains information on the
most recent 20 errors.
Error Log Pointer
A300
When an error occurs, the Error Log Pointer is
incremented by 1 to indicate where the next error
record will be recorded as an offset from the
beginning of the Error Log Area (A100).
Error Log Pointer
Reset Bit
A500.14
Turn this bit ON to reset the Error Log Pointer
(A300) to 00.
FPD Teaching Bit
A598.00
Turn this bit ON when you want the monitoring
time to be set automatically when FPD(269) is
executed.
