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.
Note The CS1G/H-CPU@@ (-V1) and CJ1@-CPU@@ CPU Units do not support
this function.
1. Set the FAL or FALS number to use for simulation in A529. (A529 is used
when simulating errors for 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 operation (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 as described above.

Note Use the same methods as for actual system errors to clear the simulated sys-
tem errors. Refer to the CS-series Operation Manual or the CJ-series Opera-
tion Manual for details. All system errors simulated with FAL(006) and
FALS(007) can be cleared by cycling the power supply.
Address
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).
A50014 Turn this bit ON to reset the Error Log Pointer
(A300) to 00.
A59800 Turn this bit ON when you want the monitoring
time to be set automatically when FPD(269) is
executed.
Address
A529 Set a dummy FAL/FALS number to use to simu-
late the system error.
0001 to 01FF Hex: FAL/FALS numbers 1 to 511
0000 or 0200 to FFFF Hex: No FAL/FALS number
for system error simulation.
Set FAL number 100 in A529.
