Probable Cause
The cycle time has
exceeded the maximum
cycle time set in the PC
Setup.
The program contains an
error in SFC syntax or an
END(01) instruction is
missing.
FALS has been executed
by the program. Check
the FAL number to
determine conditions that
would cause execution.
Note 1. Error codes 80C0 to 80C7 indicate Rack numbers 0 to 7, respectively. Error
codes 80CE and 80CF indicate that the terminator is missing in operating
system 0 and 1, respectively.
2. The total number of I/O words allocated to the CPU, CPU Expansion, and
Expansion I/O Racks is contained in A407. A408 contains the total number
of I/O words allocated to the SYSMAC BUS/2 System, and A478 contains
the total number of I/O words allocated to the SYSMAC BUS System.
3. The maximum cycle time since start-up is contained in A462 and 463, and
the present cycle time is contained in A464 and 465.
The following table describes SFC fatal errors. When an SFC fatal error occurs,
the SFC Fatal Error Flag (A40107) is turned ON, and the error code is output to
A414.
Error code
(A418)
There is not even one active step.
There is no subchart entry step for the subchart
dummy step, or the subchart number is
incorrect.
There is not even one initial step in the

There is no action program set, or the bit
address for the action is incorrect.
There is no transition program set, or the bit
address for the transition is incorrect.

Flag(s) Error code
(A400)
A40108 809F
A40107 80F3
A40106 C101 to C2FF
correspond to
FAL numbers
001 to 511.
Probable cause
Section 8-4
Possible remedy
Change the program or the
3
maximum cycle time.
Correct the program and then clear
the error. (Refer to the next table for
information on SFC fatal errors.)
Check to be sure that all programs
end in END(01).
Correct according to cause
indicated by FAL number.
Possible remedy
Check the program.
Check and then re-transfer
the program.
Create an initial step and
then re-transfer the program.
Check and then re-transfer
the program.
Check the program.
Re-transfer the program.
