Program error
The following errors occur after program execution has been started. PC opera-
tion and program execution will stop and all outputs from the PC will be turned
OFF when any of the following errors occur.
None of the CPU indicators will be lit for the power interruption error, and only the
POWER indicator will be lit for the Expansion Rack power interruption error. The
POWER and WDT indicators will be lit for the CPU error. For all other fatal oper-
ating errors, the POWER and ERROR indicators will be lit. The RUN output will
be OFF.
Probable Cause
A power interruption
longer than the
momentary power
interruption time has
occurred.
A power interruption to an
Expansion Rack has
occurred.
Watchdog timer has
exceeded maximum
setting.
An error has occurred
during check of the PC,
Memory Card or EM Unit
memory, or program
transfer could not be
completed at start-up.
Error has occurred in the
bus line between the
CPU and I/O Units.
The same number has
been allocated to more
than one Expansion
Rack, more than one
CPU Bus Unit, or one I/O
word has been allocated
to more than one I/O Unit.
Watchdog timer error has
occurred during data
transfer between the CPU
and CPU Bus Unit.
Maximum number of I/O
points or I/O Units has
been exceeded in the I/O
Table.
designations registered in
I/O table do no agree with
input/output words
required by Units actually
mounted.
END(001) is not written
anywhere in program or
the program exceeds
memory capacity.
Flag(s) Error code
(A400)
None None Check power supply voltage and
power lines. Try to power-up again.
None None Turn on the power supply to the
Expansion CPU and Expansion I/O
Racks.
None 80FF Turn the power OFF and restart.
A40115 80F1 Check Memory Card and EM Unit
to make sure they are mounted and
backed up properly. Perform a
Program Check Operation to locate
cause of error. If error not
correctable, try inputting program
again.
A40114 80C0 to 80C7 Check cable connections between
or 80CE or the I/O Units and Racks. Verify that
1
80CF terminators are connected, and
then clear the error. A404 contains
the errant rack/slot number.
A40113 80E9 After checking the rack numbers,
unit numbers, or word allocation,
turn the relevant power supply ON,
OFF, and ON again, and then clear
the error. A409 contains the
duplicate rack number, and A410
contains the duplicate unit number.
A40112 8100 to 8115 Check cable connections between
(indicate the CPU and CPU Bus Units, and
Units 0 to 15) then clear the error.
A405 contains the errant unit
number.
A40111 80E1 Check the number of points with I/O
Table Read. If necessary, reduce
number of Units in the system to
keep within maximum number of
I/O points and register the I/O table
again.
A40110 80E0 Check the I/O table with I/O Table
Verification operation and check all
Units to see that they are in correct
configuration. When the system has
been confirmed, register the I/O
table again.
A40109 80F0 Correct the program and then clear
the error.
