Error and message
Power interruption
No message.
CPU error
No message, or the message displayed
before the error.
Memory error
No END(01) instruction
I/O bus error
Too many Units
Input-output I/O table error
FALS error
other fatal operating errors, the POWER and ALARM/ERROR indicators will
be lit. The RUN output will be OFF.
FAL no.
None Power has been
interrupted for at least
10 ms.
None Watchdog timer has
exceeded maximum
setting (default setting:
130 ms).
F1 Memory Unit is
incorrectly mounted or
missing, a Checksum
error has occurred, or
there is an incorrect
instruction.
F0 END(01) is not written
anywhere in program.
C0 to C2 Error has occurred in
the bus line between the
*
CPU and I/O Units.
Rack no.
E1 Two or more Special I/O
Units are set to the
same unit number.
CPU01-E, 02: A unit is
installed in an unusable
slot.
CPU11-E: Two
SYSMAC NET Link or
SYSMAC LINK Units
share the same
operating level.
E0 Input and output word
designations registered
in I/O table do no agree
with input/output words
required by Units
actually mounted.
01 to 99 FALS has been
or 9F executed by the
program. Check the FAL
number to determine
conditions that would
cause execution (Set by
user or by system).
Probable cause
Check power supply voltage
and power lines. Try to
power-up again.
Restart system in PROGRAM
mode and check program.
Reduce cycle time or reset
watchdog timer if longer time
required. (Consider effects of
longer cycle time before
resetting.)
Check Memory Unit to make
sure it is mounted and backed
up properly. Perform a Program
Check Operation to locate
cause of error. If error not
correctable, try inputting
program again.
Write END(01) at the final
address of the program.
The rightmost digit of the FAL
number will indicate the number
of the Rack where the error was
detected. Check cable
connections between the I/O
Units and Racks.
Perform the I/O Table Read
operation to check unit
numbers, and eliminate
duplications.
CPU01-E: Use slots 1 to 5 only.
Do not install Expansion I/O
Racks.
CPU02: Use slots 1 to 5 only.
Do not install Remote I/O
Master Units.
CPU11-E: Check the SYSMAC
NET Link and SYSMAC LINK
Unit operating levels and
eliminate duplications.
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.
Correct according to cause
indicated by FAL number. If FAL
number is 9F, check watchdog
timer and cycle time, which may
be to long. 9F will be output
when FALS(07) is executed and
the cycle time is between 120
and 130 ms.
