Memory error
MEMORY ERR
F1
Memory Unit is
incorrectly mounted or
missing, a Checksum
error has occurred, or
there is an incorrect
instruction.
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.
No END(01) instruction
NO END INST
F0
END(01) is not written

I/O bus error
I/O BUS ERR
Rack no.
*
C0 to C2
Error has occurred in
the bus line between the
CPU and I/O Units.
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.
Too many Units
I/O UNIT OVER
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.
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.
Input-output I/O table error
I/O SET ERROR
E0
Input and output word
designations registered
in I/O table do no agree
with input/output words
required by Units
actually mounted.
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.
FALS error

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.
