Error Cause
CPU Unit A parity error
memory error occurred during
an operation
such as reading
the routing
tables.
A memory error
has occurred for
the tag data-
base in the CPU
Unit (CJ2H/
CJ2M CPU Unit
only).
CPU Unit A timeout
event servic- occurred during
ing timeout an operation
such as reading
the routing
tables to the
CPU Unit.
Routing table There is a logic
error error in the rout-
ing table set-
tings.
I/O refresh The EM Area
error bank in which
the device
parameters
were set was
converted to file
memory while
the tag data link
was operating.
Unit operation (Flag Error
status) log
(hex)
Records the error in 0012
the error log. If the
routing tables were
being read, the rout-
ing tables are treated
as missing.
• If a symbol (tag 0017
name) is specified in
the tag data link or
Unit Status Area,
refreshing the user-
specified status area
is stopped and tag
data links will oper-
ate as follows:
• Tag data link com-
munications will be
stopped for origina-
tor connections.
• Communications will
continue for target
connection. If PLC
status is included in
the communications
data, the target node
PLC error flag for
the relevant target
node will be turned
ON.
Note Recovery is
possible from
this error. If
recovery is
achieved, the
tag data links
will be
restarted to
return to nor-
mal status.
Operation stops. 0011
The Unit continues 021A
operating without the
routing tables.
Tag data is not 0347
refreshed if it is
assigned to a non-
existent area.
Note:
Recovery is possible
for this error.
Section 14-2
Countermeasure
Register the rout-
ing tables in the
CPU Unit again
and restart the
CPU Unit.
Replace the CPU
Unit if the error
recurs.
Download the tag
data to the CPU
Unit again.
Replace the CPU
Unit if the error
recurs.
Replace the Ether-
Net/IP Unit or (for a
built-in EtherNet/IP
port) the CPU Unit.
if the error recurs
when the Unit is
restarted.
Create the routing
tables again.
Stop using the EM
Area bank (in
which the device
parameters were
set) as file mem-
ory, or correct the
device parameters.
