Errors Related to CPU Unit Data Exchange
Flash-
ing red Not lit H1 Duplicate unit
number The same unit num-
ber is set on another
Unit. Operation stops. --- Set the unit numbers
correctly and restart
the EtherNet/IP Unit.
Flash-
ing red Not lit H2 CPU Unit faulty --- Operation stops. --- Replace the CPU
Unit if the error recurs
when the CPU Unit is
restarted.
Lit red Not lit H3 EtherNet/IP Unit
faulty --- Operation stops. --- Replace the Ether-
Net/IP Unit if the error
recurs when the Unit
is restarted.
Flash-
ing red Not lit H4 Node address
setting error The node address set
on the switches is
invalid (00 or FF.) Operation stops. --- Set the node address
correctly and restart
the EtherNet/IP Unit.
Flash-
ing red Not lit H6 CPU Unit faulty --- Records the error in the
error log (time/date all
zeroes).
Operation stops.
000F Replace the CPU
Unit if the error recurs
when the CPU Unit is
restarted.
Flash-
ing red Not lit H7 I/O table not reg-
istered The CPU Unit's I/O
table is not regis-
tered. Operation stops. 0006 Create the I/O table.
Flash-
ing red --- H8 Restoring simple
backup data
failed. Restoring simple
backup data failed for
some reason. All settings for the Ether-
Net/IP Unit or built-in port
will be cleared except for
the following errors: File
missing, memory not
mounted, or inconsistent
models. --- If the problem per-
sists even when you
repeat the simple
backup procedure,
replace the SD Mem-
ory Card, the Ether-
Net/IP Unit, or, if the
problem is with the
built-in port, the CPU
Unit.
Flash-
ing red --- H9 I/O bus error An error occurred
while exchanging
data with the CPU
Unit. • If the Unit is the origina-
tor of the tag data link
connection, it stops
communications.
• Communications will
continue for target con-
nection. If the Unit is
the target of the tag
data link connection
and the Controller sta-
tus is included in the
communications data,
the corresponding ele-
ment in the Target
Node PLC Error Flags
will change to TRUE.
000E Check and correct
the CPU Unit's oper-
ating environment.
