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.
