3 Assigning Device Variables for CJ-series Units
3-10
CJ-series EtherNet/IP Units Operation Manual for NJ-series CPU Unit (W495)
Unit Status 2 (EtherNet/IP Unit to CPU Unit) (
*_UnitSta2
)
*_IPAdrDupErr
BOOL
R
IP Address Duplica-
tion Error
TRUE:
An ARP was sent with the specified IP
address, indicating that an IP address dupli-
cation was detected. An address duplication
is detected if there is an ARP response. If
there is an ARP response, it is assumed that
there is an address duplication. This vari-
able changes to FALSE if the power is
cycled, the Controller is reset, or the Ether-
Net/IP Unit is restarted. (The Ethernet inter-
face stops.)
FALSE: Other than the above.
Default: FALSE
*_LkOffErr
BOOL
R
Link OFF Error
TRUE:
An error occurred in establishing a link with
the Ethernet switch.
FALSE: A link was normally established with the
Ethernet switch.
Default: FALSE
*_UserStaAreaCfgErr
BOOL
R
Status Area Layout
Setting Error
TRUE:
There is an error in the layout settings for
the allocated words in the CIO Area. In this
case, operation uses the default layout of
the allocated words in the CIO Area. How-
ever, if a word that does not exist is speci-
fied, the user-set pattern of the layout of the
allocated words in the CIO Area is used for
operation and the user settings area is not
refreshed.
FALSE: There are no problems in the layout settings
for the allocated words in the CIO Area.
Default: FALSE

*_UnitSta2
WORD
R
Unit Status 2
Bit 00: Online
Bit 01: Tag Data Link in Operation
Bit 02: Operating IP Address Change
Bit 11: User Settings Area Enabled

*_ETNOnlineSta
BOOL
R
Online
TRUE:
The Unit is online. (The EtherNet/IP Unit can
perform communications processing.)
FALSE: The Unit is not online. The EtherNet/IP Unit
goes offline in the following cases:
•
IP Address Duplication Error
•
Ethernet Communications Controller Error
(hardware error)
•
BOOTP Server Error
