3 Assigning Device Variables for CJ-series Units
3-12
CJ-series EtherNet/IP Units Operation Manual for NJ-series CPU Unit (W495)
The status of the tag data links and Ethernet is given in the following variables.
Communications Status 1 (EtherNet/IP Unit to CPU Unit) (
*_CommSta1
)
The status of the tag data links is given in the following variable.
Communications Status Information
Device variable name for CJ-
series Unit
Data
type
R/W
Meaning
Description
*_CommSta1
WORD
R
Communications Sta-
tus 1
Bit 00: Verification Error
Bit 02: Tag Data Link Error
Bit 04: Invalid Communications Parameter
Bit 05: Tag Refresh Error
Bit 06: Tag Database Error
Bit 14: All Tag Data Link Communications Status
Bit 15: Tag Data Link Communications Status
*_TDLOpnErr
BOOL
R
Verification Error
TRUE:
The information registered for a target node
in the tag data link parameters is different
from the actual node information.
Main causes:
•
The specified target does not exist.
•
The variable name does not match.
•
The connection size is different.
•
Connection resources are insufficient.
FALSE: A verification error has not occurred. This
variable also changed to FALSE when a ver-
ification error is cleared.
*_TDLErr
BOOL
R
Tag Data Link Error
TRUE:
There were one or more errors in a connec-
tion as an originator. This status does not
indicate the following errors.
•
Errors in connections as a target
•
Connection timeout due to a Link OFF
Error with the Ethernet switch
FALSE: An error has not occurred in any connection
as an originator.
*_CommParamErr
BOOL
R
Invalid Communica-
tions Parameter
TRUE:
Changes to TRUE when there was an error
in the validation check of tag data link
parameters stored in the Unit's non-volatile
memory, and a checksum error occurred.
(Includes parameters related to basic Ether-
net settings.) The tag data links will stop.
FALSE: The validation check of parameters in non-
volatile memory was normal.
*_TagRefreshErr
BOOL
R
Tag Refresh Error
TRUE:
Changes to TRUE when a specified data
area or address range is not supported in
tag data links.
FALSE: The specified data areas and addresses are
supported in tag data links.
*_TagDbErr
BOOL
R
Tag Database Error
TRUE:
A tag database error occurred in the CPU
Unit when a variable name is used incor-
rectly in a setting for the EtherNet/IP Unit
(tag data link, status area allocations set-
ting, etc.). (CJ2H-CPU6
@
-EIP or CJ2M-
CPU3
@
only)
FALSE: Change to FALSE when a variable name is
not used in a setting for the EtherNet/IP
Unit, when a tag database error has not
occurred, or when a previous error has been
cleared.
