Status Flags Related to Tag Data Links

The status of the tag data links is reflected in the following device variables for the CJ-series Unit.
*_TargetPLCMdSta [0] to [63] (Target Node PLC
Operating Flags)
* Corresponds to the operating information in the
Controller status.
*_TargetPLCErrSta [0] to [63] (Target Node PLC
Error Flags)
* Corresponds to the Controller Error Information
in the Controller status.
*_EstbTargetSta [0] to [63] (Normal Target Node
Table)
* This status is not included in the Controller sta-
tus.

Description
This variable shows the operating status of the target PLCs
that are connected with the EtherNet/IP Unit as the origina-
tor. The information in this area is valid only when the corre-
sponding Normal Target Node Table is TRUE. If the
corresponding Normal Target Node Table is FALSE, the Tar-
get Node PLC Operating Flags indicates the previous oper-
ating status.
Array[x] is TRUE: The target PLC with a node address of x is
in operating status.
Array[x] is FALSE: Other than the above.
This variable indicates that the connection for the Registered
Target Node Table was not established or that an error
occurred in the target PLC. The information in this area is
valid only when the corresponding element in the Registered
Target Node Table is TRUE.
Array[x] is TRUE: The Registered Target Node Table for a
node address of x is TRUE, and the Normal Target Node
Table is FALSE or the Target Node PLC Error Flags is TRUE.
Array[x] is FALSE: When the Registered Target Node Table
for a node address of x is FALSE, or when the Registered
Target Node Table is TRUE and the Normal Target Node
Error Information is TRUE.
This is when the Controller Error Information is FALSE.
This variable gives a list of nodes that have normally estab-
lished EtherNet/IP connections.
Array[x] is TRUE: The connection to the node with a node
address of x is established normally.
Array[x] is FALSE: A connection is not established or an
error has occurred.
