Operand [D2] setting
Specify the area that stores the execution result. One of the following execution codes is stored.
Name
Normal end
In progress
Timeout
Multiple executions
[D]
Communication error
CIP error
EtherNet/IP communication
preparation incomplete
[D2+1] CIP general status
[D2+2] CIP extended status
■
Usage example
Example 1) Acquires the node status of node number 1.
● EtherNet/IP configuration setting
The EtherNet/IP devices that the node status is acquired should be registered in the scan
list.
Node
1
2
There is no problem even if the valid/invalid flag is invalid when acquiring the node status.
Select valid or invalid to determine whether to perform the cyclic communication or not.

Sample program
● The UNITSEL instruction is used to specify the connection number of the built-in ET-LAN in
the CPU unit.
● The acquisition result of the node status is stored in DT100 and the execution result is in
DT2000. When the operation is complete successfully, 0 is stored in DT2000, and the node
status is stored in DT100 and subsequent DTs.

Description
The acquisition of a specified node status is complete.
The acquisition of a specified node is in progress.
Communication timeout (10 seconds)
Multiple execution of the EIPNDST instruction
In the case of communication errors
In the case of a CIP error
When the preparation of EtherNet/IP communication is
incomplete
If the value of [D] is "5", CIP general status and CIP
extended status are stored. If the value of [D] is not "5",
"0" is stored in [D2+1] and [D2+2].
