Additional Information
With a CPU Unit with unit version 1.04 or later that operates as the originator device, a Tag
Data Link Connection Timeout error will occur if a connection is not established with the target
device within one minute after the tag data links are started.
Even after this error occurs, reconnection processing is continued periodically until automatic
recovery is performed.
If the application environment allows you to ignore this error, such as when a target device is
started later than the originator device, you can change the event level to the observation level.
Starting and Stopping Tag Data Links for the Entire Network
You can start and stop tag data links for the entire network from the user program or from the Network
Configurator.
Precautions for Correct Use
Use the same method (i.e., either the user program or the Network Configurator) to both start
and stop tag data links.
For example, if you use the
_EIP_TDLinkStopCmd (Tag Data Link Communications Stop
Switch) system-defined variable stop tag data links, you cannot start them from the Network
Configurator.

Using Commands in the User Program
You can start and stop tag data links on a device basis by changing the values of the following sys-
tem-defined variables from FALSE to TRUE in the user program. (Refer to
Section 3 System-de-
fined Variables Related to the Built-in EtherNet/IP Port on page 3-1.)
• NX701 CPU Unit and NX102 CPU Unit
You can individually start and stop tag data links for each built-in EtherNet/IP port.
• Tag data links start/stop operation switch for built-in EtherNet/IP port 1
_EIP1_TDLinkStartCmd (CIP Communications1 Tag Data Link Communications Start Switch)
_EIP1_TDLinkStopCmd (CIP Communications1 Tag Data Link Communications Stop Switch)
• Tag data links start/stop operation switch for built-in EtherNet/IP port 2
_EIP2_TDLinkStartCmd (CIP Communications2 Tag Data Link Communications Start Switch)
