9 Tag Data Link Functions
(They are automatically started after the CPU Unit's power is turned ON or the Unit is restarted.)
Additional Information
With a CPU Unit 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 by instructions from the user program or
operations 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 execute an instruction to stop tag data links, you cannot restart them from
the Network Configurator.
l Executing Instructions in the User Program
You can start tag data links for the entire network by executing the TDLinkStartConnection (Start
Tag Data Link Target Connection) instruction from the user program. You can stop tag data links for
the entire network by executing the TDLinkStopConnection (Stop Tag Data Link Target Connection)
instruction.
Refer to Section 13 Instructions Specific to NX-series EtherNet/IP Units on page 13-1 for de-
tailed instruction specifications.
l Using the Network Configurator
You can select I/O Connection - Start or Stop from the Network Menu to start and stop tag data
links for individual devices.
Starting and Stopping Tag Data Links for Individual Devices
l Using the Network Configurator
You can start and stop tag data links on a device basis (at the originator) by selecting Monitor from
the Device Menu and performing the following operation in the Connection Tab Page in the
Monitor Device Dialog Box.
You can start and stop tag data links for each of the EtherNet/IP ports 1 and 2 connected to the
Network Configurator.
