
Tag Data Link Stop Bit ( *_TDLStopCmd )
Stop the tag data links by changing this variable to TRUE. After the tag data links stop, they will
remain stopped until the Unit is restarted or the Tag Data Link Start Bit is changed to TRUE. (The
tag data links will also start automatically when the tag data link parameter settings are downloaded
from the Network Configurator.)
If the tag data links are already stopped, the signal will be ignored.
Message communications can be performed while the tag data links are stopped.
After the tag data links stop, the EtherNet/IP Unit automatically changes the Tag Data Link Stop Bit
to FALSE. Do not force this variable to FALSE. It is automatically changed to FALSE by the Unit.

Adjust Clock Bit ( *_AdjTmCmd )
Automatically adjust the time on the clock by changing this variable to TRUE. The SNTP server used
to adjust the time is set in the Unit Setup.
After the clock time is adjusted, the EtherNet/IP Unit automatically changes the Adjust Clock Bit to
FALSE. Do not force this variable to FALSE. It is automatically changed to FALSE by the Unit.
