The data links will start when the Start Bit changes from OFF to ON or is already
ON when power is turned ON. The data links will stop when the Start Bit changes
from ON to OFF.
Note
1. Refer to the Controller Link Units Operation Manual (W309) for details on
starting and stopping data links using a Programming Device or ladder pro-
gram.
2. The data in the AR and DM Areas is retained when power is turned off.
Therefore, by setting in the AR and DM Areas can be made in advance to
start data links as soon as power is turned on. It is recommended to set the
Start Bit to ON in multiple nodes that are participating in the data link so that
the data links will start even if the startup node is down. The same data link
settings must be set in these nodes for automatically set data links.
