Starting and Stopping Data Links
Section 5-3
5-3-1
Using a Programming Device or a Ladder Program
Set the software switches (AR or DM Start Bit) in the PC to ON using a Pro-
gramming Device or from the ladder-diagram program.
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 or W370) for
details on starting and stopping data links using a Programming Device or
ladder program.
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.
