Starting and Stopping Data Links
Section 5-3
5-3-1
Using a Programming Device or the User Program
Set the software switch (AR or DM Start Bit) in the PLC to ON using a Pro-
gramming Device or from the user 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
The data in the AR and DM Areas is retained when power is turned off. There-
fore, 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 partici-
pating 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 automati-
cally set data links.
